Abstract

The invention concerns a magnetic valve controlled fuel injection device for internal combustion engines, in which a fuel pump is driven by a drive element from the cylinder head camshaft and is located separately from a fuel nozzle and connected thereto by a relatively short exposed injection pipe; and wherein the fuel pump or nozzle forms a structural unit jointly with the magnetic valve, which controls the beginning and end of pumping as a function of operating parameters of the internal combustion engine; and wherein this unit is secured to the cylinder head in such a way that at least one casing part of the aid pump, facing away from the drive element, and the magnetic valve are located outside the space enclosed by the cylinder head and the cylinder head cover.
