Definitions

  • the invention relates to a method and a device for optimizing the combustion of a fuel-air mixture, in particular for use in internal combustion engines.
  • an ignition system is known, for example, from US Pat. No. 4,522,185, in which high-frequency relaxation pulses form in an electrode interspace, with a current source, an ignition coil and electronic switches connected to the primary winding of the ignition coil Pulse generator, the output of which is connected to the electronic switch, and at least one spark plug are provided.
  • the disadvantage of the known solutions is, in particular, that it does not sufficiently combust the fuels so that there is no inherently desired reduction in the pollutants in the combustion exhaust gases, in particular there is no reduction in the toxicity of the combustion products, since the changes in the fuel / air / mixture parameters during the combustion process are not sufficiently taken into account in the formation of the high-frequency pulses.
  • the object of the invention is to provide a solution with which the combustion and process optimization of the combustion process, ie a higher effectiveness and Completeness of fuel combustion and thus avoidance of toxic combustion products is achieved.
  • this object is achieved according to the invention in that the ignition is effected by high-frequency voltage pulses on electrodes which are connected to the secondary winding, the combustion of the air-fuel mixture taking place the frequency of the voltage pulses is varied as a function of the current strength in the secondary winding of the ignition coil.
  • the invention actively intervenes in combustion by also emitting ignition pulses when the combustion has already been ignited for the first time.
  • the object is achieved in that the ignition system has a power source, an ignition coil, an electronic switch which is connected to the primary winding of the ignition coil, a pulse generator, the output of which is connected to the electronic switch and contains at least one spark plug , characterized in that a feedback signal shaper is provided, the input of which is connected to the output of the ignition coil at the electronic switch and the output of which is connected to the second output of the pulse generator.
  • the ignition system contains the current source 1, an ignition coil 2, an electronic switch 3, which is connected to the primary winding of the ignition coil 2, a pulse generator 4, the output of which is connected to the electronic switch 3, an ignition torque former 5, which is connected to the is connected to the first input of the pulse generator 4 and a feedback signal shaper 6 and a spark plug 7.
  • the feedback signal shaper 6 has its input connected to the ignition coil 2 at the electronic switch 3 connected and its output in turn to the second input of the pulse generator 4.
  • the spark plug 7 is connected to the secondary winding of the ignition coil 2.
  • the above-mentioned signal shaper 5 can be designed, for example, in the form of a resistor and capacitor connected in series.
  • the ignition device described above works as follows:
  • the ignition torque shaper 5 sets the pulse generator 4 in operation synchronously with the engine speed (the engine is not shown in the drawing), for a period of time which is inversely proportional to the engine speed.
  • the pulse generator 4 forms pulses which activate the electrical switch 3, which couples the electrical current in the primary winding of the ignition coil 2 with the pulse sequence frequency. High-frequency pulses are thus generated in the secondary winding of the ignition coil, which lead to electrical discharge between the electrodes of the spark plug 7.
  • the frequency parameters of the secondary circuit of the ignition coil change, which in turn causes a change in current in the secondary and primary winding of the Ignition coil triggers.
  • the strength of the current which arises from the change in the parameters of the fuel in the vicinity of the spark plug electrodes, is converted into a control signal after the feedback signal former 6, which corrects the frequency of the pulses generated by the pulse generator, and consequently also the frequency the electronic discharge on the spark plug 7.
