ABSTRACT:
Disclosed is an internal combustion engine provided with an exhaust gas recirculation system for recirculating exhaust gas from at least one but not all of the combustion chambers into an intake manifold. This internal combustion engine is also provided with an air injection system for introducing an appropriate amount of secondary air necessary for maintaining an effective exhaust gas recirculation operation. Means are provided for introducing an excessive amount of secondary air into the exhaust system at positions located near the combustion chambers including the chamber from which exhaust gas is recirculated, when the engine is operating under a warming-up condition. Accordingly, a catalytic converter located downstream of the exhaust manifold is rapidly activated just after the starting of the cold engine for oxidizing CO and HC components in the exhaust manifold.
