I want to point out that, at this point, that I purchased this heater out of my own pocket ... VEVOR approached me afterwards, so I purchased this heater from them based on my own research, and as you guys can see, it has taken all of the abuse I have thrown at it !

Actual description: I think the title says it all. I've got a cat off of a weed trimmer and I'm going to install it in my heater and fire it up ! - Наука та технологія
Kudos to whoever thought of trying a carburetor, that will be another fun one to watch.
Yeah... I freaked out when I was that comment... and felt like an idiot for not coming up with the idea ... I've even talked about people doing carburetor like things... Should be exciting !
I just got done installing a section of catalytic converter from my dodge caravan in the burn chamber of my diesel heater this morning. It definitely feels warmer I don’t have any smoke. I’m gonna measure the temps And take it back out and measure again.
Very cool ! I'd love to know the results ... Thanks for the comment.
Oooh man! That's just awesome! I did not expect it to corrode like that.
Yeah... I didn't think so either... It's a pretty harsh environment apparently.
I find it extraordinary that the folks that manufacture these have dialed it to such an efficient design.
I think this is great considering the changing times. Every home should have an off-grid source of heating. Is this a larger plan? I don't know.
But I can say for sure, these heaters are safe enough, if you could be in a grid-down situation for more than 48 hours, you will be glad to have a sourced of heat.
It is pretty incredible, yes. They did a great job.
For now, I am just trying to do something that keeps me entertained, keeps my brain going and saves me some money, but who knows what it will lead to.
For sure... You wouldn't need much of a battery bank to power one of these heaters and a few solar panels would easily top your batteries back up.
6:00 you got me there haha
If you made a mounting that you can adjust the baffle plate space to burner and then you can adjust the flame better.
Better heat efficiency maybe
Lower exaust temp possible i think if you dial it in correctly it can run super efficient and can be adjusted to different oils maybe
LOL... indeed... who wouldn't want to watch this to see what happens.
I'm thinking of doing this again but with a large cat... The one that I used was off of a weed trimmer and it's probably about 6 times too small.. One for a car is more work, but more sensible.
@@loweredexpectations4927 would love to see a video on that large cat :D
You come up with ideas that I would never have thought of. I love your attempts and look forward to each new episode. Please make sure that your garage doesn't end up on fire in these crazy experiments! Thank you for taking us with you.
Thanks for the comment. This was the idea of a viewer, not my idea, but thanks, haha. I will do my best not to burn anything that I didn't intend to burn...🤟
@@loweredexpectations4927 your welcome 🤗
@@roastntoast7550 🤟
First job for the Ultrasonic Cleaner, the exhaust!
Haha... Yeah. That's a good idea.. I think it will be very satisfying.
If you get an automotive cat and remove the Honey comb you can chip away at it to make it fit the chamber. Won't work but there you go
I'm positive I already responded to this...🤔
Catalyyyyyyyytic 😂 haha great video
I would like to come back to this some day with a larger one.
next try to roll some fiberglass mat and put into the burn chamber :)
Looks over his shoulder..... Are you watching me... How did you know 🤣 1mm thick CSM some 6oz cloth and I even have some carbon fibre....
For a minute there I thought you were Ryan Reynolds trying to sell me one of his brand new cell phones on his new cell system OK let’s get back to the diesel heater!
🤣 HAHA.... Right... I've had the Ryan Reynolds comment a few times and I don't get it... Let's stick to diesel heaters and jetskis !
Get the Cat out of the flame front and place it further down the exhaust stream like a car. Then bonus, extract the extra heat generated by it by having the exhaust ran through a heat exchanger!
I have had this comment a few times, and it means that I didn't do my job in explaining why I did what I did, haha... I kinda did this on purpose (not explaining it well) to try to make it more entertaining and interactive....
The reason for the cat being so close was to try to use some of the heat from it to help the oil burn cleaner. The area where the oil comes in tends to only run about 180C and it should be 250 ish to flash off the oil.
