Definitions
- the invention is based on a method for controlling an injection valve for an internal combustion engine, a voltage pulse being applied to a solenoid coil of the injection valve.
- the object of the present invention is to provide a method for controlling the injection valve, in which the valve is opened as soon as possible after the voltage pulse provided to open the valve begins.
- This object is achieved in that before the voltage pulse, a lower current than is required to open the injection valve flows through the solenoid.
- the measures according to the invention ensure that a magnetic field that is sufficient to open the injection valve builds up in the shortest possible time after the start of the voltage pulse.
- a further development of the invention consists in that a pulsating voltage is supplied to the magnetic coil before the voltage pulse is applied. This further development enables the current flowing before the opening process to be limited without any appreciable power loss occurring.
- the solenoid coil of the injection valve is acted upon by a voltage pulse 1 shown in FIG. 1.
- the current I increases gradually through the inductive component of the magnetic coil until a value given by the voltage and the resistance is reached. After the voltage has been switched off, the current decays in the form of a damped oscillation, with the half-wave highlighted in hatching remaining remanent magnetization in the opposite direction.
- the current I begins at 0 after the voltage is switched on and takes the course shown in dashed lines in FIG. 2.
- the energy supplied is first used for a magnetic reversal of the magnetic core, so that a field strength required for opening the valve is only reached later.
- the voltage pulse 1 provided for opening the injection valve is preceded by voltage pulses 2, 3, 4, which bring about the current shown in FIG. 2 as a solid line.
- the magnetic core is already remagnetized at the beginning of the voltage pulse 1, so that the opening process is considerably accelerated.
- circuit arrangements known per se For example, circuit arrangements for limiting the current to a value sufficient to keep the injection valve open for low-resistance injection valves are known. These circuit arrangements can also be used, appropriately controlled, for limiting the current I before the valve is opened.
