well diesel is lubey (is that a word?) as it is, and you could run propane injection on one Im sure. I was thinking it would be cool to have a propane sled...without even thinking that a 2 stroke engine runs mixed oil lol. Put some diesel injection on a propane engine! hah (that was a joke)
Two stroke diesels have a supercharger and oil in the crankcase, like a four stroke, a different animal altogether than a small two stroke gasoline engine.
There are small two stroke diesel engines similar to 2 stroke gas engines. Popular in the model airplane category. Thing is, if someone has one, don't just pick up the plane and flip the prop. If there's any oil (Diesel) left in the engine at all, it WILL start. This has happend to several people and if they are lucky, they are able to retain grip on the plane when it starts unexpectedly. Then they just have to hold on till it dies again.
I'm certain you could. Probably the place to start would be to try to adapt the fuel system from a propane generator. Oil injection may need some work, as the oil may not mix with propane the same way it does with gasoline.
You would probably get lower performance unless you could raise the compression and experiment with the port timing.
depends on whether the crankcase is open or not. large motors with superchargers are closed with the compressor pushing the mixture thru. it doesn't matter what the fuel is. if the crankcase is open, you need to bring lubrication and that would be tough with propane or CNG.
Although you have no direct way to mix fuel and oil in a propane system most modern outboard motors have a separate oil and fuel delivery system. It is usually a mechanical pump although vacuum pump or a venture injection could be used. Choosing the correct oil would be a challenge but with the poor storage quality of “modern” gasoline it would appear something worth pursuing.
