Definitions
- the invention relates to a method for controlling an ignition system for internal combustion engines according to the preamble of claim 1.
- a generic ignition system is from the DE-OS 39 28 726 known, compared to conventional Ignition systems, for example so-called transistor ignitions with static high-voltage distribution, has the advantage that small and therefore cost-effective Ignition coils are used. Furthermore, according to the o. G. Document ensuring the optimal ignition thereby that they are independent for the entire burning time from the speed, remains on. Such Ignition system is referred to as AC ignition system, because it generates a bipolar spark current.
- a likewise a bipolar ignition current generating Ignition system describes the DE-OS 24 44 242, after which after generation of a spark the spark plug with a relatively small Voltage of the sparking current for a certain period of time is maintained. This is done by means of a Multivibrators a transistor during each ignition period so clocked that thereby in the secondary winding the ignition transformer is a relatively constant Voltage of, for example, 3 kV is induced, the sufficient, at the spark plug a voltage of more as to generate 800 V, which is required to spark current uphold if this before was built.
- the spark burning time can be this way be chosen, as is the requirements of the internal combustion engine equivalent.
- the object of the present invention is therein, a method for controlling an ignition system specify according to the type mentioned, so that the spark plug replacement intervals at least 100,000 km.
- This task is characterized by the characterizing Characteristics of claim 1 solved.
- hereafter is the value of the spark current and its Burning time depending on the motor parameters Motor load and speed controlled.
- Ignition current map stored in a control unit a base value for the value of spark spark current and from one also in the controller stored burn duration map a base value for the burning time taken.
- Such ignition with controlled parameters causes a much lower Burning on the spark plugs as a common one Series ignition. This will change the spark plug replacement intervals significantly extended.
- these basic values for the Zündstromwert and the Burning time according to the current operating state the internal combustion engine corrected. So a temperature compensation is performed if the engine temperature is a certain threshold has not reached yet. This will cause the cold start feature of the engine improved.
- the underlying asset for the Zündstromwert at a dynamic Change of state of the motor with a dynamic Factor applied proportional to the load value change is and decreases with time. After a certain Delay time has the dynamic factor Value zero is reached, with the corrected base value the Underlying for the new load state.
- the process according to the invention can be advantageous for controlling AC or high voltage capacitor firings be used.
- FIG. 1 shows a block diagram of an AC ignition for carrying out the method according to the invention for a 4-cylinder engine.
- an ignition output stage Z1-Z4 is provided for each spark plug ZK1.
- These ignition output stages are connected via a circuit 9 for cylinder selection with a control unit 1, which generates an ignition signal 1 to 4 for each ignition output stage and simultaneously outputs a modulation voltage U Mod for all ignition output stages, which is processed by a current control circuit 10.
- This modulation voltage sets a target value of the ignition current I is intended to represent and is by means of a comparator with an on a shunt resistor R (see FIG. 2) of the primary circuit of the ignition actual value I generated is compared. The result of the comparison is supplied to the cylinder selecting circuit 9.
- control unit 1 with sensors 4, 5 and 6 for detecting the rotational speed n, the load L and the engine temperature T and with a device 7 for cylinder 1 detection and via lines 1a for controlling the electronic injection with an injection system 11, which contains the corresponding actuators connected.
- a switching power supply 3 generates the supply voltages (18 V / 180 V) for the ignition output stages Z1-Z4, which is supplied by an on-board battery 2.
- FIG. 2 An embodiment of an ignition output stage for driving a single ignition coil of Figure 1 is shown in Figure 2 and consists essentially of a transistor T, in the embodiment of an IGBT transistor (insulated gate bipolar transistor), an energy recovery diode D, a primary resonant circuit capacitor C. , One composed of a primary and secondary winding coil Tr with a coupling of about 50%, a spark plug ZK and a simple control circuit 10, which corresponds to the current control circuit 10 of Figure 1, but additionally includes a gate of the cylinder selection circuit 9.
- This control circuit 10 are therefore supplied to the prepared by the control unit 1 control signals, namely the ignition signal 1 and the modulation voltage U Mod .
- the first-mentioned control signal sets the ignition time and the burning time t B
- the second-mentioned control signal U Mod defines the value of the primary current I p and, as a result, the ignition voltage U k , ie the value of the spark current i B.
- the generation according to the invention of these two control signals ignition signal 1 and U mod will be explained below.
- the ignition output according to the figure 2 operates in current-controlled blocking and fürflußwandler horr.
- a collector current I k flows , which corresponds to the primary coil current I p according to FIG.
- This collector current I k is limited by the control circuit 10 to a value determined by the modulation voltage U mod I soll .
- the ignition output stage is supplied with a already explained in connection with the figure 1 switching power supply with a voltage of 180 V. If the collector current I k has reached the value predetermined by I soll , the transistor T is switched off. The energy contained in the storage coil excites the output circuit (secondary inductance, spark plug capacitance) to oscillate.
- the capacitively stored energy is again fed to the primary coil inductance until the voltage U c at the capacitor C reaches zero (see FIG. 3).
- the primary-side voltage U c can not be negative by the diode D.
- the oscillation continues because of the only approx. 50% strong coupling between primary and secondary inductance.
