ABSTRACT:
An inner/outer cooling system for the cylinder of a piston combustion engine is provided by inner oil cooling and only the top part of the cylinder which is not reached by the inner cooling is cooled also by oil from the outside. The single steps are given by a special piston construction in a special very heat-sealed combustion system and through a special distribution of the cool oil spray in the combustion cylinder working.
