1080E EVAPORATION SYSTEM

OPERATION

The fumes from the tank are sent to the canister (2), where they are absorbed and stored in carbon filters, through a multi-function valve (1).

They reach the intake manifold through solenoid valve (3) controlled by the injection-ignition ECU.

MULTI-FUNCTION VALVE

The purposes of the multi-function valve are:

• - to close the valve when the tank is full
• - to open the valve to send fumes to the canister
• - to ventilate the tank if a vacuum is created
• - to impede spilling fuel if the vehicle rolls over.

Closed valve with full tank
Float (2) blocks hole (9) blocking the flow of fuel to the canister thus protecting it from damage.
