Embodiment Construction

[0036] In the following description, specify generally:

[0037] The term "bypass" corresponds to the action of the device to divert the flow away from the main duct by deflecting the passage to avoid the main duct.

[0038] The term "cylinder inlet" defines the part of the cylinder at which intake takes place, for example the part at the intake valve ("soupape") for the gases being combusted.

[0039] The term "cylinder outlet" defines a portion of a cylinder at which exhaust gas occurs, for example, a portion at a gas exhaust valve for exhausting burned gas to an exhaust line.

[0040] The term "exhaust gas" defines the combusted gas that is expelled at the outlet of the cylinder. Exhaust gases can either be directed to the exhaust line or recirculated towards the cylinder inlet, especially in the case of dedicated cylinders.

[0041] Embodiments of the invention relate in particular to the intake gas excess supply and exhaust gas recirculation system 3 .

Abstract

The invention concerns a system (3) for supercharging the intake gases and for recirculating the exhaust gases of an engine (1), comprising: a supercharging circuit (5) comprising a turbocharger (9) to be driven by the exhaust gases from at least a first cylinder (2a, 2b, 2c) of the engine (1); a recirculating circuit (7) for the exhaust gases from at least a second cylinder (2d); and an exhaust gas-orienting device (25) which is connected to the two circuits (5 and 7) and is intended to be connected to an exhaust line (23) of the engine (1) so as to control an amount of exhaust gas placed in communication between the supercharging circuit (5), the recirculating circuit (7) and the exhaust line (23) of the engine (1).

Description

technical field [0001] The invention relates to the field of internal combustion engines, in particular engines for driving motor vehicles, equipped with an exhaust gas recirculation ("ExhaustGasRecirculation (EGR)" in English) circuit, which is used in at least one Engines on dedicated cylinders. In other words, the outlet of the dedicated cylinder is directly connected to the inlet of the gas recirculation circuit. Background technique [0002] It is known from the prior art to recirculate part of the exhaust gases into the intake air, especially at light engine loads, in order to reduce the amount of polluting emissions or fuel consumption. [0003] For each type of engine (differentiated by technology used, power, regulation, etc.), the acceptable range of recirculation ratio varies with the parameters of the engine (rotational speed, temperature, etc.). Exceeding acceptable ranges results in a loss of engine efficiency, so it should be possible to vary the recirculati...
