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.

Abstract: In a method for venting a crankcase of an internal combustion engine, in which, in a first operating range under part-load, the crankcase is vented via a first venting line, which opens into an intake line of the internal combustion engine downstream of a throttle valve, and in a second operating range under full load engine operation, the crankcase is vented via a second venting line, which opens into the intake line upstream of the throttle valve, the first venting line includes a control valve and a central unit is provided which operates the control valve so as to control the flow of vent gases through the first venting line over a range including a complete flow interruption under engine overrun condition to prevent venting gases from reaching the engine exhaust system when the internal combustion engine is operating in an overrun mode.
