The EGR (Exhaust Gas Recirculation) pipe (14) is connected at its upstream end (18) to the engine exhaust pipe or silencer (20). Its downstream end (22) is connected to the inlet air box (16) from which air mixed with exhaust gases flows to the engine (12). The second end of the EGR pipe is surrounded by a sleeve which passes through part of the air inlet passage. The sleeve is sealed at its ends, by O-rings, to the walls of the induction tract and the inlet air box. The end off the EGR pipe is sealed inside the sleeve. |
