Abstract
The present invention relates to a four-cycle internal combustion engine in which a strong swirl can be generated within the combustion chamber through the directionality of the mixed gas supplied from the main suction path and the injection of a gas from the sub-suction path, and a heavier EGR than before can be carried out without detracting the engine performance, and NOx generation can be substantially reduced by EGR alone. In time of idling when a heavy EGR is needless, the gas injection from the sub-suction path is controlled to prevent a misfiring.
