FAURECIA SYSTEMES D'ECHAPPEMENT

A heating device comprises first and second electrodes attached to a heating plate comprising a plurality of branches each having a proximal end turned from a first longitudinal side of the heating plate and a distal end turned from a second longitudinal side of the heating plate. The branches are separated by slits each opening to at least one longitudinal end. The proximal end and/or distal end of each branch is connected to the proximal end and/or distal end of an adjacent branch. The electrodes are connected to the proximal ends of a first intermediate branch of the intermediate branches and a second intermediate branch of the intermediate branches respectively.

A protective cover for an electrical conductor comprises a substantially tubular cap surrounding the electrical conductor. The protective cover further includes a substantially disc-shaped flange comprising a bore surrounding the electrical conductor in a liquid-tight manner and an outer contour strictly inscribed in an inner contour of the tubular cap facing disc-shaped flange. The tubular cap also comprises at least one perforation arranged at a low point of the tubular cap. In one example, the protective cover is used for a heating element for an exhaust line.

A heating element for an exhaust line includes a substantially tubular housing that defines a passage section for the exhaust gases and at least two heating discs arranged across the passage section to force the exhaust gases to pass through the at least two heating discs. A connector supports the at least two heating discs and provides an electrical connection between the at least two heating discs.

A base for a pressurized gas tank, such as hydrogen, is substantially circular about an axis, and comprises a substantially cylindrical pipe of axis, which passes through the base in order to connect an outside of the tank to an inside of the tank. A substantially tubular notch of axis is arranged on an inner side of the tank and is suitable for receiving a sealing envelope. A substantially tubular sleeve of axis is arranged on the inner side of the tank and has an inner diameter substantially equal to a diameter of the pipe and an outer diameter substantially equal to an inner diameter of the notch, and also has an axial extension at least equal to that of the notch. An O-ring and a groove of axis, capable of receiving the O-ring, are arranged in a side wall of the notch. The base also comprises a body and a substantially tubular ring of axis, interfaced by a surface of revolution about the axis passing through the groove.

A protective device for a pressurized gas tank comprises a shell designed to absorb energy in the event of an impact and a mechanical joining interface to mechanically join the shell to the pressurized gas tank.

A device for fastening a tank to a vehicle is provided. The tank is substantially in the form of a cylinder with an axis arranged substantially horizontally. The device comprises at least two substantially identical, substantially flat frames, substantially perpendicular to the axis, comprising an opening presenting a shape substantially identical to a section perpendicular to the axis of the tank so as to be able to enclose, at least partially, the tank. The device further includes a fastening interface to the vehicle and an impact energy dissipation feature that dissipates impact energy transmitted to the tank according to a substantially horizontal direction substantially perpendicular to the axis. The impact energy dissipation features is arranged between the opening and the fastening interface.

A head for a pressurised gas tank comprises a structure having an opening, a head comprising a base disposed in the opening, and a valve assembled with the base. The base comprises a boss disposed outside the tank, at least one first channel comprising an axial part along the axis which is not open connected with the inside of the tank, and at least one radial part. The at least one radial part is pierced radially in the boss until the radial part joins the axial part. The valve has a substantially annular shape comprising a first bore corresponding to the boss in order to be able to be engaged on the boss, and at least one second channel, one end of which opens into the first bore axially in line with said at least one radial part. A tank comprising such a head is also provided.

A tank for pressurized gas such as hydrogen, comprises a paste sealant, a sealing envelope, and a base comprising a recess accommodating a neck. A substantially annular external cavity is between a convex surfaces of the neck and a concave surfaces of the recess A substantially annular inner cavity is between a concave surface of the neck and a convex surface of the recess. The paste sealant occupies the annular external and annular inner cavities uniformly and thus ensures the mechanical strength and the gas seal between the sealing envelope and the base. The sealing envelope comprises a body and a neck on the surfaces of which at least two angularly equidistant protrusions extend radially.

A protective device for a pressurized gas tank comprises a shell designed to absorb energy in the event of an impact and a mechanical joining interface to mechanically join the shell to the pressurized gas tank.

An injection and mixing device comprises a casing having an exhaust inlet and an exhaust outlet, the casing internally defining a passage for exhaust gases from the exhaust inlet to the exhaust outlet. The exhaust inlet opens into an inlet region of the passage. The injection and mixing device further includes an injector of a liquid comprising a nitrogen oxide reducing agent or a precursor of such a reducing agent. A deflector is housed within the casing and defines in the passage a first passage connecting the inlet region to the exhaust outlet, in which the exhaust gases flow at a first average velocity, and a second passage connecting the inlet region to the exhaust outlet, in which the exhaust gases flow at a second average velocity lower than the first average velocity, The injector injects liquid into the second passage.
