- the common rail integrated into the wall of a cylinder head cover arranged on the internal combustion engine. It is considered advantageous in the cited document that the manufacturing and Assembly effort reduced and the common rail rail against vibrations and Damage is arranged protected. It seems disadvantageous, however, that disassembly of the Do not remove the cylinder head cover without loosening the one connected to the common rail High pressure lines is possible.
- An internal combustion engine is known from EP 0637 687 A1, in which fuel is supplied to single injection pumps in the form of plug-in pumps as fuel feed and Fuel return channels in the form of holes in the cylinder housing Internal combustion engine are provided. However, these fuel channels are only used for supply and discharge of the fuel to the plug-in pumps, but it is not a Injection system with a common rail.
- an internal combustion engine is known from US Pat. No. 3,845,748, in which a fuel injector is arranged in a first bore in the cylinder head of the internal combustion engine and one to the Fuel injector leading tube to supply fuel in a second through the Cylinder head leading bore is arranged, which is at right angles to the first bore runs.
