    摘要： An internal combustion engine includes a single sluice (3) which opens asymmetrically and one-sidedly in an exhaust channel (5) and which runs tangentially within the cylinder (1), diagonally to the cylinder head. A rotating flow is thus obtained in the cylinder along its inner wall, thus ensuring a complete and reliable ignition, a low fuel consumption and a low pollutant content in the exhaust gases.

    摘要： A two stroke engine having an exhaust port formed in the cylinder wall. At the upper portion of the exhaust port, there is provided a rotary type exhaust timing control valve which is adapted to be actuated by an electric servomotor to control the exhaust timing in accordance with the engine speed. A control circuit is provided for controlling a power supply to the servomotor in accordance with the engine speed and the position of the valve. A timer switch is provided for providing a power supply to the control circuit for a certain time after the engine ignition switch is turned off so that the valve is moved to the retracted position after the engine is stopped. As the valve is thus moved to the retracted position, carbon deposits on the valve is scraped off by a scraping edge formed in the cylinder.

    摘要： A multicylinder two-stroke internal combustion engine has a plurality of reciprocating pistons arranged in a circle about a central cavity in which is located a rotary distributor driven in timed sequence with operation of the pistons. The rotary distributor includes internal cavities which may connect through ports in its outer cylindrical surface with the working cylinders to control the flow of intake air, scavenging air and/or fuel to the working cylinders. Scavenging air can be precompressed either in a preceding cylinder, taken in ignition order, or in the crank chambers beneath the pistons.