@Lowered Expectations Got it that makes sense, too bad it got burned up...
The burn chamber should be left out when the catalytic converter is putted in. The CAT might have melted due to too much unburned fuel. More air might be needed in the mixture.
Thanks for the comment.
Not 100% sure what you mean, but the burn chamber tube is necessary to guide the hot gasses along the exchanger... without it, the gasses will just exit the exhaust directly below where the fuel comes in and shoot flames out the exhaust.
With the particular controller I was using, the fuel air ratio is not adjustable, unfortunately.
It is normal at startup for a bit of smoke or vapors to escape, as the catalytic converter needs to reach reactive temperatures first.
It shouldn't take long for it to get nice and warm glowing in a light amber color.
It would be really cool to stuff a large one in there and cut the end off of the heat exchanger and observe it.
@@loweredexpectations4927 get a piece broken out of a car cat, chipped away on the sides, until you have a long round piece. Stick it in a borosilicate glass tube, attach to a straight piped exhaust combustion engine anything. Maybe even the exhaust of your heater. I have seen it in school, the teacher had a little jet engine blowing straight into the glass tube filled with a Ford ceramic catalytic converter honeycomb chunk. Don't cut to observe, just drill a hole and put a heat resisting optic into harms way, without changing much on the system.
@@sebastiank1714 That sounds awesome. "heat resisting optic" Sounds expensive, haha.
There's a reason cat converters on cars are 3 times the width of the exhaust pipes connecting them. I think your idea will work but try a cat converter for a Geo Metro 3cyl car. That will give you the larger surface area you need. The corrosion could be the detergent in the oil, bad stuff for burning. The cat doesn't have to be so close to the fire. Look at cars, the cats 1 to 3 feet away from the exhaust manifold.
Right on. Thanks for the info.
The reason for the cat being so close was to try to use some of the heat from it to help the oil burn cleaner. The area where the oil comes in tends to only run about 180C and it should be 250 ish to flash off the oil.
try the burn chamber installed backwards and put the cat in near the end.
as i've se3n in david mcluckys video the flamefront ends at 60-70% of the burn chamber.
the remainings of the cat should survive then.
after all you're possibly better off with a cat from a mower traktor.
regarding the carb idea: if you fuel it with gasoline or methanol in a stoichometric mix it will backfire like nothing good ! might smash the whole burner fan and rip the intake tube in pieces in that process.
so keep the mixture WELL in the lean region.
oil and diesel are wayyy to thick to be vaporized that way so it will only work for a meth or gas addition for cleaner burn.
and: you need to insulate the intake pipe to prevent fuel condensation downstream from the carb. vaporizing cools the mix. pre-heating the tube with existing hot air would help with that... dewpoint and all that crap... you know...
I wrote a super long detailed reply and then hit "cancel" instead of "reply" ... Thanks for your detailed comment. I will take all of this into consideration.
I have fed gasoline and alcohol into the inlet tube and had it run but also had it backfire several times. It appears to have lots of venting space and doesn't explode.
Catalytic converter at the bottom of the machine where the exhaust pipe hooks on
I guess I didn't make it clear in this video, but the idea of running the cat where I did was to try to get the vaporization area to heat up and flash the oil off. I made a few videos about this leading up to this one.
Putting the cat further down stream would work to clean up the smoke, but it would do nothing to heat up the area where the oil comes in.
Should have tested with a clean fuel first to determine effect of cat converter.
Contaminants in used oil might react with the catalyst at high temperatures forming errodable non catalytic compounds.
Thanks for the comment. I suppose a test with diesel would have been a good baseline... and would have told me if it failed due to where it was installed or because of the waste fuel.
I would like to try this with a larger cat at some point in the future.
Nice! Ask Vevor for a controller that will allow you to adjust fan speed and fuel pump rate?
Curious what would’ve happened if the cat had remained in place.
