ABSTRACT:
An internal combustion engine is comprised of a gas injecting device injecting gas into the combustion chamber of the internal combustion engine, and a gas injection control device controlling the gas injecting device, wherein the gas injection control device provides control such that the gas is injected toward the combustion chamber for a period of time after flame extinguishing timing and before exhaust valve closing timing. Therefore, the internal combustion engine is capable of reliably combusting HC, CO, smoke, and so forth remained in a combustion chamber due to a quenching phenomenon or the like.
