Diesel Model Engine 1ccm Four Stroke

[nitroairplane]

I know you make and sell the WOHM radials any chance of selling some of these?

[SakoTGrimes]

I need 250 of these working together to power my 92 Ford Fiesta!

[lomtafix]

is that engine self build?

[10blood]

isn't the prop a little off balance?

[bratte68]

@10blood that's right, it was a mistake to press the reduce-bushing too hard. The prop was warped and ran out of trace. Now the prop runs perfect

[10blood]

@bratte68 Perfect prop! Woot!  lol

[ducatiss900]

I use John Deere starting fluid; this info came from Davis Diesel Developments in the US- caution it is necessary to puncture the can

[hopeso]

@ducatiss900 I don't puncture the can. I put on a spray nozzle from a WD40 can with the tube. I punch a hole in the lid of a jar and spray the can out into the jar through the hole. This blows off all the propellant that can contaminate the fuel mix. Also, I'm not comfortable punching a hole into a pressurized can that contains an extremely volatile fluid. One spark,,,,,

[GSRGOPEDRIDER247]

awsome!

[rangersmustang]

Too bad its not a real diesel

[wanagthigh]

Right on! You found another way to pollute the air....

[024reredrum]

I wonder if tvo would work better in these?

[SthealthRaider]

how can i convert a petrol 4 stroke to diesel? model engine

[robinhooodvsyou]

These engines have higher compression ratio than injecteddiesels and the fuel contains a big amount of ether and in most cases the compression ratio is adjustable just by turning the contra-piston`s screw at the cylinderhead.

It looks like this engine doesn`t have it, two stroke engines have.

The rotative mass keeps it running (the propeller), and it wouldn`t work without it.

[wheelXJnintythree]

diesels use injection pumps for timing. a carbureted diesel might blow up.

[kona181]

Well 2-strokes can put out more power but they only do at high rpm's where as 4-stroke have more consistent power at all rpm's.

So it depends on what you intend to power with your engine as to use 2-stroke or 4-stroke.

[datzfast]

@kona181 the power is rpm and prop size so if they swing the same prop at the same rpm power is equal

[diymania]

A four stroke makes alot more power than a 2-stroke for the same size as the two stroke blows half the fuel outta the exhaust. A four stroke engine is ALWAYS more efficient than a 2-stroke!!

[robinhooodvsyou]

And two stroke engine has also more pumping losses, the compression starts at the top of the exhaust port.

[theleakytaps]

like ass a 4 stroke of the same size is more powerfull. its more efficent, not powerful

[highdeserthater]

it really depends on everything. injection timing/valve timing/ porting, mixtures, temperatures, compression ratio, stroke, everything. with an echo chamber, a two stroke wont blow all of the fuel out. if you time all engines no matter how many strokes, they will run about the same. ive seen two strokes run much more efficiently than fours. most times the other way around. most four strokes are designed to run at constant RPM. most two strokes are made to bounce about.

[SpiritsoftheWolf]

now that is the QUIETEST 4 stroke engine, nice video

[anthacdc]

im having trouble finding ether in Australia is there any other chemical i can use to replace it?

[bratte68]

unfortunately there is absolutely no chemical to substitute ether. No other fluid has its volatileness (boiling point 35°C) and the absolute low ignition point of 180°C.

[hopeso]

@bratte68 yes, there is no substitute for ether. But a model diesel engine CAN run on a fuel with no ether. The problem is getting it started. You can use a high ether prime to get the engine warm enough to start with a number of prime runs, or you can just use a heat gun to get the engine hot enough for a start. But the engine may run rough or a compression ratio that's too high. See my videos.

[psychotikpaisano]

@anthacdc

Thank the meth heads for that

[xGSxMayhem94]

umm...

4-stroke diesel???

[wheelXJnintythree]

its not real a diesel. it needs a fuel injection pump

[DeereBoy95]

no it dosent

[douro20]

Some of these will run without ether but not without very high starting compression.

[30GB]

wow its diesel injected type other rc engine use plate thingy to run

[SKarmytech]

Thank you for your message. The information was very welcome. Have a good day.

[SKarmytech]

How much did thsi engine cost?

[eckertc2]

Can an engine like this run off of filtered used vegetable oil? I would like to use one to generate free electricity and use the heat from the engine to help warm up the fuel tank that holds the used vegetable oil to keep its viscosity at a manageable level.

[bratte68]

There is no chance to run such an engine with this oil only(pure).You can substitute only a part of the kerosene/castor in the mix because there is no high pressure injection used in "large" diesel engines where the diesel fuel is atomized by injection nozzles. This engine is also not designed to run long times and needs air cooling (prop).The engine also would not ignite without containing ether in the fuel and there is no chance to obtain such high compression ratios to burn standard fuels.

[bighunterman77]

@bratte68 no injection pump or injectors? how exactly does this thing run?

[simmo595]

wait a minute on discovery science u start the motor with diesel then switch it off and switch on oil like valves ask for more info if u need.

[detroit83stang]

How does this work? is there a fuel injector?

[bratte68]

Hi, I try to explain in my bad english: It works with a special fuel, containing ethyl ether, kerosene and castor oil. ether is the ignitor, kerosene the main combustible part and castor the lubricant. These little engines called "diesels" work with adjustable compression. The mix air/ fuel is compressed so high that it will ignite. They are so called "self ignitors" the lever between propeller and cylinder is for comprssion adjustment, this works via excentric camshaft base. Greetings