I've already got one... just need time for testing / editing.🤟
I suspect that it would have choked it up, based on tests both before and after this... I suppose I could try it again as I still have it...
Awesome that you got the adjustable controller!
You need to watch david mcluckie he has a heater with a clear burn chamber so you can understand whats going on in there cause your cat needs to go towards the end, not up against your flame area. You really need to be able to control fuel flow and air to get the right afr. That controller sucks. Can you say afterburner controller.
Thanks for the comment. I have watched most of Daves videos, and I have seen a few where he has the end cut off.... Great guy
I have received a new controller, tho it is not a fancy afterburner... I don't have the funds for that yet.

You need to do some exhaust tests to see if the cat is deducing emissions
Yeah... I really wish I had the tools to do that. I don't currently even have a CO meter... Sadly.
👍
🤟
before even watching .... cats are never used on diesel because of the possibility of soot and the low burn temperatures (the cat never gets hot enough to do its cat thing) .. and waste oil never used because even the tiniest amount of lead (from wearing bearings, etc ... leaded fuel is very rare nowadays outside of the airport) will poison it. a carburetor is never used on a diesel engine because of timing issues (fuel has to be delivered AFTER the compressed air heats the hot air) .. in the case of a linear burner, its more like a jet engine .. air in, fuel injected later .. fire. Exhaust hacks... always have the exhaust pipe in a downward slope (or straight down) this keeps any moisture from accumulating. I put fans on the hottest part of the exhaust train to recover a considerable amount of heat. one time I put 'fins' on the part closest to the heater and sucked a HUGE amount of heat out of it. after watching: cats go downstream of the exhaust, but never contact flame or raw unburned fuel (this is one reason cats are NEVER on carb'd gasoline engines)
Thanks for the comment.
I'm not sure if there is any difference in the catalyst, but this cat came off of a two cycle weed trimmer and was used specifically to avoid the mess of oil that normally comes out if the exhaust. The idea here was simply to see if the cat would create a lot of heat.
The motor oil that I am using comes from utility engines that do not have bearings at all (crank' cam, big end and wrist pin all run in aluminum, or the odd Chinese one uses ball bearings in the crank.
These heaters are more like candles than jet engines.. the fuel dribbles in and isn't injected with any force at all. It is not mechanically atomized and just flashes off on a hot surface, but I get what you are saying.
If I talked about using a carburetor in this vide, the plan for that is to use gasoline, not diesel.. I probably didn't make that clear.
My exhaust is always too hot to have issues with condensation. If I ever move past testing and get to a point where the heater is used to make heat (what a novel idea, haha) then I will consider scavenging all the heat form the exhaust that I can ... I have a few ideas.
Of course have catalytic converters been used on diesel engines. Especially on older diesel cars.
And you can definitely find catalytic converters on carbureted gas engines.
@@momowas Haha. I feel a feud coming on... I thought this to be true as well.
14:24 So. My understanding of this, is that when fuel rich vapor hits the catalyst, the catalyst heats up, without any flame, it is doing so from the fuel. This glowing red hot mesh is now your ignition point.
I was thinking the goal was to reduce emissions. I think I get it now. Did you explain that and I missed it? Or was it implied because it's about MOAR heat in the burn chamber, holding the heat, keeping it in the burn tube, not the exhaust. Enough heat to burn the waste oil, preheating to make vaporization easier.
It's all part of the larger scheme. I guess I get lost sometimes.
I wish I had the confidence and will to tear apart my burner often to burn waste oil. I don't use it enough really, the season has been so mild. We have 79F forecast tomorrow, I mowed my lawn earlier today. For better or worse, this has kept me on the scrap route for the waste oil. I've hoarded this waste and even hauled it in a move, it MUST find a purpose. Maybe I just plumb the heat outlet towards a tank of water (build a shell, insulation, yadda yadda) But skip the junk and go waste-oil in the diesel heater.
