Abstract:
A driving device comprises a support, an actuator provided with an output shaft and fixed to the support, and an arm having a distal point provided to be connected to the closing member. A kinematic chain converts a rotation of the output shaft into a rotational movement of a proximal point of the arm around a rotation axis. The proximal and distal points are situated at opposite ends of the arm. The kinematic chain comprises a link connecting the arm to the support. The link is arranged to guide the proximal point of the arm in rotation around the rotation axis, and to transmit, between the arm and the support, radial orientation forces relative to the rotation axis.
Abstract:
An ammonia generating device is used for the treatment of exhaust gases of internal combustion engines, particularly for motor vehicles. The device includes a tank having a body capable of releasing ammonia by desorption. The device is also provided with a first single connection member comprising an electrical connection to supply the device with electricity and a fluid connection to allow evacuation of the ammonia produced following the desorption reaction.
Abstract:
A heating device includes conductive elements, positive and negative electrical terminals, first and second connecting parts each including a first part that is a substantially planar longitudinal part extending in a longitudinal direction, a second connecting part connected to the first part while extending transversely to this first part, the second part being connected to a respective one of the terminals, and at least one third part, connected to the first part while extending transverse to this first part. Each conductive element has one end connected to the second or third part of one of the first and second connecting pieces, and another end connected to the second or third part of the other first and second connecting piece.
Abstract:
A device includes a power source, at least one exhaust gas purification member having an upstream face and a downstream face, and a heating member placed in front of and at a distance from the upstream or downstream face. The heating member comprises a frame and a plurality of elongate heating elements surrounded by a peripheral part of the frame. Each heating element has first and second ends, with at least one of the first and second ends being electrically connected to the power source with the other end being connected to the frame. Each heating element is, between the first and second ends, connected only to at least one other of the heating elements. The heating elements are in contact with one another by respective points of contact, two points of contact of two different heating elements in contact with one another being at the same electric potential.

Abstract:
A purification method comprises providing a purification device comprising at least one exhaust gas purification member having an upstream surface through which the exhaust gas enters the purification member and a downstream surface through which the exhaust gases exit the purification member. The method further includes, in the absence of forced circulation of the exhaust gas through the purification member by an engine of the vehicle, heating radiatively at least either the upstream zone or the downstream zone, for example before starting the engine of the vehicle.
Abstract:
A device for storing and supplying ammonia to an exhaust line of an automobile vehicle, includes a solid material provided for absorbing the ammonia, a reservoir for storing the solid material, and a heating unit to heat the solid material to desorb the ammonia. The solid material comprises solid elements with a mass of less than 50 grams. The heating unit is insulated from the reservoir. The device also includes a first assembly for transferring solid elements from the reservoir to the heating unit.
