Abstract
A method for controlling an engine includes selecting a control point consisting of a combination of an injection timing of injecting fuel and an ignition timing of igniting an air-fuel mixture, corresponding to a selection on a parameter map Mhaving the injection timing as a first axis and the ignition timing as a second axis, defines a parameter region Rsurrounded by a first limit line Liindicating an advance limit at which preignition is restrained, a second limit line Liindicating an advance limit at which smoke is restrained, a third limit line Liindicating an advance limit at which knocking is restrained, and a fourth limit line Liindicating a retard limit at which combustion stability is ensured on the parameter map M, and further includes a step of selecting the control point so the ignition timing is brought to maximum advance within the parameter region R.
