Toyota RAV4>> Fuel system and system of release of the fulfilled gases>> The general data
The engine power supply system consists of a fuel tank, the electric fuel pump, a regulator of pressure of fuel, relay EFI block, the relay of the fuel pump, a distributive fuel highway, atomizers, the air filter and throttle knot and топливопроводов. All models are equipped by 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 cylinders of the engine as their work. Atomizers cope the block of management of the engine (PCM). On the basis of the information from various gauges, block PCM the block operates fuel atomizers, changing length of an impulse, i.e. an interval of time when atomizers are opened. The quantity of fuel constantly changes to provide an optimum parity for start of the hot or cold engine, warming up, an idling and acceleration mode. The throttle knot serves to operate only quantity of 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 gauge of level of fuel and a pressure regulator 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 engine management block (PCM), and on the second — from the ignition lock. If after ignition inclusion engine start is not carried out, block PCM will disconnect the relay of the fuel pump through 2 with. At following start of the engine, after the first impulse from the gauge of position of a camshaft, the relay includes the fuel pump.
The system of release of the fulfilled gases consists of a final collector, a reception exhaust pipe, the central and back mufflers and catalytic neutralizer. Katalitichesky neutralizer carries out clearing of the fulfilled gases.
