If pieces are popping off that means it has compression
yeah
No shit nut head

@@outdoorshenanigans849 this reply section tho🤣😂
Needs Proper intake, bigger exhaust, super glue or other renforcement. Good idea about the shorter stroke.
Heavier and more balanced flywheel would probably really help too. a couple bolts taped together doesn't do well for that lol
@@SpeedyGwen Lego technic won't help much. They're holding it together with chicken wire already and it's blowing that apart - No way a rounded piece of plastic would do any better.
It need timing that’s all
0:35 look at this in slowmo you will see what I mean
Yes. No. Yes. mabye..
@@SpeedyGwen welp anything that doesn't work always needs a chage
you need an air intake, gas wont combist without it
U got that
U got that
U got that
U got that
U got that
Plz keep it going Im interested of too of my favorite thing
YEAH! SECOND VERSION!!! one year later, thanks for uploading
Also if it works right it will only run for a short amount of time before plastic welds itself together.
But at least we get to witness those few seconds of sweet success
The timing is absolutely wrong
Why is it sparking when the piston is nearly at the lowest point?
It needs to spark when the piston ist al the way up at the highest point
Otherwise where should the piston go when it fires
0:35 look at this in slowmo and you will se what I mean
The engine is basically working against it self that’s why you only get one combustion and the engine falling apart
yeah
Huh I see that now. Well no wonder it failed to run aside from fuel air ratio
where is the air going to get i to the cylinder? or do you think gasoline combusts in a vacuum?
wouter calcoen LEGO’s aren’t air tight
@@technopanda1018 well if it iisnt air tight,then it will have a compression problem
DevilZ Gaming its LEGO
@@technopanda1018 i Know What The Heck Is That I Know Is Lego If Isnt Air tight The Compression Will Be Zero Meaning No Combustion 5 Main Things Engine Needs To Start And Stay Running
-Air
-Fuel
-Spark
-Compression
-Timing
@@technopanda1018 pieces Were Falling Of It Has Compression
The compression is there but not significantly completely there because the top popped off with the force of the explosion but it does have a little to do with it. The fuel might need to be more rich and you will have to oil every piece of lego under the actual piston.
Wow, this looks way better than the previous design! It works even better too.
YOO BRO!!! Didn't know you watch this channel! How's it going? Btw i am on my brand new gslaxy s9+
@@nascarsimracing1 Ok
Just need the kraggle, everything will be awesome
Taco Tuesday
Been waiting for this for a long time!
1. U dont have much air entering the cylinder, more air the better
2. U need a carburetor of some sort, fuel has to be atomized to burn properly in a engine
3. Use rc nitro fuel, it burns quicker, faster, hotter
4. Compression, u have no piston rings at all, meaning no compression, not good
5. U about have all the principles of a working engine after that, i think u should stick with v2 because thats a good chance of running, just make the seal tighter for better compression👍🏼
Good luck keep us updated super cool build🤙🏽
I agree with everything exept 5th.. he will probably try the v2 if the v3 doesnt work
Will it not melt?
@@nicolaspaglione of course it will melt but atleast it woukd run for a few seconds
Demo wonder if some non thermoplastic lego parts would do the trick?
Love the progress. Keep it up!
Yea i was waiting for sooo long to see the lego 2 stroke again!
Same😂
I always wondered if there’d be a part 2. Glad there is
You need to have an fog of gasoline not twostrokes should get a on part gasoline to 14 parts of oxygen!
Finally I have been waiting for ever
Very nice, thx for this.
Put on some oil
Find a good air fuel ratio
Make a stronger structure by adding more pieces or gluing them.
Would love to see this working. Keep it up!
One of the problems we had the oil would make the compression too high and proved to be much of a hinderance rather than a benefit. But this time we are gonna use 0W oil
Yeah and instead of lego take aluminium...
lol i was waiting for this for months
It will definitely melt. How about a pneumatic engine made out of those actual Technic cylinder parts? Smallest Lego pneumatic engine.
