Abstract
A system for controlling combustion knock, if occurring, in an engine by suppressing it by retarding ignition timing. The engine is equipped with traction control for preventing the driven wheel of the vehicle on which the engine is mounted from slipping. In the system, if the traction control is in process, by leaning out a mixture to be supplied to the engine at a high engine speed region, the knock control is discontinued so as to prevent the exhaust gas temperature from rising excessively and so as not to degrade a catalyst installed in the exhaust system and exhaust emission. The knock control is suspended for a period even after the supply of the lean mixture has ceased.
