Abstract
A combustion control system for a diesel engine provided with a fuel injection system and a sensor for detecting an ignition timing. The combustion control system comprises a control unit which is configured to control the ignition timing to be restored to a target value when the ignition timing shifts from the target value owing to circumferential factors such as cetane number of fuel. Preferably, the ignition timing is controlled to generally coincide with or be retarded relative to a fuel injection termination timing. This regulates an ignition delay period to be longer than a fuel injection period in a predetermined engine operating region, thereby effectively accomplishing so-called low temperature premix combustion.
