Sbrasyvaniye of pressure in a power supply system of petrol engines

Remember that gasoline is extremely inflammable liquid! At work with components of a power supply system observe all taken measures of fire safety. Do not smoke! Do not come nearer to a venue of works with open fire or unprotected by the lamp shade carrying! Do not make system service in the rooms equipped with working at natural gas and heating devices equipped with a control torch (such as водогреи and dryers for clothes). Do not forget that gasoline is among cancerogenic substances, i.e., - the substances promoting development of a cancer!

Try not to allow fuel hits on open sites of a body, - use rubber protective gloves, at casual unforeseen contact to fuel carefully wash hands warm water with soap. Immediately collect the spilled fuel and do not put the rags impregnated with a fuels and lubricants near sources of open fire. Remember that the power supply system equipped with injection of fuel of models constantly is under pressure. Before starting a detachment of fuel lines, dump residual pressure in system. At service of components of a power supply system put on goggles. Constantly hold near at hand the class B fire extinguisher!

As it was already mentioned above (see. The power supply system), is included into structure of a power supply system the electric fuel pump placed in a tank pogruzhny, the fuel filter, injection injectors, a regulator of pressure and the connecting listed components fuel lines. Fuel in a power supply system path at the working engine and the included ignition is under pressure. Residual superfluous pressure continues to keep in system during even some time after switching off of ignition and before a detachment components / undocking of shtutserny sockets should be dumped.

Pressure dumping in a power supply system should be carried out before service of any of its components for the purpose of minimization of risk of ignition of fuel and receiving by the performer of traumas.

SOHC engines


  1. Make sure that ignition is switched off, uncover the assembly block established in an impellent compartment — the block is behind the top support of the left rack of a suspension bracket. Take from the landing nest the relay of the fuel pump (1) painted in purple color.
  1. Start the engine, wait its spontaneous останова, then switch off ignition.

DOHC engines


  1. On these engines besides described (see above SOHC Engines) there is an alternative way of a sbrasyvaniye of pressure in a power supply system (see further).
  1. Find the block of the valve (1) established on the fuel highway of the inlet pipeline. On l engines 1.4 and 1.6 the valve is located on the right end of the highway, on l engines 1.8 and 2.0 - in its top part.
  1. Turn out a cover of the valve and get under klapanny assembly suitable drain capacity. Cover the valve from above with rags and make pressure dumping by an otzhimaniye of the core of the valve a suitable screw-driver, - prepare for the fuel emission which traces I will strike collect rags. Hold the core pressed until fuel emission completely will not stop.
  2. In summary establish into place a cover of klapanny assembly.

All engines


  1. For a guarantee of completeness of a discharge of system turn the engine several times a starter. Disconnect a negative wire from the battery.
