Method for variable throttle with which control device has variable valve impulses for four-stroke piston engine, involves absorbing load by variable back thrust control with ambient pressure and with positive pressure

摘要

The method involves absorbing a load by the variable back thrust control with the ambient pressure and with a positive pressure, into an actuator without changing the intake cross section unthrottled up to the lower dead center. The load absorbing excessively is closed by an inlet valve, opened around a gap, is throttled in a suction device and pushed back till the inlet valve.
