KNOCK CONTROL IN INTERNAL COMBUSTION ENGINES

摘要

A method of controlling the operation of an internal combustion engine (1) provided with a memory (3, 4) storing values of a particular operating parameter ( alpha z) for use at various operating conditions (n, Ps) comprises operating the engine using those stored values, detecting knocking using a knock detector (11) and adjusting the operating parameter in response to signals from the knock detector (11), calculating the length of time ts for which each set of operating conditions is maintained and altering the stored parameter values by an amount which depends on the calculated length of time (ts).