MrRedstone pepole allready made those small pneumatic engine
Bro this is cool as hell I would have ever thought u could even get Lego to compress enough to fire hell yea
I am so hyped for the next video if you guys pull this off you will probably earn alot of views and subscribers! and maybe in the guinnes world record book
I hope so as well
Use nitro fuel and make a carburetor and have the fuel tank above the engine so gravity will feed the fuel into the engine
Also try a glow plug
@@snarkspark9302 nah dude nitro fuel requires a high compression engine and thats hard to make with lego
try with ethanol fuel
JB Weld the pieces together
I thought I saw it sparked while the piston was going up. I probably have no idea what I’m talking about, but I think maybe the ignition should be delayed a little more..
Here is a couple of suggestions:
1. Make almost the entire thing out of technic, technic have more strength when together, that are easier to cover in tape, and are easier to get a better seal.
2. Stop using flex glue (If you are using it), J-B weld is stronger, cheaper, and overall better than flex glue, also try Loctite.
3. You need to use a better fuel, maybe fuel that has a little easier combustion with just enough power to push the piston down.
4. Find a good oil, with some oil you can further reduce friction, and maybe even make a better seal.
5. Keep trying. Just keep trying. Eventually you will find a design that works.
And that concludes this. Feel free to reply if you have questions. I will try to answer them. (And trust the things I said, I know A L O T about E N G I N E S.)
Wooooww subscribed
This is so cool
Holy crap I wish I could get my hands on custom engines like that B series- LEGO should actually make those for special edition sets. If I had the bricks and could get any custom engine, I would build an RC replica of my dream car, the CD5 Accord, with an F22B1 under the hood
Looking Good Hope it Works.
Plz do more of dose Video so i love it
Nice
Nice house
Fucking finally! I've been waiting for this
For starting a regular engine you need much higher rpm, maybe try to connect the engine to a drill and try to get frequent explosions, than try tonstwrt it. Also use a much stronger design and superglue so the pressure is cept and the engine doesn't destruct while spinning it.
Nicee
This is interesting as f*** I want to see more
I think if you make I4 engine from metal it would be more interesting 👍👍👍nice video keep it up
Ridders 4 stroke here on youtube doesn't use injection, the air intake has a small gas tank in it that the air passes over and picks up enough gas for combustion, probably runs lean, but it works. Not sure if it'll work on 2 strokes as I don't know too much about them
Try a bigger flywheel ant check timing and fuel-air mixture
I suppose a crack house is the perfect fit for trying something as crazy as making an internal combustion engine out of legos.
me after last one talking to myself:
What are you going to do?
Wait.
I have a similar but bigger design, but im still working on it tho and i think the spark is just right i just need to glue it together proporly and i should have compression like yours, and the ignition system is really different from yours
you can use an m motor to automate it
Love your work guys.
How does the ignition system work???
Just an arm that open/closes high voltage circuit of a fly squatter
@@madbrick923 So do you stick a metal piece into the chamber for the spark to happen?
The Pinnacle of safety
I think one problem is that it’s made of Legos and the compression just blows it apart
Bigger exhaust ports!!!
That honda b16 engine 👌👌👌 i want one
Use nitro fuel so it doesn't take to long to burn
This is the coolest thing on uoutube get itt
Use bearings and make the fly whel with pennys its looks not heavy enough
But awesome idea
I would try to make an exhaust valve or something and try to ad an extra full rotation before it fires again make the stroke even shorter
Finally!!!!
Finally!!
A 2 stroke wont run without a crank case. The piston actually pushes the air/fuel into the cylinder when it goes down. If you want to run without a crank case you need to compress the air fuel mixture pre going into the engine. Like a 2 stroke detroit diesel. I may be wrong but i have never seen an working 2 stroke without any of the two.
You should use car ignition coil, its not that complicated to wire up and unlike this thing will produce the spark almost instantaneously
Can you use an electric drill or something as a starter motor that you can uncouple once engine is running?
Yes we had a ratchet type drill in the previous version but we wanted this to all be done by hand
you could lubricate the plastic in order to lubricate the engine like actual engines do
JB weld the legoos!
If you’re going with a single cylinder design you need a counter weight on the crankshaft as there’s no other piston pushing it back up. Obviously you need this to keep the engine turning but also to compress the air/fuel mixture speaking of which you need to come up with some efficient and effective fuel injection system as it looks like sometimes it’s misfiring meaning it’s probably either getting too much fuel or not enough air easiest option would be a carb but I honestly don’t know how you’d manage to make one out of Lego though I’m sure with enough Lego pieces and a good design it might work. But then once it’s finally combusting by itself you’ve got issues like lubrication and cooling which is a big issue since Lego has a much lower heat tolerance and lower melting point if it gets hot enough the plastic could literally start to melt and fuse together.
