Toyota RAV4>> Fuel system and system of production of the fulfilled gases>> General information
The power supply system of the engine consists of a fuel tank, the electric fuel pump, a regulator of pressure of fuel, the block of the EFI relay, the relay of the fuel pump, the distributive fuel highway, nozzles, the air filter and throttle knot and топливопроводов. All models are equipped with consecutive electronic system of injection of fuel (Sequential Electronic Fuel Injection system).
The consecutive electronic system of injection of fuel counts quantity and submits fuel to engine cylinders as their work. Nozzles cope the engine (PCM) control unit. On the basis of information from various sensors, the PCM block the block operates fuel nozzles, changing length of an impulse, i.e. an interval of time when nozzles are open. The amount of fuel constantly changes to provide an optimum ratio for start of the hot or cold engine, warming up, an idling and acceleration mode. The throttle knot serves to operate only amount of the air submitted to cylinders of the engine.
Fuel from a fuel tank to fuel system moves on the metal tubes fixed under the bottom of the car. The electric fuel pump, the fuel level sensor and a regulator of pressure are located in a fuel tank.
The relay of the fuel pump copes on two electric chains. On the first chain management is carried out from the control unit by the engine (PCM), and on the second — from the ignition lock. If after inclusion of ignition engine start is not carried out, the PCM block will disconnect the relay of the fuel pump through 2 pages. At the following start of the engine, after the first impulse from the sensor of provision of a camshaft, the relay turns on the fuel pump.
The system of production of the fulfilled gases consists of a final collector, a reception exhaust pipe, the central and back exhaust silencers and catalytic converter. Catalytic converter carries out purification of the fulfilled gases.
