Abstract

In an internal combustion engine of the crossflow type, a cylinder head is formed therein with an exhaust gas recirculating passage which opens at one end in the inner peripheral surface of the exhaust port, wherein the open end is directed at a predetermined sharp angle with respect to the same inner peripheral surface and in a direction reverse to the direction in which the flow of exhaust gases is introduced into the exhaust port. Further, at least part of the exhaust gas recirculating passage extends in the vicinity of at least one cooling water jacket formed within the cylinder head. Thereby, recirculation of an excessive amount of exhaust gases can be prevented and the temperature of exhaust gas recirculated can be lowered.
