A valve comprises a valve body, a flap, and a shaft driving the flap. At least one first bearing guides a first end of the shaft. The first end of the shaft includes an inner housing emerging axially. The first bearing includes a barrel axially engaged in the inner housing, such that no accumulation of condensates can occur in the inner housing when the first end of the shaft points downward.

Valve for a vehicle exhaust line

An assembly includes a heat exchanger, a bypass conduit defining a path for passage for the exhaust gases and bypassing the heat exchanger, and a valve adjusting the amounts of exhaust gases circulating through the heat exchanger and through the bypass conduit respectively. The valve has a driving shaft, and the assembly further comprises a fluid box that is in fluid communication with a heat transfer fluid circulation side of the heat exchanger and arranged around the driving shaft to cool the driving shaft.

A heat recovery device extends between an inlet and an outlet for exhaust gas, and includes a valve delimiting a direct passage for gas between the inlet and the outlet. The valve comprises a valve body housing a gate movable between a closing off position and a released position. A heat exchanger has an exchanger inlet upstream of the gate and an exchanger outlet downstream of the gate. The valve comprises a tube partially extending inside the valve body up to a mouth edge at a distal end, with the mouth edge extending in a plane. The gate has a plane contact surface configured to come in a direct contact with the mouth edge when the gate is in the closing off position.

Exhaust heat recovery device having an improved tightness

The exhaust line comprises an injection segment including at least one cup having a large upstream face directly sprayed with the exhaust gases and dividing a circulation passage into an upstream space and a downstream space. The injection segment comprises at least one circumferential conduit fluidically connecting the upstream space to the downstream space. The cup defines at least one injection channel and at least one guiding area laid out so as to guide as far as said injection channel a portion of the exhaust gases spraying the large upstream face. An injection device includes a reagent injector that is oriented to inject the reagent substantially with a co-current or counter-current of the exhaust gases in the injection channel, with the latter extending from the injector as far as the inlet of the conduit.

An ammonia generating device for treating exhaust gases of internal combustion engines, notably of automobile vehicles, includes a reservoir having a body capable of releasing ammonia by desorption and a heating device positioned inside the reservoir to heat the body in the reservoir. The heating device comprises a heat generating element that has an elongated form. The heating device further includes at least one heat transfer feature laid out along an axial direction of the heat generating element and extending in a direction radial to the heat generating element.

Device for generating ammonia

An ammonia generating device is delimited by an outer casing that includes a main reservoir and a secondary reservoir. The main reservoir is capable of reloading with ammonia the body in the secondary reservoir. A heater is capable of heating the bodies in each reservoir. A connector connects the main reservoir to the secondary reservoir. The heater comprises first and second heating devices respectively installed inside the main reservoir and the secondary reservoir and operating independently. The main reservoir is thermally decoupled from the secondary reservoir to generate a temperature gradient between both reservoirs.

A spiral exchanger has a winding axis and includes an outer sheet and an inner sheet secured to one another in a fastening plane before winding, and delimiting a space for a fluid between them. The outer sheet and the inner sheet are wound on themselves and each sheet includes a plurality of flexible areas and a plurality of rigid areas. The flexible areas are more flexible than the rigid areas during folding. The flexible areas and the rigid areas are extended along the winding axis, and at least one flexible area of the outer sheet and at least one flexible area of the inner sheet that delimit the space between them form a pair of flexible areas that are aligned in the same radial direction.

Spiral exchanger and method for manufacturing such an exchanger

An exhaust line of a motor vehicle includes an upstream monolith and a downstream monolith for treating exhaust gases passing along the exhaust line. The upstream and downstream monoliths are positioned in series. An injection portion is positioned between an upstream face defined by the upstream monolith and a downstream face defined by the downstream monolith and includes a duct through which a stream of exhaust gas flows. The duct extends from the upstream face to the downstream face and has a central line of a set length between the faces. A reagent injector is mounted on the injection portion and is designed to inject reagent in gaseous form into the injection portion. At least one cup is positioned inside the duct in the path of the exhaust gas stream so that a mean path of the exhaust gas stream line is at least 20% longer than the set length.

Exhaust line with device for injecting gaseous reagent

An exhaust line has upstream and downstream blocks for processing exhaust gases. An injection section is arranged between an upstream face defined by the upstream block and a downstream face defined by the downstream block and includes a circulation channel for the exhaust gas flow extending from the upstream face to the downstream face. The channel includes a central line having a determined length between the upstream and downstream faces. The injection section includes a reagent injector capable of injecting a reagent into the injection section. The injection section has a first cup inside the circulation channel in the flow path such that the average path of exhaust gas jets is higher by at least 20% in relation to the predetermined length. A second cup is arranged inside the circulation channel between the upstream face and the first cup. The reagent is done between the first cup and the second cup.
