- We mainly worked on the electronic fuel injected test engine. The fuel injection system will be fitted on the supermileage engine once we get all the kinks worked out. Custom electronic fuel injections systems this small tend to be pretty hard to work with. We also did a few repairs on the body.

I'm part of the super consumption club, Iv'e managed to get my LS3 down to 6mpg
Thee Adjudicator it's not about the miles a gallon it's the smiles per gallon
I wanna be in the super consumption club! my small block is about 8mpg!
808 Tait lol try 5 mph in a 7.4 liter Pontiac v8
Mpg*
Conidro I love those engines! 455 right? fuel economy means nothing if you're having fun every time you drive!!
Put a eBay turbo kit and slam it on tarmacs and daily it
ILikeFryz lol the haggard garage way right here
Next video: the ebay turbo focked me!!
ILikeFryz the nerds reading this comment won't have a clue what you guys are referring to…while I'm over here laughing my ass off Lmao
I was not expecting to see this here
Cam Currier haha fancy seeing you here
A lot of this is above my head! I'm an old school hot rodder! But I love what y'all are accomplishing with your studies and work. Hats off to all of you!
Ayyy! I remember watching your videos 6 years ago and wanting to start a youtube channel. Glad you're doing well in college. I was going to go to Penn State but ended up going to OSU. I'll definitely stay tuned
we need vtec up in that bitch
Rafael Santana its a meme, aka not meant to be taken seriusly
I've been a racer, machinist, welder, designer and fabricator my entire life so I really understand the engineering part of it. I have always been very interested in projects like this and doing anything different. I have also worked in the TV and film industry for many years. Now I'm mostly doing video work again but for myself and only what I want to do, things like social media and TV commercials, filming plays, weddings, training videos, music videos etc. I'd love to talk to you guys about maybe doing a short documentary about your build leading up to and through the competition.
I expected to find smarter people in the comments section of a video like this. They must be people blowing in from crackpot free energy, boost your fuel efficiency with this trick oil companies don't want you to know videos...
dont forget the cold air intake folks
Lawrence Lentini it's fine, get a electric, better in EVERY way.
Sterling engines can achieve 50% efficiency converting heat into mechanical energy.
SUPER COOL PROJECT 👍👍👍. Like these type of video's very much, so please show more 🙏🙏🙏
oh man, I love those cut-away engines! So cool!
Lol, so much fun things in that engine, B&S, carbon fiber pushrods its amazing!
Would love to see some more of this.
This is great I wish I was part of a group like this pure awesomeness please keep posting
Hey, I know that this is an older video but this really peaked my interest because the project that you guys are working on is essentially many of my main interests combined into one machine, I have also been considering going to Penn State university when I am out of highschool and would like to know what you're majoring in.
really good stuff!!! yeah more more more. :) it's All ways fun. to fallow a project. ~Russ
Very cool dude, would love to see more of this soon.
Pete.
Excellent! I will stay tuned.
That‘s cool as hell 👍 keep up the great work guys
Very nice fella. Keep up the great work too.
He looks like the dude from "that 70's show" XD
Just needs 'Aviator Sunnies'. :)
try about 3 in a cadillac 500
Yeah, this would be really interesting to hear more about. I have a small engine missing a carb that I was almost considering doing fuel injection on, and if I ever have the chance then duplicating this would be interesting for a efficient generator engine.
love to see it weekly !
love those engine videos
Man.. Wish I had something like that in my university, that looked pretty awesome to be a part of
IrishSkruffles get some engineering students together and start a supermillage club!
Great video. Really informative. I would love to see a break down of that engine.
i like how this was made using a predator engine. great job guys
21:1 compression ratio that's massive for SI. Maybe the combustion chamber is long and skinny enough at TDC to cool the fuel and resist detonation?
+ghetto bikelife the combustible chamber is pretty long. When the engine heats up enough we do have problems with detonating. The engine never heats up much in the competition because it is only run for 10 or 15 seconds at a time. When testing we can turn the ignition off once it's gotten warm and it will diesel and continue to run. Choke comes in handy then lol
Sounds like a SCCI engine to me.
if its direct injected they can diesel it and control detonatiom
You can have a high compression ratio and a lot of advance on the timing if you don't open the throttle very far. Did he say they were running at 4300 rpm and 22 mph during the contest? Seems like a high rpm for milage.
