A method for controlling a high-pressure pump for the injection of fuel into a combustion engine, the high-pressure pump being connected to a camshaft of the combustion engine, wherein the high-pressure pump is controlled in a camshaft-synchronous manner by ascertaining an angular offset between the flank positions of a camshaft pulse-generating wheel and a predefinable point above the bottom dead center of a cam of the high-pressure pump on the camshaft.

Method and device for controlling a high-pressure fuel pump in an internal combustion engine

In a method for operating an injector of an internal combustion engine of a motor vehicle, in which an actuator for driving a component of the injector is provided, the actuator is controlled in such a way that at least two partial injections are brought about within a working cycle of the internal combustion engine. For each partial injection, a starting point in time of the partial injection is ascertained.

Method and control unit for operating an injector of an internal combustion engine

A method is proposed for controlling an internal combustion engine having a crankshaft, in which from the angular pulses of a sensor a pulse time is formed that is a measure for the rotation of the crankshaft of the internal combustion engine per time unit. At a predetermined target angle of the crankshaft, an ignition of a spark plug and an injection of fuel are to take place. A charging of an ignition coil before the ignition and the injection each require a predetermined time duration. The charging of the ignition coil and the injection are each started before the target angle at a start time dependent on the crankshaft, the start times being calculated by taking into account the time duration of the charging and of the portion of the injection before the target angle, and the pulse time, and the pulse counter. The same pulse time is used for the calculation of the start times of the charging of the ignition coil and of the injection.