I think you figured out running it on diesel cleaned the chamber well enough pretty early on. Run waste oil, or a mix for however many hours, then switch to diesel for 4 hours to clean. If not doing tests, that's probably the simplest way to make use of the waste oil hoard and not Darwin myself mucking around with tin cans, vacuum motors, wicks, propane tanks and.. yeah..
I kinda played it fast and loose with this video explanation ... I figured the regulars would know that I was trying to get / keep heat in the chamber (so you were right there) and anyone new would be overwhelmed if I tried to explain it all.
Haha... yeah... I collected oil for ears once and then ended up hauling it to a depot in two trips ... the people there looked at me funny when I was leaving the weigh station on my way out ... I was 250 KG lighter than when I went in. Anyway... that's why I'm burning it now. I still have about 280 litres and considering that gets mixed with diesel and gas at 30% ... I've got a lot to go through.
Some people swear that they run 70/30 diesel/waste oil and don't have issues ... Others have told me they had had some problems. I'm not sure what the exact percent is where you can avoid problems, but some of it would come down to the crap in the oil and if it is synthetic etc.
Personally, if I were going to build a heater, I think I would use the first design in this video... Looks like it works amazing and you could put a heat exchanger or a water coil .... whatever floats your boat. Let me know if the link doesn't work.

Great show. Why not put the cat in the exhaust pipe instead of the burn chamber? And use a clean fuel before moving onto a mix?
Thanks. Keep up the good work 👍

I do use clean diesel to start and shut down the heater. I guess maybe I didn't point that out in this video.
Putting the catalytic converter in direct flame will destroy it as you've just found out. It should be mounted slightly more downstream. You may try putting it at the very end of the tube or even in the exhaust. Just by design, it will heat up to the temperature far exceeding the exhaust fumes anyway.
PS: You may really try just choking the exhaust at heat level 4. If you recall the first melted motor end cap, it worked well, before it melted.
Thanks for the comment. I want to try this again with a larger cat and with more spacing, for sure. I was under the impression that most cats are made of ceramic and can take intense heat... This one was some sort of thin metal.
The reason for placing it close to the vaporization area was to try to get more heat in that area. The issue with putting it further away is that the exhaust may come out clean, but the vaporization area will still run cool and plug up. My hope was that the cat would cause enough heat / restriction that it would heat the vaporization area and make it burn cleaner.
It has occurred to me that it could be a restriction to flow that made the heater work well with the motor end cap. The problem with choking the exhaust is that the heater will either not start or chole too much and actually run cooler. I think it where the restriction is is just as important as how much restriction there is.
@@loweredexpectations4927 The ceramic cats didn't last long on two stroke gas engines, so they came up with the metal cats for two stroke. More expensive, but they withstand the harsh two stroke conditions.
Catalytic converters for diesel cars usually are ceramic.
@@werner.x Right on... good to know. It seems as tho it is the metal itself that is failing in the cat that I used, ... I'm assuming that the failure mode of a ceramic cat would be that it got plugged or just used up all of its catalyst ... but that's just a guess.
@@loweredexpectations4927 The normal failure point of a gasoline catalytic converter is the point, when the catlytic metals are worn off to a degree, emission tests are no longer passable.
The extrordinary failures of a gasoline cat are broken ceramic due to explosions or molten ceramic due to lean running.
The normal way, a diesel cat is failing, is clogging.
This can be cleaned out, but burns off during a highway run, when the underlying problem got fixed.
The other thing, used up catalytic material, is something, at least here in Germany, can not be detected during emission inspection.
Shattered ceramic isn't to be expected in Diesels.
Although there are some emission level 4 upgraded vehicles which retrofit cat-particulate filter combos crumbling away regularly. I assume, this happens, when a clogging filter is rising the flow resistance and so, the cat section gets too hot, but that's only my guess.
