6.9. System of electronic injection of fuel

Management cистемой fuel injection is carried out by the onboard microcomputer named the processor block (ECM-block).

In the electronic block of management the information from the various gauges tracing such working parametres of the engine as volume and temperature of sucked in air arrives, the temperature of a cooling liquid, engine turns, a mode of dispersal or braking by the engine, concentration of oxygen in the fulfilled gases etc. Signals are used by the electronic block of management for correct definition of duration of injection of fuel. On the basis of the data received from gauges, the management block defines optimum duration of injection of fuel.

In default the gauge the reserve scheme simulating the faulty gauge which provides preservation of road performance of the car before malfunction elimination joins. Repair and adjustment of system of injection is carried out in car-care centre.

Observe following safety rules:

  – Before a detachment of any sockets always disconnect a safety pillow (subsection 11.23 see), disconnect the battery from weight;
  – At installation of the storage battery observe polarity of connection of cables;
  – It is forbidden to subject to strong blows of a detail of system of electronic injection of fuel and system of decrease in toxicity during removal or installation;
  – Be accurate during search of malfunctions (even short-term short circuit of conclusions of sockets can lead to wrong results of check or to failure of one of numerous schemes);
  – It is forbidden to repair independently the processor block, or to open a cover of the case of the block;
  – Do not suppose water hit on system gauges at their survey during rainy weather;
  – At a sink of a compartment of the engine avoid water hit on gauges and sockets of system of injection.
