2.6.22. Check of quantity of fuel submitted the fuel pump (атомобили with 4 cylinder engine FSI)
The minimum pressure of the accumulator 12,5 Century
The fuel filter should be serviceable.
The fuel tank should be filled not less than on 1/4.
Ignition is switched off.
Procedure for test
Open a cover of the block of safety locks on the left side of the instrument panel.
Take out a safety lock from pads safety locks (the left number, 5th big safety lock from above).
Connect remote control with the help адаптерного a cable to the right plug of a socle.
Connect the tightening plug to the plug (+) АКБ the car.
Turn off a cover of a jellied mouth of a fuel tank.
Remove an engine casing.
The fuel system is under pressure. Before system opening wrap up pure rags a junction. Then, slowly turning off a junction, pit pressure.
Disconnect submitting pipeline 1 from a place of its connection to the engine (fig. 2.277
|Fig. 2.243. Installation of the device of measurement of pressure with adapters
Connect a manometre by means of adapters to submitting топливопроводу
Connect an auxiliary hose to a manometre and lower other end in a measured vessel.
Open запорный the manometre crane. The lever should be turned in a stream direction.
Create in fuel system preliminary pressure, having pressed for this purpose the switch of remote control and slowly closing запорный the manometre crane.
Preset value: superfluous pressure 4 bars.
After that position of the crane do not change.
Empty a measured vessel.
Press the switch of remote control and keep its pressed during 15 with.
|Fig. 2.275. The diagramme of the minimum volume of fuel submitted in fuel knot
Compare the received volume of fuel to the minimum volume on the diagramme (sm3/15) (fig. 2.275
Pressure on the fuel pump at the idle engine and the working pump approximately on 2 In more low pressure АКБ.
Assemblage is carried out in return sequence, thus it is necessary to execute the following.
The inhaling moment
Топливопровод to the fuel distributor: 22 Н·м.