Because these vehicles need a regular added catalyst into the fuel tank and if you forget that, the diesel particulate filter rarely ever reaches freeburning temperatures. Also, nothing monitors the ash load in retrofit filters.
But car won't go in limp mode, because there is no computer to run the engine. Emission upgraded VW Vanagon Turbodiesel have this problem here, for instance.
@@werner.x I don't think my heater would pass an emissions test 🤣
From all of what you wrote, what I'm hearing is that I need to stop babying my heater and to more highway runs.... and stay away from emissions testing depots ... Got it 🤟
I've watched most of these videos, many out of order. Have you tried routing the fuel line in a way where it'll get heated before hitting the burn chamber? It should help make it burn cleaner, especially with waste oil.
Hey, thanks for the comment !
I have actually tried this. Not in the classic way that most people have recommended (copper pipe around the exhaust) but with a pipe running through the exchanger fins. This limits the line heat to 230C (about) so it's not nearly as dangerous.
It seemed to help some... the fuel was entering the chamber at around 100C. I did have some issues with the fuel feeding erratically, as impurities (gasoline and moisture) vaporized inside of the line.
@@loweredexpectations4927 Ahh, I remember that now. Oops.
@@DonziGT230 Haha... it's all good. I've done so many videos it's hard for me to keep track of what I have and haven't done.
My guess is oil or soot splashed onto the catalytic converter, got turned into ash and then overheated it to the point of melting. A car engine that burns too much oil will destroy its catalytic converter in a similar manner too.
Seems like an accurate assessment.
E-mail the oil-lab-test company if they are willing to give you a few tests and an affiliate link.
To find out how many grams of solid waste particles, every liter of your waste oil carries.
That is a really good idea... That would be handy information for anyone who is trying to burn waste oil. I'll add that to my long list of things I need to do.
I've been watching since the first video on this channel and I love all the experiments! I'm not so sure the carburetor is going to work so well feel like there isn't enough draw in the intake to actually help atomize in the venturi but I'm stoked to see what happens
PS how about a quick video on that little car you have sitting back there I'm intrigued haha
I'm also concerned that there won't be enough flow. I will need to have it in the fastest setting for sure, and even then it may not work. I'm also worried about backfiring ... haha.
I could make a video about my car ... I'm actually in a financial tough spot and have been trying to sell it so maybe someone will see the video and buy it, haha.
@@loweredexpectations4927
It's funny, how people get their ideas.
There is not a single carburator oil burning engine in this world and yet, after more than100 years of challenging research, there's a gasoline carburator asked to try out. We'll see.
@@werner.x Man... This Joel Arseneault guy is getting out of hand ... I'm going to have to block him.
This could be a giant disaster and just a few clips inserted into another video if it turns out really bad, but here's to hoping I can make it work. It may need some sort of one way valve or something to stop it from backfiring, but also a one way valve would mean that pressure only has one way out and that could make the BANG even bigger if / when it backfires.
@@loweredexpectations4927I'd just try it without valves.
I wouldn't expect backfiring, as long as there is not much gasoline involved.
@@werner.x Oh.... there will be gasoline involved.... I guess I left that part out. The fuel used needs to be something that will evaporate / atomize easily or it will condense and run back out the inlet and build up on the fan. In the intro, when I mentioned it, I said "start it up on diesel" , but left out the "switch it to gas" part.
I was hoping this would work but sadly it didn’t . Maybe you need a flux capacitor to sort it all out 😂
I need a bigger catalytic converter... Not sure what this one was made out of, but the material was some sort of metal and not a ceramic.
How about the catalytic converter down at the exhaust hole just for the pipe hooks on to go outside
I guess I didn't make it clear in this video, but the idea of running the cat where I did was to try to get the vaporization area to heat up and flash the oil off. I made a few videos about this leading up to this one.
Putting the cat further down stream would work to clean up the smoke, but it would do nothing to heat up the area where the oil comes in.
