ABSTRACT:
In a four-cycle spark-ignition internal combustion engine, knocking under a high compression ratio can be prevented by replacing the burnt gas which remains within the cylinder at the end of an exhaust stroke by a gas, such as exhaust gas, which is at a temperature approximating normal temperature, and that the ignition timing is controlled so as not to precede the knocking limit ignition point.
