Embodiment Construction

[0030] figure 1 and 2 An exhaust gas purification and recirculation device 10 is shown, which is intended to be arranged, in particular, in an exhaust system of a motor vehicle.

[0031] The purification and recirculation device 10 has an upstream pipe 12 extending in a first direction X1. This upstream pipe 12 is intended, for example, to be connected to the outlet of a turbocompressor of the exhaust system, usually a turbocompressed engine, or to the outlet of the exhaust manifold of an atmospheric engine. The upstream pipe 12 is made of stainless steel, for example.

[0032] The upstream pipe 12 receives at least one exhaust gas cleaning component 14 , for example two cleaning components 14 connected in series.

[0033] Thus, the upstream pipe 12 performs the cleaning function of the cleaning and recirculation device 10 .

[0034] The purification and recirculation device 10 also has a first downstream pipe 16 extending in a second direction X2 in which at least one con...

Abstract

The present invention relates to a device for purification and recirculation of exhaust gas (10). The device includes an upstream pipe (12), extending along a first direction (X1), and in which at least one purification member (14) is housed, a first downstream pipe (16), extending along a second direction (X2), and in which at least one heat exchanger (18) is housed, and a second downstream pipe(28) configured to be connected to an exhaust gas outlet tube. The device also includes an intermediate chamber (30) comprising an exhaust gas inlet (32) communicating with the upstream pipe (12), downstream from the at least one purification member, a first exhaust gas outlet (34) communicating with the first downstream pipe, and a second exhaust gas outlet (36) communicating with the second downstream pipe (28). The first direction and the second direction form an angle between them comprised between 0 degrees and 90 degrees.

Description

technical field [0001] The invention relates to an exhaust gas purification and recirculation device, in particular for motor vehicle exhaust systems. Background technique [0002] Exhaust gas purification and recirculation devices are used in particular to reduce the fuel consumption of heat engines, in particular of motor vehicles. [0003] A purification and recirculation device known from the prior art, especially according to FR 3 041 033 A1, is relatively heavy and difficult to install in the exhaust gas line. [0004] The present invention aims especially to overcome this drawback by providing a compact exhaust gas cleaning and recirculation device. Contents of the invention [0005] To this end, the invention relates in particular to an exhaust gas purification and recirculation device, in particular for use in an exhaust system of a motor vehicle, the exhaust gas purification and recirculation device having: [0006] - an upstream pipe extending in a first direc...