The mean piston speed is actually on the low end of the spectrum due to the shorter briggs crank. Peak efficiency even at full throttle maxes at ~4k rpm.
Cool glimpse
If valve float is keeping you from optimum RPM, have you tried stiffer springs or lighter valves?
the heavier the springs, the more power is being wasted in each cycle trying to open the valves, reducing available work being produced, basically, fuel wasted due to more work being used to open the valves. To prevent valve float they could come up with a creative solution yes, but I wouldn't see why they need to rev the engine higher as the higher it revs the more fuel it uses. I would too, not want to rev a motor with 20sum:1 compression as I feel that the whole room would become rod territory :D
@@unitytwins6652 ..and? You probably achieve more power when you reach higher rpm so it won't actually matter
If they would have gone to an overhead cam, they could have eliminated the mass of those pushrods and possibly the rocker arms using a very light timing belt. That would have reduced frictional losses and given it a higher RPM before valve float using those same springs...
Told you I'd check some later videos. I forgot Behrend had a supermileage team. Good luck. For the Glory.
Wow ! Thank you for allowing us to see the club. I am amazed and congratulate at the MPG achieved. I am also wondering how this modified power unit compares to say a standard consumer portable electric generator in terms of it's efficiency ?
Love your video
That's really cool
Thank you for the video.
This is awesome
Awesome choice to use a megasquirt for the fuel injection
Impressive guys! Keep it up!
Cool vid man
That's a pretty cool and insightful look at what they are doing. I wonder, is that B&S engine a platform requirement for a broader competition class? Is there a competitive low milage race for this?
Smart indeed well done 👍
this is pretty cool stuff.
I wish i had the opportunity to go to a school like yours when i was a kid
I might have a cxouple of suggestions that will improve your setup. My brother and his friend made a headgasket with four sets of platinum points equally mounted around the cylinder. It was layered in between the gasket material like a circuit board. So instead of firing from the spark plug it fired from each set of points. The platinum points had no place to hold any carbon build up so would not foul out like a spark plug. and firing the gas mixture with four sets of spark burned the fuel vapor quicker and more completely.(old airplanes had two sparkplugs per cylinder)
Giving an increase of power with less fuel consumtion and less emissions. My idea to add to this is to reduce fuel droplet size thus increasing surface area of the fuel by using an ultrasonic mister which instantly vaporizes a drop of liquid to a finer mist than a carburator is capable of. This should also increase power while decreasing consumption andEmmisions. The reason you do not see this gasket method of spark on the market now is a sparkplug company bought their patent. Their was a drawback to the design they had not worked out at the time and that was that the gasket was thicker and you had to torque it down just right or it would blow the gasket. But this was 40 years ago and we have much better materials to work with now. I really hope you read this or anyone else . It could be an easy add on for cars well worth the cost for the increased economy and decrease of emmisions. Hopefully give a little more time for the transition to the totally electric cars that are coming. Jake The Snake Was interested in the gasket for his race cars as it would have been a huge advantage. So if you need an investor you might want to try him. It also goes to show how money trumps humanityand that big corporations (Firestone) are more concerned with the bottom line than reducing polution to save mankind. We really need to institute a crimes against humanity law for people like that and Big Pharma who suppress or overprice discoveries that benefit life.. Please send a comment should you read this. I like to think I am at least trying yo help.
very nice !
Good Job :)
great stuff!!
very nice engine, i would love to have that.
loved the "lots of standard stuff"
I was proud of my 20mpg in my camaro with longtubes, full 3in exhaust and unturned.
Good old TunerStudio... By the way, what ECU is that?
It reminds me about MegaSquirt MS1 a bit.
wish i could go to school here. badass
Nice man! I was in a SEM team for over 3 years, it was one of the most exciting things I did!
