Fuel Rail: Description and Operation
The fuel rail assembly is made up of the left hand rail (5), which delivers fuel to the even cylinders (2,4,6); the right hand rail (1), which delivers fuel to
the odd cylinders (1,3,5); the fuel injectors (4), and the fuel pressure regulator assembly (3) which are mounted to the lower section of the intake
manifold and distributes fuel to the cylinders through the individual injectors.
Fuel is delivered to the fuel inlet tube (2) of the fuel rail by the fuel pipes. The fuel then goes through the fuel rail to the fuel pressure regulator. The fuel
pressure regulator maintains a constant fuel pressure at the fuel injectors. Remaining fuel is then returned to the fuel tank.
