The invention relates to a plate for a heat exchanger, said plate comprising an edge () for coupling to another plate. According to the invention, said edge has at least one fusible component () for joining this coupling edge () to at least one casing wall, said at least one fusible component () being configured to be separated from the rest of said coupling edge by differential expansion/contraction between said plate and said at least one casing wall to which it is intended to be joined.

Heat exchanger plate, and heat exchanger comprising such a plate

A plate () for a heat exchanger () is stackable with another plate () of the heat exchanger () to form a pair of plates (). The pair of plates () are arranged to permit the circulation of a fluid to be cooled between the pair of plates (). The plate () exhibits an exchange zone (ZE) to encourage the exchange of heat with the fluid. The plate () also exhibits a bypass zone (ZBP) capable of allowing the fluid to bypass the exchange zone (ZE). The plate () comprises means () originating from the plate () configured in such a way as to force a circulation of the fluid in the exchange zone (ZE). A core () of plates comprising a plurality of the plates (), as well as a heat exchanger () comprising the core (), are also disclosed.

Heat exchanger plate with bypass zone

The invention relates to a device for mixing a stream of supercharging air and a stream of recirculated exhaust gases. The device comprises a manifold allowing the stream of air and the stream of recirculated gases to be mixed, and allowing the mixture to be distributed in the cylinder head. The device also comprises means for conveying the recirculated exhaust gases in the manifold that allow the distributed injection of the recirculated exhaust gases into the stream of supercharging air. The device additionally comprises means for thermally insulating the conveying means in order to limit the cooling of the recirculated exhaust gases by the supercharging air.

Device for mixing a stream of inlet gases and of recirculated exhaust gases comprising insulating means for the recirculated exhaust gases

Disclosed is a recirculated exhaust gases distribution device () of an inlet manifold () for an air inlet module configured to supply at least one internal combustion engine cylinder with a flow of air containing inlet gases and/or recirculated exhaust gases (EGR gases), the distribution device () including a recirculated exhaust gases distribution duct (), the distribution duct () including first means () for injection of recirculated exhaust gases into the flow of air for supplying at least one cylinder. The distribution device () further includes a control member () that is arranged in the distribution duct () and is configured to modulate the flow of recirculated exhaust gases injected by the first injection means ().

The invention relates to a device for the injection of recirculated exhaust gases from a vehicle engine, in particular a diesel engine, the injection device comprising a plurality of injection ports (), provided in a portion of the material of the injection device, each injection port () having a cross section and a height extending through the thickness of the material. According to the invention, the cross sections and/or the heights of at least two of the injection ports () are different.