To get over 2500mpg really requires creative engineering. At that point the smallest things start to matter. Things like viscous bearing friction, rotating body energy losses, thermal material properties, resonance etc. Even finding a way to keep the engine at operating temp because of the efficiency being to high to keep itself hot.
Be prepared to learn a lot ;-)
Yeah! It is incredible. Honestly I don't think their steering alignment is very good. Might be something I want to work on.
I'm sure you could do a great job on that. Maybe it's nice to take us trough the process of doing research, designing, manufacturing, testing and reviewing the results. You can show young engineers why these projects are so valuable. I'm sad I didn't document those things when I was working on it.
Yeah I can definitely do that if I decide to redesign the steering.
I need to make me one of those that's pretty cool man
Regarding the engine:
Dieseling will be caused not just by compression and engine temperature, but also by hot spots in the combustion chamber, in particular the valves and the spark plug. Both can be modified to reduce hot spots dramatically
Carburettor/injection system - A constant velocity style carburettor (not what you have there) can be modified to have superior vaporisation to any other carburettor, in addition to that you could run a heated manifold, this would improve vaporisation even further. You still don't get the control that EFI offers, but you get superior vaporisation (which affects burn speed and efficiency, a LOT). Running EFI with some form of fuel or manifold heating would offer the best of everything. Also, if you are running unheated port fuel injection, injection timing matters a lot.
Variable compression - Varying the compression ratio in this way is not ideal, depending on the combustion chamber shape. If you have a combustion chamber that runs large squish pads (area where the piston almost touches the head) it vastly reduces the effect of said squish pads. The effect of the squish pads is to increase combustion chamber turbulence, which reduces detonation and improves burn speed & efficiency, so you definitely want this in your combustion chamber design. I have no variable compression solution for you, but you should know that compression isn't the only thing changed by by those shims.
Feel free to message me for any questions you have, I would love to have input into a competition like this
Is that Megasquirt? Awesome that you managed to achieve such high compression ratio too
Note the glaring lack of gas vapour bubblers. :)
I think it's terrific that you've found this club that ties into so many of your long standing pursuits!
What sort of problems are being encountered with the small fuel injection system? Lack of fuel pressure -> inefficient nebulization/long duration injector cycle? Low-to-non-exsistent intake vacuum?
Hahaha yep! No HHO system either! :P
IDK about fuel pressure. Higher pressure would probably atomize the fuel better. So far this is the best I have seen this engine run fuel injected. So we are making progress. I wonder if injector cycle duration might be a problem when we install it on the smaller displacement engine.
Well, "injector" is a slight misnomer; it functions more like a gate, as it doesn't actually supply any injection pressure or metering. a pulse of current opens the injector for the duration of the signal, and fuel will flow at the rate of pressure difference before and aft the injector and the amount of restriction present in the nozzle.
In slightly older cars, the fuel rail would be pressurized and regulated to a set pressure in the 40 - 60 PSI range. Since the pressure is constant, the volume of fuel that's dispensed while the injector is open can be calculated precisely.
I didn't see any sort of pressure regulation on the fuel delivery system on that engine; if that's the case, then it's difficult to determine (in advance) how long the injector should remain open to dispense the right amount of fuel. Also, as the fuel level changes, the amount of fuel being admitted during the injection cycle will vary, so the engine will swing from a rich to lean burn as the fuel level drops.
Oh, and never handle a fully pressurized injector. It'll shoot gasoline into you like the hypospray dispensers in Star Trek.
Nevin Williams yes, you are correct. there is a fuel pressure regulator. If you follow the tube from the fuel bottle it goes to a T. one side goes to the in-line pump. then goes to another T. one side of that T goes to injector. other side goes to pressure regulator which returns the fuel back to the first T. We need to get a pressure gauge on the line so we can monitor pressure.
I think only diesel engine injectors are dangerous because they run at thousands of psi. just like a pressure washer. This little thing uses like 40psi. it'd be like a little tickle.
Cool, I didn't see the extra plumbing...
Might need an accumulator to smooth out the pressure; lots of hydraulic hammering when valves are popping open and shut; it's such a small circuit, too.
