A method and means for improving the efficiency of movable-piston internal combustion engines and reducing the pollution of the environment produced by their operation. The exhaust gases from the engine are compressed and afterburnt, and this resulting heat energy is converted to mechanical energy in a gas turbine connected to the engine shaft. Details of preferred combustion chambers and of a preferred unit combining compressors and turbines are also given. In one embodiment of the invention, a piston engine is arranged for stratified charging and the power stroke is adjusted to deliver exhaust gases at high pressure. In order to increase the efficiency of the gas turbine, portions of the turbine can be coated with a catalytic material.
