PROBLEM TO BE SOLVED: To prevent deterioration of combustibility at low operating temperatures in an internal combustion engine performing low temperature combustion. SOLUTION: Implementation of low temperature combustion is prohibited (S108) when cooling water temperature is blow cooling water determination temperature (NO in S104). In addition, the cooling water determination temperature is set higher as intake air temperature becomes lower, Therefore, since both the cooling water determination temperature and the intake air temperature can be considered, operating temperature conditions determining whether or not combustibility is deteriorated during low temperature combustion is accurately judged only by comparing the cooling water temperature with the cooling water determination temperature. This can effectively prevent deterioration of the combustibility of the engine. COPYRIGHT: (C)2005,JPO&NCIPI
