Fuel Rail: Description and Operation
GF07.61-P-6020V Component Description Of Fuel Distribution Rail
Location
The fuel distribution pipe is located at the intake manifold above the injection valves.
Task
The fuel distribution pipe supplies fuel to the injection valves under any operating condition equally and in doing so, balances fluctuations in the fuel
pressure, for example, in case of abrupt acceleration by the fuel pressure reservoir, and its own volume.
Design
The injection valves are installed in the fuel distribution tube with an O-ring and a retaining clamp. The fuel feed at 3.8 bar system pressure is located at
the left. A pressure gauge connection is located at the right.
Function
Fuel is provided by the fuel distribution pipe in the sufficient quantity for each injection valve.
The pressure gauge connection with valve is used for testing the fuel pressure and for releasing the pressure when carrying out assembly operations.
(USA) Always install a new sealing ring after opening the pressure gauge connection.
