2-stroke IC engines with valve timing for motor vehicles with working stroke executing intake, compression, and working strokes

摘要

Fresh gas pre-heating into the valve chamber (3) of the fresh gas valve (4) creates a constantly high heated air pressure. Shortly before the upper dead center is reached, the fresh gas valve is opened, and the open exhaust valve is closed simultaneously, and the injection valve (7) injects fuel into the gas flow. The petrol-air mixture is under high pressure, and passes through the valve slot (8) into the cylinder chamber (9). The working stroke can commence after the fresh gas valve is closed.
