Device for changing four-stroke internal-combustion engine into two-stroke internal-combustion engine, has inlet valve provided with inlet opening in combustion chamber, and outlet opening provided in region of bottom dead center of piston
The device has an inlet valve (4) provided with an inlet opening (3) in a combustion chamber (1). An outlet opening (2) is provided in a region of bottom dead center of a piston (12). Air flowing through the inlet valve is raised under constant pressure through a combination of two air-blowers (6) in lower and higher speed regions by a mechanical loader and an exhaust turbocharger, respectively. Fuel e.g. diesel, is supplied at high pressure by a direct injection nozzle (8) in a cylinder head (9).