Could there be any advantage with using a higher fuel pressure, or multiple shortened pulses from the fuel injector, per cycle?
hell yea! I see tunerstudio opened on that laptop! megasquirt ftw!
Can you turbo it or use the exhaust heat to run a steam turbine since you are running constant speed for long lengths of time?
Lol.. I'm sure your dad owns the water jet channel 😂😂
Since your shrinking the piston size and making the stroke longer does that mean if you modded it it could run diesel?
As a wise man in a Toyota Prius once said: Goats are like mushrooms, if you shoot a duck I’m scared of toasters.
very nice suggestion fuel injection and turbo also who needs fuel efficiency when you need power
American muscle
Are you using the Dyno to simulate a load to calculate accurate mileage under a real load?
what are the width of those tires? I noticed that the rear one was thicker than some of the racing tires available on the market. with a thinner tire, you could achieve less rolling resistance, as long as braking is not an issue lol
The Cummins, undoubtedly, came from the Jamestown, NY plant.
Did you ever consider running a gasoline engine at its optimum rpm, or even a bespoke gasoline engine optimized to run at a set rpm and run a generator which in turn would charge a battery pack to power an electric drivetrain, essentially running the engine in an efficient way and also benefiting from the advantages of electric drive?
I've managed to get my truck down to 4mpg pretty impressive right?
I got 2 mpg the other day. 2017 6.0L 2500 silverado 4x4
Matt Drew l got .5mpg going down hill while being towed.
what kind of gears and belts are those on the engine in the beginning of the video?
would putting in stronger valve springs help with valve float? id assume it would
valve float..yeah that mechanically can be addressed with stiffer valve springs. Will slightly increase rotating resistance of the engine though.
V.E. of naturally aspirated internal combustion engines can surpass 100%...maybe not with 1cyl though.
It's Hyde
just what I thought hahahah
@@MegaKencam Must suck to be a jackass, he's a lady killer, less like yourself.
Awesome
LOL When you said CAT, I said nope Cummins, then there was your sign hehehe.
I think they could deal (and regulate) ignition timing based on rpm and other parameters.
i would love to see more of this :)
Will do another next week!
Great :) am i correct in thinking they are using a megasquirt/microsquirt ecu for the fuel injection?
Gerrit-Jan Bergwerf that sounds familiar. I think you are correct!
Gerrit-Jan Bergwerf it is a Microsquirt
Look into into the Aprillia DiTech 50 direct air over fuel injection system.
How do you think they dealt with having to change the connecting rod?
Super. Do you have a specific role in the team? Do you prepare the skin with wax? Many, many questions on this very interesting project. So please make more video's!!!
I also attend Behrend, I am a simple sophomore, but i would like to join the club one day, haha
Have you guys thought about using solenoids to control the valves? I think Koenigsegg uses a similar system.
It allow you to open the valves quickly, keep them open, and the close them quickly, rather than more of a sinusoidal "open-closing" movement, where the valves are slowly opened and then slowly closed.
It's an ambitious thing to try, but it'd be pretty awesome!
ZPERO The club is open to anyone who want to come Friday nights.
Awesome project. Needs more two cycle.
In F-1 V8 engine, valves are actuated not by springs mostly because springs cant handle those RPM's, instead by liquid nitrogen , its most stable substance in temperature difference.
Makes you wonder what would happen if you built the engine as a hit and miss setup with the fuel controlled by an injector.
Then again you could skeletanize the crankshaft area of the engine then seal it back up with fiberglass or carbon depending on temperature needs as a way to shave the pounds off. Just enough metal to have the structure with a light weight material sealing to hold the oil in.
add fuel injection and time it( pulse spray) advanced before the intake valve opens, valve overlap sucks unburned fuel, but it helps cool the valves, the deal is to squirt fuel just before the intake opens, not a constant spray.
PS I really really really like the videos of the steam engine
Cumminside her
Seth Gordon Seth Gordon Can I join? Don't sleep with a guy if he's called Dirty Max.
that engine connected to a generator possibly by a Chas campbell pulley system, then to a electronic speed controller and from there to an electric motor.