I don’t know if you have fixed it but in the first test of the video it seemed like you had the problem, that your ignition timing was off.
What I mean by that is that your engine fired while the piston was going from bottom dead center to top dead center and so the piston had to fight against the pressure of the burning fuel resulting in your engine to get separated as the force of piston vs “explosion” was stronger than the force holding the engine together.
The ignition timing is also set by the type of fuel you use and more exactly the time in which the burning fuel starts to make a significant change in the cylinder pressure.
Most common ignition point is when the piston has nearly reached the top dead center. By the time the piston has reached top dead center, the pressure of the burning fuel is high enough to force the piston down again.
Because you have a pretty slow combustion or “explosion” (mainly because of little compression and bad combustion chamber design and other small things) as well as a fairly heavy piston (at least I guess so) you can set your ignition timing quite early.
I really hope you read this and finish this awesome project!
You know they do make steel legos. Probably be alot more stable and wont melt as easy lol.
You guys need a Caborator so there is vapor to burn not just fuel and there needs to be a good amount of compression.
You need to time ut with intake and exhaust valves of some sort because igniting pure fuel in a closed cylinder is obviously gonna blow the cylinder apart
Definitely want more , I am going to try casting Lego this summer - Lego will melt , aluminium Lego blocks ( or steel ) could work - just a metal head and the rest could be plastics , this would solve compression and will have more power! , Just an idea ( pls reply)
Yes that would be awesome! But it’s really important to have the correct fuel ratio. The biggest problem for us is how to mix fuel and vaporize it. But if it was steel, you could probably make it run, not good but at least run
@@madbrick923 thx, plan to experiment during summer
What’s the song used?
How can you live in that place?
Maybe try a 2 stroke mix with oil?
That’s a nice house you got there buddy. How much did it cost? It looks expensive
Disis zabroshka
U gotta nice house
I’m having a bring your own crack party
A solid flywheel would be far better otherwise the engine is more likely to fire in reverse also if low compression becomes an issue line the cylinder with a thin film of oil it will at least help fora few revolutions
You need a intake because engines spray the gas like a spray bottle along with air and that vapor is explosive and then you light it so your engine will not work due to the fact the gas is sitting on the cylinder and is not a vapor so it's not explosive enough so you have to make a intake system or pump in a vapor or you gotta use a different fuel
Use propane its much easier to deal with when air/fuel ratios are wrong. You should also look into diesel 2 strokes as that dont suck air in they blow it in. Conventional engine needs to draw air in.
It needs to be sealed for proper compression use sylcone or some thing
Fire needs air, so your engine has no air so no fire unless your compression is out of the house crazy
You may need something like a counter weight to help the shaft pass its "dead point". I don't really know what are you trying to do. Just trying to give some recommend. :p
Look you need to make the combustion chamber way smaller
Don't use the electric fly swater cus that uses a electric pulse and you want a power source that is more stable
i think it needs to have a smaller piston because the explosion is too big
Metal legos❌️
Plastic legos ✅️
This can works only with lego carburetor
Use some fat or Teflon spray against the friction
Did you even have an exhaust
Where is the fly wheel it help the piston go back up
It might be sparking too soon.
Just get the mixture right if it’s a two stroke put some castor 927 I here probably a 40 to 1 mixture but that’s for u to figure oit
Good luck with other trys
You need an compression, this engine doesn't have any compression
It does if pieces are popping off
Probably just needs better timing and spark
Make a Lego car with a engine and a gearbox!
I clicked cause of the thumbnail
You need to super glue the bricks down
What’s the displacement? Also I’m building something similar. Want to have a race to see who can get theirs running first?
4x4 stud
Does it even have compression? Also have you tried to turn over a real engine by hand?
Thats literally how engines used to be started
What engine is at miniature?
Where is the air supply?????
if only it had a counter wieght on the crank, it wouldve started up I bet ya
You’re missing an alternator
A Normal l motor should start it right up
Plus you need to have a quarter turn
For quicker combustion
