2 stroke diesels are not a new idea. almost all of the engines Detroit Diesel made for over the road trucks and other such applications were 2 stroke. best part is they leak and are just as dirty to work on as a gas 2 stroke
2 stroke diesels have an exaust valve in them. That is why they are turbo charged because they have to force the intake charge into them. That is a crude explanation but google would be better for something more in depth. So, no, your RC car is nothing like a two stroke diesel engine. Unless it have a valve and a turbo or super charger