And waste oil will probably be very hard on a catalytic converter
Yes, any oil is going to be very hard on a cat. This was a fun experiment and I learned a few things from it, but I never expected this to be a long term solution, especially with that small cat.
Similar to the carb venturi, could you make a burn chamber as a venturi? Pull the fuel in the choked area of the venturi?
That's an interesting idea.
Please correct me if I'm wrong: Isn't there something about catalytic converters to be at some distance from the engine to not get fuel into them, also I've read to not pull start cars because of unburned fuel getting into the catalytic converter and destroying them. Maybe unburned oil got into it? At what temperature should a catalytic converter run?
I don't know about a distance being recommended. Cars usually have two, one close to the engine and one further away. They don't work until they are hot so a lot of modern cars will actually dump extra fuel out to get the cat warmed up, when the engine starts.
Oil is a bad idea for sure, and the catalyst does get used up, so it is a good idea to run as clean as possible before going into the cat. OIl and additives can plug your cat up and cause them to fail before they are used up, so it is best to avoid.
In my series of videos on trying to burn oil, I have found that the oil is not getting hot enough. I have also found that if I can get the chamber really hot, then it burns really clean. The hope (other than entertainment) was that the catalytic converter would build up enough heat that the oil would start to burn clean.
Distance is car dependent. Start temperature range for a catalytic converter is 250 - 280°C. This has to be delivered by the engine.
Operating temperatures are 400 to 600°C, this is fired by reaction and by the amount of extra fuel, a car with three way catalylic converter consumes, compared to good running engines without emission control.
Ceramic starts melting around 800°C. This will immediatelly restrict airflow irreversibly.
400°C is also the starting temperature for a diesel particulate filter freeburning, end temperature in full burn is 600°C, self extinguishing, and then dropping back to 400°C max. operating temperature under full load conditions.
So, a cat in a gas car operates at higher average temperatures than a diesel cat. A diesel cat also reduces other products, they target only NOx, afaik.
No higher temperatures than 600°C occur in normal operation, whatsoever.
So, if you place these expensive parts wrong, it gets costly.
@@werner.x I had no idea that ceramic melted at those temperatures... I assumed it was much higher. These heater videos have taught me so much. When it comes to running catalysts on automobiles, it sounds like a complete pain in the ass ! Haha... I'm glad there are engineers out there figuring this stuff out so guys like me can come along and ruin it 🤣
@@loweredexpectations4927
There is ceramic with way higher melting temperatures. It's just, that the material only needs to fit the case. With millions of built items costs for the manufacturer add up quickly.
@@werner.x That makes sense.
A carburetor works by using the lower pressure created by the piston moving down. How would a diesel heater create this lower pressure zone?
It is a gamble on if it will work... The heater uses a fan to draw air into the heater... All the carburetor needs is air flow through it. We shall see if it is enough.
Direct flame impingement on a catalytic converter matrix will destroy it. Good try, though. Might be more effective to have the exhaust flow through the cat since it's hot enough to convert and burn the hydrocarbons.
Yeah, this would likely last for quite a while if I just used it on the exhaust. However, the main goal of all of this, other than amusement, was to try to get more heat to stay in the vaporization are where the fuel comes in. It has a tendency to burn cool and plug up with carbon.
@@loweredexpectations4927 Kudos for experimenting! I am running my unit on red diesel. The unit is clamped to the top of my wood stove and exhausts into a 3/4''npt hole I put in the stove side. The top of the stove gets warm and I put the big aftermarket muffler on with a heat powered fan sitting on top to move air. The draft takes the gasses out through the chimney.
The test started 3 months ago. I ran 12-14 hours a day until last week when the cold set in again. After running 24/7 on heat setting 3 and run up to setting 6 for 30 min a day in morning and evening, the warmth keeps the living room warm day and night. The heat finds its way upstairs as well. The cost is far cheaper than running the central natural gas furnace. I did not use the central furnace at all in January and February. I have a 14 foot vaulted ceiling and keep the ceiling fan on low 24/7. Keep's ma's couch area 68-74F and the cat likes it, too.
