Fuel conduits in the cylinder block of an internal combustion engine and method for constructing same

摘要

In a fuel line arrangement in the cylinder housing of an internal combustion engine with cylinders arranged in line and upstanding mounting structures with support bores for the reception of plug-in fuel injection pumps formed on the sides of the cylinders a fuel return passage extends through the cylinder housing so as to intersect all the fuel pump support bores, a fuel supply passage extends through the cylinder housing parallel to the fuel return passage and oblique passages extend between the fuel supply passages and the respective fuel pump support bores for supplying fuel to the plug-in pumps within the fuel pump support bores, the oblique passages being arranged such that their outward extensions are within the confines of the fuel pump support bore top opening to facilitate drilling of the oblique bores.
