Dump of residual pressure in the power supply system

The preventions resulted in Section the General information and safety measures see.

During performance of the given procedure it is made only сбрасывание pressure in the power supply system. Fuel thus continues to remain in a path and components - prepare for gathering of traces of spilt fuel.


 PERFORMANCE ORDER

1. The power supply system path consists of the gasoline pump established in a fuel tank, the fuel filter, an injector of injection, the case of a throttle with the regulator of pressure built in it, and also metal tubes and rubber hoses of lines of giving and fuel return. Cavities of all listed components are filled by fuel which at the working engine and-or the included ignition is under pressure. Pressure continues to be present at system during even some time after deenergizing of ignition and before the beginning of performance of any works connected with рассоединением of a path or removal of components, should be dumped. In an ideal it is necessary to start system service only after full cooling of the engine.
2. Disconnect a negative wire from the battery.
3. Remove the relay and-or a safety lock of the fuel pump (see Has undressed Removal and installation of components of system Bosch Mono-Motronic).
4. Having disconnected the pump, temporarily connect the battery and during an order of ten seconds turn the engine a starter. If in a course проворачивания there will be an engine start, wait its spontaneous stop. The injector in process проворачивания the engine should open so much time, how many it is necessary for full сбрасывания residual pressure in the power supply system that will allow to avoid разбрызгивания some fuel at a detachment of lines of a path.
5. Take a key from the lock of ignition and disconnect a negative wire from the battery. Now it is possible to return on the place of the relay/safety lock of the fuel pump provided that the battery will remain disconnected, and ignition will not join till the moment of the termination of works.

Ignition inclusion at запитанном the fuel pump can lead unexpected разбрызгиванию fuel through apertures of the disunited lines.

6. Establish suitable drain capacity under subject to undocking штуцерное connection. Prepare enough of rags for gathering of spilt fuel.
7. Slowly ослабьте a collar or штуцерную a nut, wrap up a joint rags. When emission of the rests of fuel will stop, is definitive расстыкуйте I will corrode. Muffle the open ends of lines/unions stoppers for the purpose of minimisation of losses of fuel and in order to avoid internal pollution of the power supply system.
