ABSTRACT:
A feed back control system and method for direct injected engines, particularly useful in marine applications to avoid knocking. Different types of injection control are applied to achieve this depending on the engine running condition when knocking occurs. Both injection initiation and duration are controlled. Injection timing is employed primarily to control knocking under steady state running. Both injection initiation and duration are controlled to avoid knocking under acceleration.
