ABSTRACT:
In a fuel injection system for a multicylinder internal combustion engine, particularly a V8 engine, including a high pressure fuel pump supplying high pressure fuel to a high pressure fuel supply duct serving as a high pressure fuel storage (common rail) from which high pressure fuel distribution lines extend to magnetic valve-controlled fuel injectors associated with the various cylinders of the engine, the distribution lines have an inner diameter of at least 2.99 mm and a length of less than 122 mm with an inner diameter to length ratio of between 1:36 and about 1:41 to reduce pressure oscillations in the fuel system.
