A diesel isn't a 2 stroke

A diesel generally has the combustion chamber in the piston, I've wondered how this would work I a saw. Probably not well

Why not? Theory?

I hear you so does the one ring piston faster in the cut than the 2 ring stock form 372 xp?

ant time I need to replace a piston in a 372 it gets the 1 ring piston

I don't think the plug location is great for that and I think the piston would be heavy and problematic. I'm probably wrong,I was once before. Lol

371 piston everytime.

Your thoughts on this scott.

I don't know *s-word about diesel engines. I think the 345 has a dished piston.

I dished a 440 once, don't think i'll do another

True, forgot about that. We used to have one in an old 20 ton P&H crane

They are called a 2 stroke but I'm still thinking about how. Lol

DT 466 if I remember right

DT466 is direct injection turbo engine. The old 2v91 and stuff like that Detroit's are.

 

[jmssaws]

Yes Detroit is what I'm referring to

Maybe that was in our B&E then, I know our P&H was a 2 stroke

 

[jmssaws]

Lots of power units and stationary equipment have Detroit motors

They fire every stroke.

I understand that but I'm still wrapping my head around how the valves work