Wonder if grinding that stock cam down some would improve efficiency even more.. longer duration perhaps?
Fuel economy =/= fuel efficiency.
Fuel economy is using as little fuel as possible, fuel efficiency is getting as much power out of a drop of fuel.
Have yall tried any experiments with oils? Maybe some e85? It doesn't have the same thermal mass as gasoline, but it's knock resistance is amazing.
so 6hp down to 2.5hp? is that due to long stroke and small cylinder?. 18:1 compression is insane. most cars run wayyy less. is the compression the key to efficiency? im only asking bc i would love to get better mileage and as im soon to rebuild my trucks motor i would love advice on how to set it up. ive heard some big racing motors actually have great efficiency but bc they are run so hard they never get great mileage.
Cummins m11 is used in marine and semi trucks. Most truck have 13 or 15 liter engines but some do have 11.
Mini turbo advantages smaller cubic inches but not compatible with high compression however go to propane 110. Octane.
Or small diesel boost through the roof no detonation .
Ryan Phillippe and Danny Masterson fuse together to visit strange peoples starting their engine only once per race to claim irrealistic MPG numbers with 25% thermo efficiency of course....
Carbon fiber pushrods but massive non machined enormous rocker arms...
I'm sure the stock camshaft is not hollow.
They could drill holes in 50 % of the parts to save weight.
Use ceramic coating ,and maybe an other thing than a pushrod engine to increase mechanical efficiency first...
Interesting anyway,i wish i could do those kind of stuff.
I wonder what these guys think about the Honda GC160 design. It has a plastic overhead cam and an in-oil timing belt.
The Cummins cutaway engine is probably on loan from Cummins Jamestown Engine Plant about a 1 hour drive east of behrend.
So it's a Briggs LO206 that's been de-bored to less than half it's original displacement, crazy compression ratio, crazy rod ratio, running 4400rpm using a cam ground for a 7100rpm 206cc? How can it run lean enough to get that MPG while doing any work on planet Earth?
Which is why making a new camshaft that hit's peak efficiency in the middle of the ~2,000-4,500 rpm rev range is a good idea.
Is that Megasquirt efi? Datalogging will get your tables right. It just takes time, and for the engine to be run at as many throttle positions for every rpm in the rev range. 4100 rpms seems pretty fast for a briggs engine. Usually valves float at 3600. Maybe you could try something lighter. Surely someone could make some titanium valves, retainers, and locks for a gx35 motor.. maybe some beehive springs or at least some slightly stiffer valvesprings to control the valvetrain a little better. I'm assuming the valves and seats have been treated to a multi angle valve job. If not, more power and efficiency can be had there. You could turn the bottom of the valvestems in a lathe to allow more airflow. Maybe lighten the shaft rockers by drilling some holes to remove material.
Keep after the engine tuning. Efi has the potential for better power at wot and better part throttle driveability once you get it tuned right. As long as you use a larger throttle body than a carb, you have the potential for better power everywhere in the rev range.. meaning you could make the bore smaller yet and still make the same power. Very interesting stuff.
Subbed.
Hey, Im a mechanical engineer at cal poly pomona and we are starting a super milage team here this year. I wanted to know if you had a 3d model of the b&s 206 that you could share with us?
I think the main issue would be the loss in power in the transmission cause if u have no resistance there its just aerodynamics which is fairly simple
when youre not worried about getting laid, geniuses are born
Some car manufacturers add a second valve spring to prevent valve float for higher rpm motors
If they did that with this engine, then they'd lose a bit more power, and they'd have a decrease in efficiency due to the additional force required to open the valves.
I've improved my old 840 hspwr Chevy 400 and for really great gas mileage
You're tuning your engines while i'm riding my chainsaw bike that absolutely chugs gasoline :)
I've calculated mine to be about 19.6 MPG :D
Poptart McJelly hahaha that's terrible efficiency for a bike! Sounds like you're running it really rich
the engine diesiling will stop if you modify valves to have dual springs and a different lobe on can that will stop engine flutter at higher revs also use bearing on crankshaft
