Abstract
A control system for an engine comprises an operation range judging section that judges an operation range assumed by the engine, a variable cycle operating section that switches the operation of the engine between 4-cycle operation and a different cycle operation in accordance with a judgment made by the operation range judging section, the different cycle operation being of an operation whose cycle is different from 4-cycle, and an intermediate variable cycle operating section that allows part of the cylinders to carry out 4-cycle operation and remaining part of the cylinders to carry out the different cycle operation when the operation range judging section judges that the engine is under an intermediate operation range assumed between an operation range provided by 4-cycle operation and an operation range provided by the different cycle operation.
