Abstract

In a multicylinder internal combustion engine with cylinder banks arranged in the shape of a V wherein a single cam shaft is supported centrally within the V space between the cylinder banks and push rods are disposed in push rod guides formed alongside the two cylinder banks so as to be operable by the cam shaft for actuating inlet and outlet valves of associated cylinders via rocker arms, fuel injection pumps are supported in mounting openings formed into the cylinder banks along the sides thereof so as to be also operable by the cam shaft for the injection of fuel into the cylinders via injectors mounted to the cylinders, the push rods and the fuel pumps are also arranged in V-shaped rows along the cylinder banks and coolant channels extend along each cylinder bank between the cylinders and the fuel pumps wherein, a cross-sectional plane extending through a particular cylinder, the pump mounting openings, the coolant channels, the push rod guides and the associated cylinder are disposed in a fan-like arrangement.
