Definitions
- the invention relates to a device for suppressing unwanted ignitions in a gasoline engine according to the preamble of claim 1.
- a device for suppressing unwanted ignitions in a gasoline engine is known from EP 0 370 301 AI.
- the ignition coil is energized by means of an ignition output stage in the control of a gasoline engine, a voltage is induced on the secondary side of the ignition coil by the switching flank when the primary circuit is switched on, which voltage is capable of an ignition spark in certain operating states of the gasoline engine to produce on the spark plug, which can lead to an undesired ignition of the gasoline-air mixture and engine damage due to a premature ignition.
- An ignition coil is a floating system, which is made up of inductors and parasitic capacitors. If this system is subjected to a switch-on flank, the secondary winding is excited into a damped oscillation, which can reach a voltage amplitude that is almost twice as high as the voltage determined by the transmission property of the ignition coil.
- the aim is therefore to slow down the switching on of the ignition coil in such a way that no oscillation is excited and the secondary voltage thus only assumes the voltage value determined by the transmission property of the ignition coil.
- the object of the invention is to design such a device in such a way that it manages with significantly smaller capacitance values of the capacitor.
- the single figure shows a starter output stage of a gasoline engine, not shown, in which the primary winding 7a of an ignition coil 7 is arranged in series with an ignition switch 6 between positive pole + U and negative pole GND of an on-board voltage source 9, and the secondary winding 7b of which is connected to at least one spark plug 8.
- the ignition switch ⁇ is designed as a so-called IGBT (I_solated-gate-bipolar-T_ransistor), which corresponds to a Darlington circuit of a MOS and a bipolar transistor.
- the control connection (gate connection G) of the ignition switch 6 is connected via a first resistor 2 to a control circuit 1 which supplies a control signal st for the duty cycle of the P ⁇ marstro circuit.
- This control circuit is generally a microcontroller of an engine control unit used for controlling the functions of the gasoline engine, which is assigned a defined internal resistance by the first resistor 2.
- a series connection of a capacitor 4 connected to the collector connection C and a second resistor 5 is arranged between the collector connection C of the ignition switch 6 and the negative pole GND; and between the gate terminal G and the connection point of capacitor 4 and resistor 5, a current-conducting diode 3 is arranged away from the gate terminal.
- This configuration allows the circuit to be easily integrated into integrated circuits.
- the device described works as follows: when the ignition switch 6 is not conductive, the capacitor 4 is charged to the voltage U of the on-board voltage source 9.
- Emitter terminal E of the ignition switch 6 goes towards zero.
- the falling collector-emitter voltage U CE causes one
- the edge of the collector-emitter voltage U CE is limited in its “slew rate”.
- the ignition switch 6 is operated as an amplifier in the time domain of the rising primary current (the falling collector-emitter voltage U CE ).
- Diode 3 a negative feedback via capacitor 4.
- the circuit according to the invention requires a delay of the falling edge of the collector-emitter voltage U CE of 100 ⁇ s
