Definitions
- the invention relates to an inductive coil ignition system for an engine with at least one ignition coil, the one powered by a voltage source, primary winding having two connections and a secondary winding which also has two connections includes.
- Inductive coil ignition systems for engines, in particular Automotive engines are well known.
- Ignition coil used in such systems has one Primary winding on periodically with a primary current is applied. This current is used for Build up a magnetic field in the coil that acts as an energy storage should serve. At the desired ignition point the primary current is interrupted. The in Magnetic field stored energy then ensures a steep rise in voltage on the secondary winding with the result of a flashover in the spark plug and a correspondingly steep rise of the secondary current.
- the one stored in the coil magnetic energy flows continuously as electrical Energy in the sparks.
- the ion current measuring method Since the ion current measuring method has expired Requires ignition sparks, it is in the known Ignition systems where the secondary current is slow subsides, cannot be used. For example, to record the tendency of an engine to knock rather, other more complex measuring systems are necessary.
- the inductive coil ignition system with the features of claim 1 has the advantage that enables the use of an ion current measuring method, so that an affordable overall solution is achievable. Because a parallel to the primary winding arranged switching device to one predeterminable time the two connections of the Primary winding electrically connects, the magnetic Energy in the coil through the primary winding degraded so that the secondary current drops abruptly. Due to this drop in power goes out the ignition spark, so that immediately afterwards an ion current measurement is possible. That parallel to the primary winding arranged switching element is about a control input from one in a special Control circuit generated control signal driven.
- FIG. 1 shows an inductive coil ignition system 1, which is used to control a spark plug 3, the for example assigned to a cylinder of a motor vehicle engine is.
- Essential part of such Coil ignition system is a coil 5, the one Has primary winding 7 and a secondary winding 9.
- a connection side 11 of the primary winding 7 is on the positive pole of a DC voltage source, preferably one battery connected, the other Terminal 13 to the collector of a transistor T2, whose emitter is grounded.
- the transistor T2 is preferably a triple Darlington transistor.
- the base of the transistor An ignition signal A is applied to T2.
- Terminal 15 of the secondary winding 9 On the secondary side of the coil 5 is a first one Terminal 15 of the secondary winding 9 with one pole connected to the spark plug, the other pole of which is grounded lies.
- the Anode is connected to ground.
- a switching element is parallel to the primary winding 7 19, for example a thyristor, whose one terminal 21 with the terminal 13 and whose second connection 23 with the first connection 11 of the primary winding is connected.
- One Control input 25 of the switching element 19 becomes a control signal supplied by a control circuit 27 is generated.
- the control circuit 27 is controlled via a control signal B.
- An ion current measuring device 31 is assigned to the secondary side of the coil 5 and measures an ion current flowing over the candle after the ignition spark has gone out. On the basis of this measured value, it is possible to draw conclusions about the combustion process.
- the ion current measuring device comprises a series circuit comprising a measuring resistor R M and a diode D2, the anode of this diode being connected to the resistor.
- the other terminal of the measuring resistor R M is connected to a measuring voltage U M , while the cathode of the diode D2 is in electrical connection with the second terminal 17 of the secondary winding 9.
- the voltage drop across the measuring resistor R M is fed to a measuring amplifier, preferably an operational amplifier, which generates a difference signal S and feeds it to an evaluation device.
- a measuring amplifier preferably an operational amplifier
- the ignition signal A is set to a voltage level "1" (for example 5 V) at a time t1, with the result that the transistor T2 becomes conductive.
- a primary current I prim thus flows . of the battery voltage U bat via the primary winding 7 and the collector-emitter connection of the transistor 2 to ground. Due to the inductance of the coil 5, the current I prim increases. exponentially.
- This primary current I prim. serves to build up a magnetic field in the coil 5, which is to provide the energy necessary for the ignition.
- the ignition signal A is set to the potential “0” (for example 0 V).
- the transistor T2 falls back into the blocking state with the result that the primary current can no longer flow to ground. As can be clearly seen from the diagram, it falls back to the value 0.
- the control signal B having a "1" level is set to a "0" level at a time t2.
- the control circuit 27 switches the switching element 19 into the conductive state via the control input 25. This creates an electrical connection between the two terminals 11, 13 of the primary winding 7, so that a further reduction of the magnetic energy stored in the coil via the primary current I prim. he follows. In the diagram according to Figure 2 it can be seen that the primary current I prim. has risen significantly at time t2 and slowly decays over time until the stored magnetic energy has dropped to the value 0.
- the secondary current drops I sec. to the value 0.
- a measuring voltage U M is switched on in the ion current measuring device, which generates a current flowing via the measuring resistor R M , the diode D2, the secondary winding 9 and the candle 3.
- the level of this ion current depends in particular on the combustion conditions within the cylinder assigned to the candle 3.
- the current value itself can be determined by tapping the voltage drop occurring at the measuring resistor R M.
- FIG. 3 shows an ignition system consisting of several Ignition coils is built. Such systems are used in multi-cylinder engines, whereby For example, an ignition coil is assigned to each cylinder is.
- the ion current measuring device 31 is in each case with all connections 17 of the secondary windings 9 of the Coil ignition systems 1.1 to 1.3 connected so that structural savings have also been achieved here.
- coil ignition systems can be build up more than those shown in Figure 3 have three individual coils.
- the coils themselves can as single spark or double spark coils be trained.
- the control circuit 27 comprises a transistor T1, the emitter of which is connected to ground.
- the collector of the transistor T1 is connected to the battery voltage U bat via a parallel circuit comprising a resistor R1 and an RC element.
- the RC element consists of a resistor R2 and a capacitor C1, one connection of the capacitor being connected to the collector.
- the control signal to be supplied to the control connection 25 is tapped at a node 29 between the resistor R2 and the capacitor C1.
- control circuit it is possible in the control circuit to provide a transistor for the switching element, the base of which is supplied with a control signal becomes.
- the emitter of the transistor is grounded, while the collector is connected in parallel from a resistor and an RC element to the positive tension.
- the control signal for the switching element is then at the connection node of resistor and capacitor of the RC element tapped.
