Vapour from the fuel tank flows through two float valves (1) to separator (2). Vapours that condense in the separator fall into the tank.Uncondensed vapours are sent to canister (4) through multifunction valve (3) and a special pipe. Here they are absorbed and stored in by the active carbon inside.The vapours flow on to the intake manifold through solenoid (5) controlled by the injection-ignition control unit.
