ABSTRACT:
An engine control device is configured to cause an engine to operate at the optimum combustion mode according to the load when warming up of an emissions purification catalyst is required, and to obtain reduced HC discharged from the engine and accelerated warm-up of the catalyst. The engine control device performs stratified combustion with a compression stroke injection in a low-load region according to the engine load, and performs double-injection combustion with an intake stroke injection and a compression stroke injection in an intermediate load region, when warming up of the catalyst is required. In a high-load region, the engine control device performs homogenous combustion with an intake stroke injection.
