摘要:
A device for exhaust gas recirculation for a combustion engine is provided that includes an exhaust gas pipe configured to conduct exhaust gas and a channel configured to conduct air to the combustion engine. The exhaust gas pipe terminates in the channel, wherein the exhaust gas pipe, in an area of insertion in the channel exhaust, is in thermal exchange with a coolant from a coolant circuit.

An air intake tract arrangement for an internal combustion engine includes an exhaust gas inlet device arranged at the inlet side of a charge air cooler and configured to direct injected EGR exhaust gas substantially in a direction towards an inlet of said charge air cooler, thereby enabling the use of plastic intake tract components.
摘要:
A self-cooling exhaust gas injection device making it possible to inject heated gases, for example recycled exhaust gases from an internal combustion engine, into the air intake distributor of this engine, characterized in that it comprises a return pipe for the exhaust gases (1) which extends in the distributor (2) to the downstream end thereof in the direction of the transfer of the recycled gasses and is equipped in this area with a series of outlet orifices (4) positioned so as to uniformly distribute these gases between each of the cylinders of the engine.

摘要:
An intake system (10) of an internal combustion engine includes an intake manifold (12) with at least two feed pipes (14) connected with cylinder head intake ports of the internal combustion engine and includes at least one intermediate chamber (30) having connections (34) to an interior volume (24) of each feed pipe (14). Each connection (34) can be opened or closed by way of an intake control valve (49) having a switch chamber (48) which has a connection (60, 62) to means for creating a pressure in the switch chamber (48). The switch chamber (48) is separated from the interior volumes (24) of the feed pipes (14) and the intermediate chamber (30) by a diaphragm (50).

摘要:
Disclosed is a device for swirling and mixing exhaust gases recycled in the intake duct (1) of an internal combustion engine via a recycling conduit (2). The device is formed of two control flaps (3, 4) in the form of toroidal portions, mounted rotatably about axes of articulation (6, 7), the control flaps (3, 4) being displaceable in rotation between, on the one hand, a rest position in which they are retracted along the inner wall of the intake duct (1) so as to expose the entire cross-section of said duct and, on the other hand, an active position in which they are pulled towards one another so as to reduce said cross-section, and also formed of an actuator which makes it possible to control displacement of the control flaps (3, 4) between the active position and rest position thereof.
