Abstract

The present invention relates to a method for controlling the opening speed of a valve connected between a fuel tank and a filter and configured to release pressure within the fuel tank into the filter, the method Including the following steps: - measuring the pressure in the fuel storage tank; - measuring or inferring the fuel vapor temperature in the fuel storage tank; - calculating the opening speed according to the pressure in the fuel storage tank and the fuel vapor temperature; - The valve is opened at the calculated opening speed to avoid blockage of another valve of the fuel tank connected between the valve and the fuel tank. The invention also relates to an assembly for implementing the method.

Description

technical field [0001] The present invention relates to isolation valves for fuel tanks in the automotive industry. Background technique [0002] Fuel tank vapor and emission control systems are used to control the flow of fuel vapor from the vehicle fuel tank and also to control the relative pressure of the fuel tank. The vapors are vented to a carbon canister or other vapor control structure where hydrocarbon vapors are stored and also connected to the engine air inlet. [0003] The fuel storage tank produces fuel vapors during various phases of operation that are directed to a carbon canister or other component responsible for storing them and then periodically scavenging them to the intake head of the engine. During vehicle operation, stored vapors must be periodically purged. To control this scavenging, the fuel system is operated to control the flow of vapors from the storage canister to the engine air inlet, and to allow ambient air in to scavenge the canister. [...
