ABSTRACT:
An Otto-cycle engine in which the expansion ratio is set in the range 11:1 to 16:1. A combustion knock sensor detects the onset knocking and a valve actuating timing-adjusting device mounted on the cam shaft that drives the suction valve, delays the timing at which the suction valve is closed, via an actuator in response to the output signal from the sensor. Thus, the substantial compression ratio is adjusted.
