摘要：
A device at an intake system for internal combustion engines incorporating a return conduit (17) for exhaust gases between exhaust side and intake side, in said return conduit a valve (18) controlled by the engine speed, a connection flange (16) between engine block (10) and inlet manifolds (14), said connection flange having through openings (14′) for intake air to the cylinders (1-6), and an exhaust channel (17′) arranged in the connection flange along the edge thereof, means for connecting the exhaust channel via said valve (18) to the engine exhaust side, said exhaust channel having branch conduits (20), communicating with the different through openings (14′). The connection flange is equipped with a further internal channel (19′) extending along the exhaust channel (17′), but between this and the side of the connection flange (16) facing the inlet manifolds (14), and which further channel (19′) is connected to an outlet tube (11) forming part of the intake system before a throttle valve (12) provided therein for supply of air to the further channel (19′).