My major improvement was to add a 12 volt LED light up by the fuel pump, lengthen the fuel level slots in the housing to the very top, and added a fuel filter ahead of the pump. I can see the fuel level from 30 feet away. I refuel twice a day with a 5 liter ''No Spill'' push button jug. Best invention ever!
Keep up the good work

Hey Joel, finally got my heater installed in my workshop this weekend. Works great, especially with all the snow we got. Quick question, how did you figure out how to pair the remote? I've watched some other people's videos but it their instructions didn't seem to work. Cheers.
I have two controllers. One came paired, and the other one that I got from allay express, I tried to pair 3-4 times and gave up.
What controller do you have on the heater and what color are the digits ?
@@loweredexpectations4927 blue controller, with blue digits. black remote with display.
@@loweredexpectations4927 woohoo, I figured it out. Press and hold the power button and right arrow button at the same time on the display until "OC 1" is displayed, then press the up arrow button on the remote. It will say "wait" then will connect. Worked for me. Not sure if it will work on yours depending on the model
@@PUBHEAD1 Awesome. I'm glad you sorted it out !! Sorry I wasn't able to help. Oh... wow... OC1 popped up on my screen once and I was like "that's an error code I haven't seen before..." lol
Hey Joel, what would happen if you had 2 fuel pumps running into the glow plug, weld another fuel line in situ with the other fuel line.
I'm not 100% sure what the end goal would be ? To double the amount of fuel delivered ?
Still waiting on the bacon grease.
I filtered it and ran it through its first gelatin cleaning last evening.
@@loweredexpectations4927 🤣
So what about about burn chamber lined with steel mesh? :) kinda like starter chamber but through the burn tube
The guy from hobbychanel germany has been trying this with some other mods... The "trouble" is that, for this to work, the fuel needs to come in contact with the mesh, so it needs to go outside of the vaporization area. This is better than nothing, but being against the walls of the tube means that it won't mix with the air as well. The idea of the reduction ring, I believe, is to mix the vaporized fuel with the air so it burns thoroughly.
@@loweredexpectations4927 yes, but you don't sometimes think that all that burnt gunk that builds up in the burn chamber is actually unburnt fuel that doesn't get vaporised and like a big water drop or stalactite in the caves simply builds up kinda like 😂 wait something is coming.. 😂 Like glacier forms there.. And i would try extra mesh strip lets say out from start area towards burn tube.. Maybe thats all u need to vapourise all of that leftover unburnt fuel.
@@sisisduo Haha... yeah... it is possible.
sooo with the carb you won't use it to inject fuel, i hope.
just to throttle it?
because the burn chamber is not air-thight so it would just backfire and set everything on fire
👁👄👁
If the Venturi effect of the carburetor actually atomizes the thick oil, I’ll be surprised. I don’t think there will be enough airflow. If it does, boom 💥
Gasoline vaporizes/evaporates well in airflow, it’s a distillate. Oils not so much.
The idea is to use it as it would be on an engine... to deliver fuel. I'm not sure if it will backfire, but if it does it will probably flame out. I will prepare for the worst and hope for the best.
It's looking like someone is not going to be running waste oil for a winter with a diesel heater.
I would advise against it.
Why not install the cat at the exhaust pipe?
The reason for the cat being so close was to try to use some of the heat from it to help the oil burn cleaner. The area where the oil comes in tends to only run about 180C and it should be 250 ish to flash off the oil. I have had several people ask about this, so I should have explained better.
A catalytic converter this small can be effective?
This cat was designed for a weed trimmer, to stop oil from running out the exhaust when used at low throttle positions. It is effective for that, or for a really small engine. You need a much larger cat for a much larger engine.
It looks like ash and soot?
Yes, nasty.
