6.5. The control of allocation of steams of fuel

THE GENERAL DATA

Control system of allocation of steams of fuel

1 – a cover of a jellied mouth, 2 – the canister for charcoal, 3 – a hose, 4 – a calibrated aperture, 5 – a hose,

6 – the electromagnetic valve of cleaning, 7 – the gauge of temperature of a cooling liquid, 10 – the safety valve

To minimise leak in atmosphere of not burnt hydrocarbons, on later models the control system выделений fuel steams is used. The cover of a jellied mouth of a fuel tank is tight, therefore in the canister with charcoal the petrol steams formed in a fuel tank of the parked car gather. The canister stores fuel steams until they will not leave from the canister through the electromagnetic valve of cleaning. When the valve is opened, fuel pass of steams to the treatise of giving of air to the engine is opened also steams are burnt at engine work.

To guarantee that the engine works normally, at the cold engine or idling ECU does not open regulating valve of cleaning while the engine has not heated up, and does not allow reserved steam to pass in the treatise of giving of air in the engine.
