ABSTRACT:
An air guide casing includes an air filter, an air throttle valve, an exhaust gas recycling pipe, a mixing chamber in fluid communication with the recycling pipe, and a distributor chamber in fluid communication with the mixing chamber and at least one cylinder of an internal combustion engine. The air guide casing is provided with means for collecting a mixture of recycled exhaust gas and filtered intake air and means for distributing that mixture to the cylinders. Thus, the air guide casing provides a separate mixing section in the air guide casing to achieve good mixing of the air for combustion with the incoming exhaust gas prior to introduction of the exhaust gas and clean air into the distributor chamber.
