摘要： Disclosed is a spark ignition type internal combustion engine, which comprises a variable compression ratio mechanism capable of changing a mechanical compression ratio, and a variable valve timing mechanism capable of controlling the closing timing of an intake valve. The intake air flow to be fed to the inside of a combustion chamber is controlled mainly by changing the closing timing of an intake valve so that the mechanical compression ratio is set higher at an engine low-load running time than that at an engine high-load running time. The mechanical compression ratio at the engine low-load running time before completion of the warm-up of the internal combustion engine is set lower than that at the engine low-load running time after completion of the warm-up of the internal combustion engine. Although the expansion ratio at the engine low-load running time is raised to improve the mileage, it is possible at an engine cold start to heat an exhaust purifying catalyst promptly and to suppress the deterioration of an exhaust emission.

摘要： A spark ignition type internal combustion engine of the present invention is provided with a variable closing timing mechanism which can change a closing timing of an intake valve after suction bottom dead center wherein the amount of intake air fed into a combustion chamber is controlled mainly by changing the closing timing of the intake valve. At the time of engine cold start, the closing timing of the intake valve is advanced compared with the time of engine warm operation. At the time of engine cold start, the air-fuel mixture which is taken into a combustion chamber is blown back into the engine intake passage whereby the air-fuel ratio varies among cylinders, but according to the spark ignition type internal combustion engine of the present invention, it is possible to suppress such variation in the air-fuel ratio among cylinders.