- the transistor T is turned on again, because now there are the same voltage conditions as before the first turn on of the transistor. Power control always guarantees the same energy input into the primary coil. The portion of the injected energy that was not needed in the spark channel is completely fed back into the electrical system.
- the coupling of approx. 50% prevents total attenuation of the primary resonant circuit (primary coil, capacitor C) due to the strongly attenuated secondary resonant circuit in the event of a spark break.
- the duration of the complete cycle (charging of the primary coil, decay operation up to the zero crossing of the voltage U c across the capacitor C) is about 80 ⁇ s.
- the charging time of the coil can be neglected. Therefore, in contrast to the transistor coil ignition, a closing angle control is not required.
- the burning time t B per ignition process can be changed as desired by the variation of the number of switching cycles.
- the modulation of the spark-burning current i B takes place via the change in the primary-side fed energy.
- the secondary-side high-voltage supply U k at the spark plug ZK also changes in certain areas in parallel to the spark-burning current. In the reduction of the spark current i B thus also the decrease of the maximum high voltage must be considered in each case.
- This technique of self-oscillating ignition output leaves a significant reduction in volume the ignition coil, because in contrast to the transistor coil ignition not all the energy for one Ignition must be stored in the coil, but replenished in several small units. For storing the smaller amount of energy is therefore only a reduced coil volume needed.
- Another advantage for the structure of the ignition coil is the needed coupling of only about 50%, since this with a simple rod core can be realized.
- the control unit 1 represents a ⁇ -controller system, for example, based on a Motorola device MC68HC811E2, which is an 8-bit controller with internal EEPROM program memory.
- the power supply of this control unit 1 takes place from the electrical system powered by the battery 2.
- the control unit 1 requires a signal about the cylinder sequence (Cylinder 1 detection 7 according to Figure 1).
- Cylinder 1 detection 7 For this purpose, for example, on the toothed wheel to attach a magnet to the camshaft, which is queried by a Hall sensor. This delivers all 360 ° of the camshaft or every 720 ° of the crankshaft a signal: the cylinder 1 mark.
- the AC ignition system according to FIG. 1 becomes an ignition system, which makes it possible to control the ignition energy with the aid of two parameters.
- the first parameter is the modulation voltage U Mod , by means of which the primary current I p (see FIG. 2) of the ignition coil is regulated. With this current I p , the high voltage U k of the secondary coil or the spark current i B , with which the spark burns, influenced.
- This is a higher-frequency PWM signal, which is smoothed via an RC filter in the ignition output stage and which is output jointly for all 4 cylinders, as shown in FIG.
- the control unit 1 has a PWM output.
- the individual cylinders are ignited with the ignition signals 1 to 4.
- the burning time t B of the ignition process represents the second parameter and is also determined by the control unit 1 and realized over the pulse width of the respective ignition signal.
- the control program stored in the control unit 1 for the ignition output stages ensures, on the one hand, the correct ignition distribution and, on the other hand, the calculation of the optimum ignition parameters, namely in the form of the modulation voltage U Mod and the burning time t B and their output.
- the control unit 1 Before the triggering of the ignition output stages can begin, the control unit 1 must be synchronized, ie, it waits for the first signal of the cylinder 1 detection of the device 7 (see FIG. This is followed by an infinite loop in which all calculations are performed and repeated at each ignition. In this loop, an analog-to-digital conversion is performed to detect the engine parameters generated by the sensors 5 and 6, such as load and temperature. The speed is determined by evaluating the time interval between successive pulses of the speed sensor.
- the new ignition parameters are calculated, for which purpose from two stored in the memory of the control unit 1 maps the corresponding base values U base and t basis of the modulation voltage U Mod and the burning time t B are taken. These two maps are shown in Figures 4 and 5, namely the fuel flow map and the ignition duration map. The interpretation of these maps depends on the ignition energy requirements.
- the characteristic diagram for the spark-burning current i B according to FIG. 4 takes into account the offered current with a safety factor of 1.2. The highest current at idle speed is required regardless of the load.
- U Mod U Base + U Temp + U dyn .
- U base is the base value determined from the load-speed map
- U Temp is the temperature correction value
- U Dyn is the dynamic correction value.
- T 70 ° C is a certain threshold temperature, for example 70 ° C
- T is the current engine temperature
- k T is a proportional factor.
- the temperature correction is a proportional correction, that is, the motor temperature falls below a certain threshold, ie z. B. 70 ° C
- a factor U Temp is calculated by which the modulation voltage U Mod is increased. This factor U Temp is proportional to the difference between the motor temperature and the temperature threshold. When the engine is warm, this correction is not performed.
- t B t Base + t Temp .
- t basis is the combustion duration base value determined from the load-speed characteristic map
- T is 70 ° C a certain threshold, for example 70 ° C and T is the current engine temperature, while k Tt as in the corresponding temperature correction of the modulation voltage U Temp is a proportionality factor.
- the temperature is taken into account only when the engine temperature T is below the threshold temperature, that is, for example, of 70 ° C.
- the electrode burn of these spark plugs was over a factor of 3.9 smaller than the one with the the series ignition operated spark plugs.
