Sbrasyvanie pressure in the power supply system of petrol engines
|
|
Remember that gasoline is extremely an inflammable liquid! At work with power supply system components observe all taken measures of fire safety. Do not smoke! Do not come nearer to a place of work with open fire or the redurable not protected by a lamp shade! Do not make system service in the premises equipped working on 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 suppose fuel hit 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 spilt fuel and do not put the rags impregnated with PETROLEUM PRODUCTS near to sources of open fire. Remember that the power supply system equipped with injection of fuel of models constantly is under pressure. Before to start a detachment of fuel lines, dump residual pressure in system. At service of components of the power supply system put on goggles. Constantly hold near at hand the class fire extinguisher In! |
As already it was mentioned above (the Power supply system see), the power supply system structure includes the electric fuel pump placed in a tank погружного, 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 be kept in system during even some time after deenergizing of ignition and before a detachment of components / undocking штуцерных sockets should be dumped.
Pressure dump in the power supply system should be carried out before service of any of its components for the purpose of minimisation of risk of ignition of fuel and reception by the executor of traumas.
Engines SOHC

- 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 painted in purple colour of the relay of the fuel pump (1).
|
|
-
Start the engine, wait its spontaneous останова, then switch off ignition.
|
|
Engines DOHC
|
|
- On the given engines besides described (Engines SOHC see above) there is an alternative way сбрасывания pressure in the power supply system (see further).
|
- Find the block of the valve (1) established on a fuel highway of the inlet pipeline. On engines of 1.4 and 1.6 l the valve is located on the right end of a highway, on engines of 1.8 and 2.0 l - in its top part.
|
|
- Turn out a cover of the valve and get under клапанную assemblage suitable drain capacity. Cover the valve from above with rags and make dump of pressure by отжимания the core of the valve a suitable screw-driver, - prepare for the fuel emission which traces I will strike collect rags. Keep the core pressed until fuel emission completely will not stop.
- In summary establish into place a cover клапанной assemblages.

All engines

- For a guarantee of completeness of a discharge of system turn the engine some more time a starter. Disconnect a negative wire from the battery.
