Catching system паров fuels

The catching system паров fuels prevents evaporation паров fuels in the atmosphere from a fuel tank therefore formation of a photochemical smog is prevented.

Pairs of fuel accumulate in the canister with absorbent carbon. At operation of the engine the electronic control unit opens the valve, and pairs of fuel arrive in the engine where there is their combustion.

The control valve is used for management of pressure паров fuels in a fuel tank.

Scheme of system of catching паров fuels

System of ventilation of a case (PCV)

The valve of system of ventilation of a case copes the depression created in an inlet collector at operation of the engine.

At operation of the engine on frequency of rotation of idling, the valve is open slightly therefore a small amount of karterny gases is taken away in the resonant chamber and further дожигается in engine cylinders.

At increase to frequency of rotation of the engine, extent of opening of the valve therefore the amount of karterny gases which is taken away in the resonant chamber and further дожигается in engine cylinders increases increases.

System of a retsirkulyatsiya of the fulfilled gases (EGR)

For reduction of emissions with the fulfilled gases of an oxide of nitrogen, the system of a retsirkulyatsiya submits a small amount of the fulfilled gases to an inlet collector, thus there is their reburning in cylinders of the engine and the temperature of combustion of a fuel mix decreases. On Sephia/Shuma cars specially developed new linear EGR valve is established. This valve carries out functions of the electromagnetic valve of a retsirkulyatsiya of the fulfilled gases and the management valve. On the basis of signals from the control unit, the valve operates amount of the fulfilled gases submitted to the engine at the expense of the core moving which situation is defined depending on information received from sensors of provision of a butterfly valve, a measuring instrument of a consumption of air and the sensor of temperature of cooling liquid.
