Abstract
An ECU executes a program including the steps of: calculating a base timing of injection (INJB); determining whether an engine knocks; if the engine knocks, increasing a correction value INJK(I) applied to correct a timing of injection; and calculating the base timing of injection INJB plus the correction value INJK(I) to obtain a timing of injection INJ.
Claims50
A control device for an internal combustion engine including injection means injecting fuel directly into a cylinder, comprising:
- detection means for detecting that an engine knocks;
- and
- control means for controlling said injection means to provide a faster timing of propagation of flame in said cylinder toward an intake side when that the engine knocks is detected.
A control device for an internal combustion engine including injection means injecting fuel directly into a cylinder, comprising:
- detection means for detecting a timing of propagation of flame in said cylinder;
- and
- control means for controlling said injection means to advance a timing of propagation of flame in said cylinder toward an intake side when said timing of propagation of flame in said cylinder toward said intake side is slower than that of propagation of flame in said cylinder toward an exhaust side.
A control device for an internal combustion engine including an injector injecting fuel directly into a cylinder, comprising:
- a detector detecting that an engine knocks;
- and
- a controller controlling said injector to provide a faster timing of propagation of flame in said cylinder toward an intake side when that the engine knocks is detected.
