As I have indicated before, I'm very diesel ignorant. I just know the basics, very basics.
In a two-stroke diesel engine using forced induction seems necessary but at the same time I see challenges. In motorcycles, which I have more knowledge in, the crank seals are an important component for the two-stroke engine process to function properly. If there is an air leak at the crank it it's the same thing, if not worse, as having an air leak between the carb and the head. The seals being nice and tight are essential.
I know there are examples out there of forced induction two-stroke motorcycles but the modifications are extensive as the crank seals aren't designed for that high of a crankcase pressure.
So, my question.
Do two-stroke diesel engines commonly use forced induction systems like turbo chargers or superchargers?
I would imagine that some kind of exhaust valving is essential as well in order to use back pressure as a regulator of exhaust gasses. I'm thinking out loud here and not making a claim. My other question.
If so, what are some of the design considerations?
AND my last question?
Would a mechanism for exhaust gas regulation include some kind a poppet valve as in a four-stroke engine?
I would imagine that if above is the case then this would still be a two stroke but some type of hybrid design, using poppet valves. Again, thoughts, not claims.
