6 — the Delivery chamber of an air path


The power supply system consists of the fuel tank placed in it of the electric fuel pump, the relay of the fuel pump, the fuel highway with injectors of injection, a regulator of pressure of fuel, assembly of an air purifier and the throttle case. All models described in the real Management are equipped with electronic system of injection of fuel.

System of programmed injection of fuel (PGM-FI)

In PGM-FI system electric impulses of accurately limited duration are used for management of fuel injection through injectors directly to the inlet port of each of chambers of combustion of the engine. The moment and duration of time of opening of each of injectors supervises the module of management of functioning of the power unit (RSM). RSM continuously traces various working parameters of the engine and on the basis of arriving information defines the demanded volume injected in each of inlet ports of fuel. The throttle case in this case serves only for management of giving in an air power supply system. In view of that each of cylinders is equipped with own injector, this scheme provides possibility of very exact management with structure of an air and fuel mix.

Fuel pump and gasoline pipe lines

Supply of fuel from a fuel tank in system of injection and return of its surplus back in a fuel tank is carried out on two metal lines laid under the bottom of the car. The electric fuel pump is located by Pogruzhna in a fuel tank and united in uniform assembly with the block of the sensor of fuel consumption. The system of return of fuel evaporations carries out branch паров fuel back in a fuel tank on the separate returnable line. Access to assembly of the gasoline pump/sensor of fuel consumption is carried out through a luggage compartment of the car by dismantle of a plastic cover.

The main PGM-FI relay (the relay of the fuel pump) is fixed on an arm under the dashboard from the driver's party of the car, is more left than a steering column. Management of functioning of the relay is carried out by some various electric contours. On one of these contours from the lock of ignition tension of the battery moves. The second contour is connected to RSM which makes one-second short circuit of the relay. In the course of a provorachivaniye of the RSM engine carries out relay short circuit on weight until the sensor of position of pistons (CYP) will not give out the corresponding signal (see. Head Engine management). In the absence of basic impulses within two-three seconds there is a pump shutdown. The third contour disconnects the relay at the released pedal of coupling (model with RKPP), or at the lever of the AT selector deduced from the position "R". Protection of this contour against overloads is provided with a safety lock on 7.5 And.

System of production of the fulfilled gases

The system of production of the fulfilled gases of the V6 models consists of pair of final collectors, a Y-shaped reception pipe, the catalytic converter with the oxygen sensor (l-probe) located behind it, the exhaust silencer and an exhaust pipe. On 4-cylinder models the design of system of production of the fulfilled gases is even simpler, as the catalytic converter incorporates a reception pipe to the unique final collector of the engine.

The catalytic converter is one of the main components of system of decrease in toxicity of the fulfilled gases. On considered models one-section converters with the 3-functional catalyst are used.