4:20 I have so many questions. First: WHERE does one find a small catalytic converter? I tried searching ebay before for any small engine cat, IDK if I'm using the wrong terms, but I could not find anything. I searched weed trimmer catalytic converter on google and aside from this video as the first result, it's all blog/forum topics from the early 2000's complaining about a law requiring them on lawn equipment. I have never seen a cat on any mower or trimmer, even my riding mowers don't have them. Is this a CA thing? CAli, CAnadia, and their CAts.
Aside from that though, I am really confused why it's going in the burn chamber. it should be in the exhaust stream, no? Very confuzzled.
I thought about a carb before, never mentioned it because it seemed so obvious. Indeed, why?? did it take this long? And of course I'm thinking once more if you can run the carb setup with propane or city gas.
They are not used on a lot of stuff. This one came from a ECHO trimmer. You would likely be better off buying one from a car in a scrap yard and cutting it open... then using a chunk of it. That's what I plan to do if I do it again.
ECHO put them on their trimmers as people complained about them dripping oil out the muffler... It is not at all common.
If I put it on the outlet of the chamber, or even on the exhaust, the it would likely last much longer and it may work for clearing up smoke. However, the reason why I used it, was in hopes that the catalyzing would make enough heat to warm up the fuel and make it burn clean instead of clogging up.
Yeah... running a carb is just a silly experiment to see if it will work and more likely, how big of a backfire it will make. It is not at all practical, but if it works it would be neat.
put a car cat on the exhaust of this thing
🤟
@@loweredexpectations4927 Just make sure you're EGT getting to the cat is at least 400C.. That's about the point they start working at.
@@cheetor5923 Yeah... that's tricky to calculate, but I assume it may get too hot.
How do I partner with VEVOR i want free stuff
Buy some Vevor products and make some videos. If your videos do well they will contact you.
That's what I did, although, my plan wasn't to partner with them.
Cats are used in an exhaust situation not in a burn zone in you overheat it it’s useless
True... The reason for placing it in this location was more or less an attempt to trap heat around the burn area. It probably wasn't explained very well, or at all, but this was a result of a bunch of other testing that seemed to show the temperatures where the fuel was entering was way too low.
There is a reason diesel engines don't run on carbs. I will let you figure out why
Everyone assuming that I'm going to try running diesel ... I guess I should have clarified... I started to say it, and then got side tracked somehow. The idea is to start it on diesel with the normal set up and then switch to gas in the carb.
I have run a few gas engines on diesel and they don't like it... not just because of the carburetors, but yeah... not ideal, haha.
@@loweredexpectations4927 ah I see that will be a fun test. I wonder how that blower will handle it. That will be a fun one. I've gotten to fix a few mowers people have tried running on diesel👍
@@lanceulbrich6249 Haha... Yeah... When I worked for Sears we got it every now and then. People would never admit that they had put diesel in, so I'd just say "I guess it must be gas". I'd pretend I didn't' know what was wrong and force them to run using quick start... You have to use the choke and or prime them a lot to keep them going, at first, but once they get hot they will actually run. I have a video on my other channel of a snowblower running on diesel and it is blowing smoke rings, haha.
@@loweredexpectations4927 yeah they DNT like it very much tho and needs to have at least some gas in it. Used to be a diesel mechanic we had one of the kids that mowed the lawn do it a few times. We did always have some diesel in a gallon red can to prime the fuel systems if we had to change a fuel filter on the go.the younger guys didn't usually know any better happened a few times.
@@lanceulbrich6249 I've been tempted for a few years now to try to see what percent I can run in my jetski engine (2 stroke) ... It's pretty low on my list of things I need to do tho, haha.
If you get an automotive cat and remove the Honey comb you can chip away at it to make it fit the chamber. Won't work but there you go
Yeah... I want to do this, just to see what will happen. I know that it will clog up pretty quickly, but I would like to see what happens before it does, haha.
@@loweredexpectations4927 maybe if you run jet fuel it'll clog less.
