Check of serviceability of functioning of system of injection of fuel

See preventions at the beginning of pressure Sbrasyvaniye's section in a power supply system of petrol engines.


  1. Check reliability of fastening of electric connections of a chain of system of injection, special attention giving to a condition of plugs of grounding. Attentively examine all systems concerning functioning electric sockets. Violation of quality of electric contacts involves a set of problems and of more than a half of engine failures is at the bottom.
  2. Check level of a charge of the battery. Accuracy of management of structure of an air and fuel mix to a great extent depends on serviceability of functioning of ECM and the information sensors, defined, including, and level of tension of their food.
  3. Check a condition of a filtering element of an air purifier (see. Head Routine maintenance), - even partial violation of passableness of the air filter makes essential impact on profitability of fuel consumption and efficiency of return of the engine.
  4. If the safety lock of system of injection is beaten out, replace it, - if the new safety lock also fails at once, address to schemes of electric connections (see. Head Onboard electric equipment) also check the corresponding electric chain on existence of signs of short circuit on weight.
  5. Check connecting air purifier and the inlet pipeline an air sleeve on existence of signs of development of the leaks conducting to violation of correctness of configuration of an air and fuel mix. Also check a condition of the vacuum hoses connected to the inlet pipeline.
  6. 6 Disconnect the air sleeve going from the case of a throttle and check the last on existence of traces of a nagaroobrazovaniye and other deposits (in particular on sites near a butterfly valve). In case of identification of signs of pollution of a throttle see. Systems of release and decrease in toxicity of the fulfilled gases also make diagnostics of malfunctions of systems of ventilation of a case (PCV) and a retsirkulyatsiya of the fulfilled gases (EGR). Process a throttle one of types of the special cleaning aerosols suitable for the use on equipped with catalytic converters and a lambda probes of cars, wipe the processed surfaces pure rags.
  1. At the working engine serially hear by means of a stethoscope to each of injection injectors, - the uniform poshchelkivaniye testifies to serviceability of functioning of an injector. In the absence of near at hand stethoscope, use a long screw-driver, simply pressing a tip of her sting to the case of an injector and being guided by vibrations transferred on the handle.
  1. At identification of signs of violation of functioning of an injector it is necessary to use a special lamp sampler (ask in shops of automobile accessories). The lamp is connected to the electric socket of a suspected injector. Start the engine and test a lamp all injectors. The uniform blinking of a lamp confirms serviceability of functioning of a component. Otherwise the car should be driven away on car repair shop for more detailed diagnostics.
  1. Muffle the engine, disunite electric sockets of injectors and measure electric resistance of each of them. Compare results of measurements to standard requirements, - demanded value makes 12 — 16 Ohm. Faulty injectors are subject to replacement.
  1. Check self-diagnostics system on existence of the codes which were stored in her memory of malfunction (see. Head engine Electric equipment).

It is necessary to charge performance of more detailed diagnostics of a condition of system to specialists of the car-care center, having all (rather expensive) equipment necessary for this purpose.

Skilled motorists in the presence of a certain knowledge and the corresponding equipment (including a tachometer and the calibrated gas analyzer) can check the content in the fulfilled gases of monooxide of carbon (WITH) and quantity of turns of idling. Nevertheless, if checked parameters demand carrying out adjustments, them it is necessary to charge performance to specialists of the car-care center, having the expensive special diagnostic and adjusting equipment.
