Patent ID: 7389770

Claim:
An apparatus for supplying recirculated exhaust gases to incoming air of a piston-type internal combustion engine, said apparatus comprising: a duct ( 2 ) for incoming air and a feed pipe ( 1 ) for exhaust gases and which includes an outlet section ( 3 ) inside the duct ( 2 ); said outlet section ( 3 ) comprising at least one outlet ( 4 ) for distributed supply of exhaust gases and said outlet section ( 3 ) constitutes an outlet path (a) that extends in the longitudinal direction of the duct ( 2 ) and the length of which is longer than an inner diameter of the feed pipe ( 1 ), wherein the at least one outlet ( 4 ) is plurality of elongated outlets ( 4 ) distributed along a circumference running transversely to the motional direction of incoming air in the form of substantially parallel slots in the longitudinal direction of the duct ( 2 ); and said outlet path (a) has a length that is at least twice as long as the inner diameter of the feed pipe ( 1 ) whereby it is possible for an exhaust-gas pulse transported through the feed pipe ( 1 ) to be distributed into a portion (a 1 ) of incoming air which, in the duct ( 2 ), passes the outlet section ( 3 ).
