ABSTRACT:
A cross-flow type internal combustion engine having an exhaust gas recirculating passage formed in the cylinder head. The passage is located adjacent to cooling water jackets so that the gas in the passage is cooled by the water in the jackets. The passage is formed with an expansion chamber which is also located adjacent to the cooling water jackets and the intake ports. Due to the cooling effect in the passage, water content in the recirculated gas is condensed and separated from the gas. Further, the gas flow speed is decreased in the expansion chamber so that carbon particles in the recirculated gas can be separated therefrom.
