Fuel Rail: Description and Operation
GF07.61-P-6020KE Component Description Of Fuel Distribution Rail
- up to model year 08
Arrangement
Component Identification
The fuel distribution tube is mounted at the left of the cylinder head.
Task
^
Injection valves should be supplied with equal amounts of fuel under all operating conditions.
^
Fuel pressure pulsation damping
^
Facilitate testing and reduction of fuel pressure
Design
Component Identification
The fuel injection valves are inserted in the fuel distribution rail with an O-ring and a retaining clamp.
Function
The pressure measuring connection and valve makes it possible to test the fuel pressure for diagnostic purposes and to reduce the fuel pressure during
installation work.
The fuel pressure damper reduces fuel pressure pulsation when bleeds fluctuate highly.
