3hp Briggs & Stratton running on compressed air.

[thebigmann25]

how do you have oil going to the piston or is it a 4 stroke?

[eddievalleytrailer]

@thebigmann25 It is a 4 stroke. Still has regular oil in the crankcase. 

[Rythymoxide2020]

I think this a rather intellegent idea. 1. you are reusing a engine that could possibly no longer run on gas and so there is a conversion to steam. You have just saved another hunk of cast iron from being barried. 2. Steam is about the coolest idea and is power that started world we have today.

[clackdwack]

at the end of the day the problem is that air compressor in the back ground, theres always a third power

[eddievalleytrailer]

@clackdwack Look at my response to scoobydog411. I plan to build a boiler for it and set it on my woodstove. It will be running on steam, no air compressor required. It will both humidify the house as well as circulate warm air when a fan blade is attached. What were you thinking?? It was magic or something?? What is a third power? What are powers 1 and 2?

[Tinkrr1]

Why aren't any of you guys trying to recapture the compressed air thats coming out of the engine, to help replenish the air thats being used? If you don't know how l'll help you. You'll have to have a 4-cycle engine thats stock, a reed switch, a three-way solenoid valve & 1-way check valve for starters.

@Tinkrr1 can i get some plans? doc_comet@yahoo.com

[fairyheli2]

sounds smooth and like a steam engine

Hi

Is it necessary to drain out the air after every use or once a month or once a week is good enough. I have a Craftsman 33 gallon air compressor but I not sure if it will rust if i drain it like 4 times a month and not after every use. I use it only 2 times a month.

thanks

[eddievalleytrailer]

Self, I do see a couple of potential causes for your trouble. 1st of all, I think your flywheel is too light. It has to be heavy enough to keep the engine turning while it is in the return stroke. Also, I think the timing is off a little. The intake valve must open just after the piston starts the down stroke and close before the piston reaches the bottom. The exhaust valve must open as the intake closes and close as the intake opens.

Hi Eddie,

I like the video....

Could you tell me how much air is being used when running the engine at high speed?

For me at least, it wouldn't be of much use unless it could run for an extended period of time using a portable air tank. After all, these small engines are used in portable applications...

Thank You.

[eddievalleytrailer]

@SparkDr1 It is not really designed to run on compressed air. The compressor was for demonstration only. It was designed to set on my woodstove attached to a boiler filled with water to both humidify my house and to circulate warm air.

Hello Eddi

I just got a two stroke edgemower engine and i tried to run it on compressed air at 40PSI. The valves are still in place, the covers are off, and they loose pressure; if i try to cover the valve openings, the fly wheel will not spin? How do i fix this problem ? What should i do about the valves in order to run the engine on air? Thank you so much in advance for your help.

[eddievalleytrailer]

@SelfReliance4ALL Valves in a 2-stroke? The only valves in a 2-stroke are the reed valves which will not allow the engine to run on steam (or air pressure). The only way I've seen a 2-stroke run on air is to put the air into the sparkplug hole and use a valve connected to the engine to turn the air on and off. It is much easier to make one out of a 4 stroke engine. You could post a video of your engine so we could see what is going on with it.

[SelfReliance4ALL]

@eddievalleytrailer Hi Eddi. I just finished posting the latest video on my engine. You can view it on My Videos channel( it is the first one from the top). I don't know another way to share it but this; it will be awhile until it becomes public. Anyway, it is there and i look forward your advice. Thank you very much.

[ivankoran]

you are the only person i've seen do this who is smart enough to not put thier fingers in the flywheel when starting it [oops, there goes my hand ^__^ ]

[eddievalleytrailer]

@ivankoran Yeah, it could take your hand right off.

[92rs25th]

put a 5hp flywheel on it and it will run even smoother and have much more torque at mid to high RPM. ive done this myself :D

[nibbler125]

youre engine runs nice and smooth. did you put extra heavy valve springs on?

[eddievalleytrailer]

@nibbler125 Thanks, It still has the original valve springs.

[scoobydog411]

do you plan to run it on steam ?

[eddievalleytrailer]

@scoobydog411 I plan to build a boiler for it to sit on top of my woodstove, attach a fan blade to it to humidify the house and blow the air around.

[Hallaran]

Cool!

[mowersman]

Hi

Any idea on how may Hp i would get out of one of these compared to the standard 3Hp

Thanks

Andrew

[eddievalleytrailer]

@mowersman , I would guess about 1/2 of the original power. It would, of course, depend on how much steam (air) pressure you are using. I haven't tried to run anything with it, but it does seem to be fairly strong. Thanks for watching.

[crazyfvck]

Man.. That thing can really go down to some low rpms.. Throw a decent flywheel on there and it could probably drop down even further. PUT-PUT-PUT-PUT : )

[guitarsncarz]

For a boiler, why not get a 2gallon air compresser tank? It's already made for pressure, and even have draining valves(For condensation in a regular compressor) to get rid of the left over water, but you probebley need to drill bigger holes where the steam would exit the tank like 1/2 vs the original 1/4 or so. That size boiler I think would power a 3-4hp, maybe a 5hp

[beke6874]

Heat does a number on things that we would normally consider pretty strong. An air compressor tank might take the pressure but not when heated. Propane tanks on the other hand are made to withstand fire damage. So...

[djbAnks]

hey eddie I am looking into building a converted steam engine and plan on doing the same as you. throw this in google: "lynxsteamengine" He has plans for a boiler and how to convert a briggs useing the valves. :) i might buy plans from him in the next few.

How did you convert yours? I really am interested. /thanks

[eddievalleytrailer]

I welded 2 more lobes on the cam. That's about all. The air goes in where the carb was. Thanks for the tip on the boiler.

[eddievalleytrailer]

@djbAnks, I did use the valves in the engine. I simply modified the cam to make the valves open every rotation insted of every other.

[19531998]

I am making one of these with a 5 hp briggs and I am going to put it on a old industrial belt sander that needs a motor.

[eddievalleytrailer]

GREAT!!! Let me know how it turns out. I'd like to build a boiler for mine. Run it on steam and have it run a generator.

[amandabstewart]

wow the dude in this video is HOT
