Does anyone have any good links or care to explain how a two-stroke diesel works? I can't find anything and when I think about how a diesel works and then how a two-stroke works I just can't put the two together.  :(

It would work like a two-stroke gasoline engine. The heavy fuel oil is a lubricant in itself. It just uses higher compression to detonate the fuel-air mix instead of a spark plug. In the Wärtsilä-Sulzer I believe the cylinders work in pairs; one cylinder compressing the fuel-air mix of the other cylinder. Basically having cross-feed transfer ports.

Being a diesel it wouldn't have any spark plugs.

I do like the turbo charger that's larger than my house.

Ehhhh it was a joke......................... ...... <G>

Thanks diehard. I was kinda leaning that way because I knew the fuel/air mixture had to go through the crankcase for lubrication. I just didn't really know that you could build a diesel without the fuel injection. Obviously crankcase pressures aren't high enough to cause detonation.

Many, Many years ago I tagged along with a friend to our local drag strip, (car drag strip that is).  He was into drag racing, but I had little interest except for the beer that they sold.  We were in the pit area and he was talking to a couple of the owners and the question of engine size was being discussed.  I remember one of the owners making this comment, and I have no idea why I remembered it for so many years.  "The only substitute for cubic inches is cubic money".

As for two-stroke diesels...
Detroit diesel made 2 strokes for years for road use... the 6V92.

 A lot of city buses used them..a very disdinctive exhaust note.

Technically speaking,most RC plane engines are 2 stroke diesels,tho they dont burn diesel fuel!

 IIRC the germans use a 2 stroke diesel engine in 1 of their A/C,I think it was designed to burn a coal based fuel.

It was the Ju-86 high altitude recon plane. Most if not all German aviation fuel was coal-based Fischer-Tropsch synthetic fuel.
