Embodiment Construction

[0029] figure 1 The exhaust line 1 shown in is arranged to be connected to an engine 3 of a motor vehicle.

[0030] The exhaust line comprises, from upstream to downstream in the exhaust gas flow direction: a manifold 5 arranged to capture the exhaust gases leaving the combustion chamber of the engine; a turbo compressor 7; catalytic purification elements (not shown); and other devices not shown, such as mufflers. At its downstream end, the exhaust line includes a sleeve (not shown) capable of discharging the purified exhaust gas to the atmosphere.

[0031] The manifold 5 comprises an inlet flange 9 for fixing to the engine, a casing 11 and an outlet flange 13 for fixing to the turbo compressor 7 .

[0032] The inlet flange 9 is rigidly fixed to the cylinder head 15 of the engine.

[0033] The housing 11 internally defines an exhaust gas flow passage 16 having four inlets 17 and one outlet 19 . Each inlet 17 is arranged to be placed to coincide with the exhaust gas outlet ...

Abstract

An exhaust line connected to the engine of an automobile, includes: a manifold (5) including at least one exhaust gas circulation channel (16) having an exhaust gas outlet (19), the manifold (5) including an outlet flange (13) through which the exhaust gas outlet (19) extends; a downstream apparatus (7) having an exhaust gas inlet (27) connected to the exhaust gas outlet (19) of the manifold (5), the downstream apparatus (7) being rigidly connected to the outlet flange (13) of the manifold (5). The engine (3) includes an engine block and a cylinder head (15), and the exhaust line (1) includes attachment elements (33) for attaching the outlet flange (13) of the manifold (5) directly to the engine block or the cylinder head (15).

Description

technical field [0001] The present invention generally relates to exhaust lines for motor vehicles. [0002] More precisely, the invention relates to an exhaust line provided for connection to an engine of a motor vehicle, the exhaust line being of the type comprising: [0003] - a manifold having an exhaust gas flow channel internally with an exhaust gas outlet, said manifold comprising an outlet flange pierced by the exhaust gas outlet; [0004] - a downstream device having an exhaust gas inlet connected to the exhaust gas outlet of the manifold, the downstream device being rigidly fixed to the outlet flange of the manifold. [0005] The downstream device is typically a turbo compressor, itself connected to a catalytic purification element. Both devices are of considerable mass. Background technique [0006] In FR2856735, a support structure is provided to secure the catalytic purification element and the turbocompressor to the engine block. This support structure rece...
