That was not the question

Every engine which burns something is combustion one by principle. I asked because I do not know about any serial petrol/diesel/bio-fuel engine which is not based on combustion principle.

Anyway I am strongly against bio fuels as they are known now. They made much more harm than good and the only thing they have been good for is to tunnel billions on subsidies.
