Abstract: During operation with part load, a gasoline internal combustion engine is operated with a lean air/fuel mixture by auto-ignition. During operation with full load, spark-ignition is used to operate the engine. The internal combustion engine is operated in three auto-ignition combustion modes depending upon magnitude of a predetermined operating parameter.

In the gasoline reform auto-ignition combustion mode that may be selected during operation with low part load, a first fuel injection during an exhaust gas retaining phase produces sufficient amount of active fuel radicals for promotion of auto-ignition of air/fuel mixture produced by a second fuel injection during the subsequent compression phase.

Abstract: A knock control apparatus has a knock sensor and a signal processor. The signal processor integrates a knock sensor signal and differentiates the integrated signal. The signal processor detects a period in which the differentiated signal exceeds a threshold, and detects a peak of the differentiated signal.

Alternatively, the signal processor detects a peak generation time and calculates a ratio between the detected signal generation period and the detected peak generation time. In this instance, the signal processor determines the knock when the calculated ratio is within a predetermined range and the detected peak generation time is less than a predetermined time reference.
