System of electronic injection of fuel (EFI) – the general information

Cars Toyota Land Cruiser considered in the present Management are equipped by system of electronic injection of fuel (EFI), consisting of three basic subsystems: systems of distribution of giving of fuel, system подмешивания air and an electronic control system.

System of distribution of giving of fuel

The electric fuel pump is placed in a petrol tank and provides a constant pressure of giving of fuel in a fuel highway. In a fuel highway fuel is in regular intervals distributed between injectors which inject it directly into inlet ports of chambers the combustion located over inlet valves. Management of quantity of fuel injected into the engine carries out the electronic module (ЕСМ). The special regulator carries out pressure updating in the power supply system depending on depth of depression in the inlet pipeline. The fuel filter is established between a gasoline pump and a fuel highway and serves for protection of components of a path against pollution.

System подмешивания air

The system structure includes an air cleaner, the throttle case, and an air sleeve connecting listed components. The special gauge (gauge IAT) continuously traces temperature of air soaked up in the engine, sending the corresponding information on ЕСМ which considers it at definition of duration of the impulses operating opening of injectors. Management of position throttle заслонки in the throttle case is carried out by the driver by means of a gas pedal. At opening заслонки speed of giving of air increases that leads to decrease in temperature of a stream. IAT immediately notifies ЕСМ on the occurred changes therefore the module in due time corrects fuel giving.

Electronic control system

The microprocessor electronic module of management (ЕСМ) exercises administration of functioning of systems of injection, ignition and decrease in toxicity of the fulfilled gases. Accepting signals from set of information gauges and analyzing the received information, ЕСМ constantly supervises such working parametres of the engine as temperature of soaked up air, degree of opening throttle заслонки, the temperature of a cooling liquid, turns of a cranked shaft, speed of movement of the car, the oxygen maintenance in the fulfilled gases, etc. On the basis of the analysis of arriving information ЕСМ defines duration of opening of the injectors, providing optimum by the current moment time structure of an air-fuel mix. The part of information gauges and the relay of their management are not included directly into structure of system of injection of fuel and are scattered on an impellent compartment of the car. More detailed description of a principle of functioning and design of components of a control system and ЕСМ is resulted in the Head of the Control system by the engine and decrease in toxicity of the fulfilled gases.
