6.3. 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. Power supply systems and managements), the structure of a power supply system includes 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.

|
For pressure dumping in a power supply system switch off ignition and take from the landing nest in salon the assembly block a safety lock of the fuel pump, then start the engine and wait its spontaneous останова — for dumping of residual pressure turn the engine 2-3 more times a starter, then switch off ignition and establish into place a safety lock. |
