Definitions
- the invention relates to an electrical arrangement for controlling the idle speed of an internal combustion engine according to the preamble of the claim.
- the idling speed of a motor vehicle gasoline engine is carried out by controlling the air quantities on the intake side with an electromechanical actuator which comprises a valve element which limits the effective intake cross section and can be moved by an electric drive element (DE-OS 29 49 884).
- a lifting magnet serves as the drive element, which can adjust a piston in a cylinder against the force of a spring.
- the solenoid is loaded with an electrical variable, the control voltage, as a function of the difference between the actual idling speed and the target idling speed, in order to correct this difference by influencing the intake cross section.
- the control voltage is formed as pure direct current, for which a differential amplifier can be used.
- the direct voltage drives a direct current in the electromagnet or the lifting magnet, which generates a power loss with the coil resistance, which is converted into heat.
- the power loss increases with increasing Number of turns and decreasing wire cross-section and limits the usable force generated by it for given dimensions of the electromagnet.
- the object of the present invention is therefore to create an electrical arrangement for regulating the idle speed of an internal combustion engine of the type mentioned at the outset, in which a compact electromagnet can be operated with only a small power loss for generating a large force usable for the actuator.
- the electromagnet is thus supplemented with a capacitor connected in parallel to form a parallel resonant circuit.
- the parallel resonant circuit is operated with a special control voltage, which has a sinusoidal component with a frequency substantially equal to that Has resonance frequency of the parallel resonant circuit.
- the sine component is superimposed on a DC component, the amount of which is equal to the amplitude of the sine wave.
- the amplitude and the DC voltage component are preferably controlled as a function of the difference between the actual idling speed and the target idling speed.
- the actuating voltage contains a DC component that is superimposed on the sinusoidal excitation .
- the direct voltage component introduces the active power into the parallel resonant circuit, which is consumed by damping the coil resistance. This maintains the oscillating state of the parallel resonant circuit.
- the effective power loss caused by the hysteresis losses in the electromagnet is reduced, since due to the DC component instead of complete hysteresis loops, only Rayleigh loops in a quadrant recognize the hysteresis be passed through the line. The magnetic losses are therefore reduced.
- the eddy current losses are also reduced, so that the total undesirable heating due to direct and alternating voltage components is low for given coil properties.
- the coil is preferably operated below the saturation limit.
- a valve housing 1 is provided with a cylinder 2 in which a piston 3 is displaceable to regulate the idling speed.
- the piston forms a gap seal with its piston skirt and the inside of the cylinder.
- lateral slots 5 are formed in the cylinder, which are more or less covered by the piston skirt.
- the slots open into an annular channel 6.
- the housing with the cylinder forms a gas path for air flow from an inlet side 7 via the slots 5 and the annular channel 6 to the suction side 8 on the connector 9, see line 10.
- the connector 9 opens into an intake line 11 with a throttle cap 12.
- a lifting magnet 13 serves as an electromagnet, which is connected to the piston via a lifting rod 14 and adjusts it against the force of a spring 15.
- the lifting magnet or electromagnet 13 is connected in parallel to a capacitor 16, the terminals 17 and 18 of which are also connected to an actuating voltage source (not shown).
- the control voltage is output by a controller output block 19 - see FIG. 2.
- the control voltage depends on the control deviation xw, which is a measure of the difference between the actual idling speed and the target idling speed.
- 2 shows the parallel resonant circuit, which the capacitor 16 with the capacitance C forms with the electromagnet or solenoid 13, and its substitute sizes
- the coil current which is not shown in FIG. 3, is lagged by approximately ⁇ / 2 to the sine wave.
- both the direct voltage component and the alternating voltage component of the actuating voltage in the electromagnet or lifting magnet 13 cause only a slight heating, since active power, hysteresis and eddy current losses are low.
