Fuel guidance system for a multicylinder internal combustion engine having inlet bores for connector pumps

A fuel guidance system for an internal combustion engine having in-line cylinders arranged in a cylinder housing, the fuel guidance system comprising:

• inlet bores arranged in the cylinder housing;
• connector pumps which are received in said inlet bores, said connector pumps being solenoid valve controlled;
• high pressure lines extending between said connector pumps and associated injection valves of the internal combustion engine:
• a supply line extending over a length of the cylinder housing and being connected with said connector pumps;
• control valves associated with said connector pumps which control flow connections between said supply line and said high-pressure lines;
• at least one feed line associated with a connector pump that connects said supply line and leads to a low-pressure side of an associated control valve;
• wherein said supply line runs as a continuous fuel supply line either in said cylinder housing so as to one of intersect and tangentially connect with said inlet bores, or running separately outside said cylinder housing;
• and
• wherein said supply line is a through flow bore and is tangent to said inlet bores at a level of an annular chamber formed by each inlet bore and connector pump.
