Small engine running on propane

[TheCerberusInferno]

what's that shit

[shovelheezy]

Good job! I used to dick around with lawnmower engines all the time, you can really learn alot from it. Keep it up! Even if your parents get annoyed ;)

[losttreasurehunt]

Great job

[noekiyu]

sound kinda like a fork lift

[FireDropTechnologies]

Calcium-Carbide+ water=Acetylene

try running it on that, with a bit of HHO gas once it starts and the fuel cell comes online and starts producing. then you can lean out the Acetylene gas to just a tad bit of hydrocarbon fuel. A Renewable Hydrocarbon fuel! all it takes is a propane carburator, or a set rpm engine.

OMG!!! NIN is the best band ever!

Nice video, Dude don't let your hair catch fire.

you know you need the blade to act as a flywheel

[WreckRman2]

Do you even know what a flywheel is or does? The blade helps counter balance the momentum of the engine.

[chrisross2343]

no shit thats why he said you need it

[jefro0]

No, you do not need the blade to act as a flywheel. It may on some installations but only for a mower.

Propane has slighter more energy if it is burned at the much compression. Under a normal gas compression it is up to 30% less efficiency. Propane some 108 or so octane. That means a 14:1 compression. Not the normal 8:1 in gas motors.

@jefro0

you are wrong the built in flywheel is too light and makes the engine jerk and need momentum to swing around for the next compression and fire

[jefro0]

I disagree. I have played with small motors for 40 years. The blade is only one of many attachments that could be installed on a vertical motor. The same motor is used for pumps, compressors and generators. All have different mass and may be disengagted.

@jefro0

lawnmowers have a lighter aluminum flywheel to use with steel blade for cutting and some others may have installed cast iron flywheel to use with accessories like pumps and clutches etc instead of blade which has more mass

[simusfr]

@30GB You don't need the blade, but it could help. The flywheel is heavy enough compared to the output power of this engine.

[30GB]

you are wrong the flywheel is aluminum its only used to cool and hold the magnet for ignition

[simusfr]

That is is made of aluminium doesn't mean that its inertia isn't sufficient. Low power engines like these have only small torque and compression, so there's no need to have an important weight attached to the shaft. Lots of these engines, including mine, idle perfectly without additional mass.

[30GB]

I know from experience, fixed over 100 briggs and lawnmower engines. The flywheel is used to have momentum after the combustion the piston send power to crankshaft then to the flywheel so the next rotation it can compress the fuel mixture and fire using the momentum from the cast flywheel.

Lawnmower engines that dont have a cast flywheel it uses a blade as a flywheel and they are design that way without it, the engine will have rogue idle and sheer the key way for the flywheel.

[pumpman0]

I think you just wanted to get high on the fumes Lol

[mark22300]

LET IT BLOW UP!!

[GozillaFirefox]

boring

[pepperrain573haterz]

sounds like its gunna shit the bed

[VwEuroBoy]

one get a hair cut second dont bite your tounge off and third that engine is history if you keep that up

[howmuchart]

any barber shops in your area?

[kc9hyr2]

i like how at 00:04 you look to see if anyone is around.>>

[redtibby01]

makeing sure mommy and daddy wasn't driving up

[D409er]

... well, at least you didn't kill yourself. Well done, mate! Get a hair cut.

[yuandrew]

The small portable grill regulator valve is definitely not supplying enough gas to properly run the engine. You'll need to supply around 36,000 BTU/hrs of propane at normal running speeds for most lawnmower engines as I've found with my propane lawn mower project.

I used a simple propane torch head that had no regulator, only a needle valve and I also drilled out the orifice in the nozzle with a 1/16 bit to allow more gas to flow.

[onlyinternet]

is that a FART Machine!:))) lol!!

[HalfCockedMD]

No, a fart machine would run on methane, not propane.

[NoobiiPower]

Thads not the smallest propane engine....

[krankiev]

never said smallest...

[horacionav]

In Argentina we´ve got cars running on propane for more than 12 years, and it works perfect

[Winters517]

but it is also like 30% less efficient

[krankiev]

bull crap mine make more power and cost less to run than with gasoline

[nahviiiii]

awesome! but isnt it kinda hard to keep running?

[marshallspikebanana]

BOOOOOOM!!!!

[G4S23]

nice work how many CC is that engine

[05cr125rider]

its running on its own oil lol just kidding man good job

[volvo09]

Good work. When I was that age I loved messing around with small engines.

[silverchris2]

I switched to a real carberator on a known running motor and it ran and idled but could not raise the rpms cause it was leaning out. Real propane regulators I find are atleast or over 60 dollars. At the end of that tube that feeds the propane has a little cap at the end with a very small hole in it. I think that small hole needs to be enlarged for it to rev up.

[misturchips]

@silverchris2 If you're using a propane torch head (Like I was), you'll need to bump up the size of the orifice (little cap w/ small hole) to allow more fuel to flow. Your other option is to tilt the bottle so some liquic comes out - be wary, though. The orifice is sized to get a nice blue flame with the air provided via the holes in the side of the torch head. If it's too lean, you can cover one of the holes with your finger 'til the RPM raises based on the tank valve setting. Good luck!

[rotax340]

try with a very small propane tube, you will have a good idle and better trhottle response, and change your regulator, get a good one
