It's a spark ignition petrol engine.

@@nathanamosengineering1836 not diesel right

Unfortunately yes they do get dirty like any coal fired boiler but it's easy to remove the boiler for cleaning when needed.

No I have only built one and it is not for sale. Glad you like it though.:)

I made it all from scratch.

Thankyou.

Thanks Colin, its getting there slowly.

Thanks Colin.

Thanks, It takes a lot of modifications to get a model engine to run nice and slow. Many engines are designed without sufficient understanding how carburettors and gas flow scale, with many choosing sizes that are way too big to produce a fast moving well mixed charge reaching the cylinder. Air and liquid fuel just cant be scaled down, so keeping gas flow up is crucial. Also the geometry of bore and stroke work against slow running. Excessive compression and flywheels that can not store enough inertia compound the problems too. Every engine I build I make changes from the start as its obvious that it would run poor with some of the suggested dimensions.

Thanks.

Yeah, but it took ages to get it to produce any decent usable power and still be flexible to run slow when required . Making the volt meeter was a challenge too. all worth it though.

Thanks Colin, I will slowly be uploading videos of my collection. Its a bout time I share a bit:-)

Glad you like it. Applying acoustic engineering principles helped me quieten it down lots whilst easy starting is achieved by having an excellent magneto and fuel mixture set up. So many people put up with poor running and starting engines with week magnetos and knackered engines. The home made radiator was not quite big enough do dissipate all the heat sadly whilst mounted in the shed. Cats, dogs, children and engines should never be mixed as it can make a bloody mess :-D.

Low RPM, Thick cast iron block, water jacket and external exhaust.

At the bottom of the pipe is a tee with a drain hole to drain out any water or condensate. At the back of the shed was a silencer with a capacity of 25 liters also with a drain hole. I'm far from a short sighted, stupid or an idiot. I design and engineer things carefully and think of all possible issues before starting. The exhaust on this is almost totally condensing due to the large capacity hence ample drainage. It was done to avoid having to have a flap as they make noise of their own don't they. Thanks for your assumption and concerns though lol. I say this in the nicest possible way..... Best not make assumptions. Much better to ask how water, rain or condensate is prevented from collecting or building up rather than assuming. Kind regards etc.

No.
