Abstract: A system for storing an ammonia precursor, comprising a tank, a filler pipe equipped With an obturator and a ventilation line establishing a direct connection between the filler pipe and a gas discharge duct and also a device designed to specifically open this connection once the obturator starts to be opened.

Abstract: System for storing an additive solution and injecting it into the exhaust gases of an internal combustion engine, the system comprising a tank for storing the additive and a rotary pump, a metering valve and an injector which are separate devices, this system making it possible to meter and inject the additive solution into the exhaust gases as is, without diluting it with a gas. In this system, the pump outlet pressure is regulated by adjusting the rotational speed of the pump. Process using such a system.

Abstract: A heater for heating a fluid intended to pass through a fuel tank canister is provided. The heater includes a casing provided with a coupler for coupling to the canisters, at least two plates placed inside the casing in substantially parallel planes, and at least one heating element housed between the plates. The at least two plates are place inside the casing such that the fluid flows between the two plates. The coupler is placed in a plane substantially parallel to at least one plane of one of the plates and the projected area of the coupler on the plane of one of the plates lies substantially within the projected area of the casing on the plane.

Abstract: Heater for a fluid intended to pass through a canister for a fuel tank, comprising a casing fitted with two end pieces, a hollow body situated inside the casing and at least one heating element.

Abstract: A fuel vapor storage and recovery apparatus for a fuel system of a motor vehicle including an internal combustion engine with an exhaust pipe and a fuel tank containing a fuel vapor/air mixture above a liquid fuel, the exhaust pipe being close to the fuel tank. The apparatus includes a vapor storage canister including a fuel vapor adsorbent material therein, a thermal insulation mechanism for thermally insulating at least a portion of the fuel tank from the heat generated by the exhaust pipe, and a beat exchanger. The heat exchanger is configured to heat to a purge temperature air guided there through by absorbing heat from the thermal insulation mechanism.

Abstract: A fuel system for an internal combustion engine and including a fuel tank, a filler tube for filling the tank, and a pump for supplying the engine with fuel. The pump is fastened to the filler tube. A fuel trap is integrated to the filler tube, the fuel trap lying at the bottom of the fuel tank and including the fuel pump inside or on top of it.
