2.6.5. Decrease in a high pressure of fuel
|Fig. 2.228. A shtekernyj socket of the valve of a regulator of pressure of fuel
Remove штекерный a
socket 2 by means of the adjusting tool from the valve of a regulator of pressure of fuel (fig. 2.228
Leave the engine to idle прибл. During 10 with.
By means of removal штекерного a socket from the valve of a regulator of pressure of fuel idling pressure of fuel прибл. About 50 bar decreases прибл. To 6 bar.
Fuel pressure drop can be observed, if the diagnostic tester is connected and the block of management of the engine is chosen. Then by means of function Consider the block of measured sizes to choose group of indication 140.
In the field of indication 3 pressure of fuel (current value) will be displayed.
Switch off ignition.
After high pressure decrease it is possible to open high pressure system, for this purpose it is necessary to wrap up pure rags a junction to dump residual pressure in the fuel system, making прибл. 7 bar. Collect following fuel.
If a highway of a high pressure not to disconnect immediately, pressure of fuel can raise a little again.
Connect a diagnostic tester and generate in a mode Conducted search of malfunctions a readiness code in the block of management of the engine.
