ABSTRACT:
A single-piston or multi-piston two-stroke internal combustion engine for introducing into the working space or working spaces of the one cylinder or of the several cylinders respectively a pressurized fluid such as a gas, ambient air or a gaseous mixture or a mixture of a gaseous medium and a liquid at approximately an intermediate height of the cylinder working space between top and bottom dead center positions of the piston head surface for separating inflowing fuel-air mixture from the exiting combustion gases and for establishing a layer charge overlying the piston head. The two-stroke engine is provided with an additional inlet port for admitting this additional pressurized fluid into the cylinder working space, the inlet port being in communication with fluid supply means and optionally including an automatically pressure operated or positively actuated control member.
