Distribution pipe

 

 

 

The distribution pipe is built into the fuel line to the cylinder head. Its function is to evenly distribute the fuel to the pump / injectors at a uniform temperature.

 

 

From the supply line, the fuel moves through the center of the distribution pipe to the cylinder 1 at the far end. The fuel also moves through the transverse holes in the distribution pipe and enters the annular gap between the distribution pipe and the cylinder head wall. This fuel is mixed with hot unused fuel, which is returned to the supply line by a pump-injector. This creates a uniform fuel temperature in the supply line to all cylinders. All injector pumps are equipped with the same mass of fuel, and the engine runs smoothly.
