Definitions

  • the invention relates to air-compressing internal combustion engines according to the preamble of claim 1.
  • an air-compressing internal combustion engine in which the fuel is injected via an injection nozzle into the combustion chamber arranged in the piston.
  • an ignition device consisting of a spark plug with a sleeve at least surrounding the electrodes of the spark plug is provided, openings being machined into the outer surface of the sleeve.
  • This design has the disadvantage that, despite the partial shielding formed by the sleeve, the ignition space on the spark plug cools down so much due to the entering fuel that, particularly when the internal combustion engine is operating with fuels that do not ignite, the ignition source must be kept in operation so that one evaporates or igniting the incident fuel jets sufficient amount of heat is given off.
  • the continuous supply of electrical energy - reduction in the useful power that can be delivered by the internal combustion engine - leads to a correspondingly high electrode erosion, which reduces the service life of the spark plug.
  • the invention is based on the object of providing an ignition device for air-compressing internal combustion engines, by means of which reliable ignition of the fuel, preferably unwilling to be ignited, injected into the combustion chamber of the internal combustion engine is ensured in the entire operating range, the wear of the ignition device and the electrical energy to be supplied to the ignition device being minimized should be.
  • a pin protruding into the sleeve is attached to an internal bead of the sleeve on the combustion chamber, on which a filament is wound, which is supported on the inner bead of the sleeve and on the ground electrodes of the spark plug designed as a high-voltage spark plug, the area the sleeve, which extends from the internal bead on the combustion chamber to the area of the ground electrodes, extends completely into the combustion chamber. It has surprisingly been found that the electrical operating or ignition power to be supplied to the ignition device can be considerably reduced by the configuration according to the invention.
  • the ignition system which is preferably designed as a high-voltage buzzer
  • the spark spark quickly heats up due to the continuous spark.
  • the fuel-air mixture which has penetrated into the ignition chamber is ignited and in turn heats the filament arranged in the ignition chamber and the pin which at least partially projects coaxially into the filament. Due to the interaction according to the invention of the heat accumulators, incandescent filament and pin, the high-voltage spark plug only needs to be switched on during start-up, warm-up and after the internal combustion engine has been pushed.
  • a high-voltage spark plug 2 which forms the ignition device, is screwed into a schematically indicated cylinder head 1.
  • the high-voltage spark plug 2 is screwed into the cylinder head 1 so far that the electrodes 3, 4 just protrude into the combustion chamber 5 of the internal combustion engine.
  • the electrodes 4 represent the ground electrodes, while the electrode 3 is the high voltage or ground electrode.
  • a sleeve 6 is also attached, for example by a screw.
  • the sleeve 6 protrudes into the combustion chamber 5 and is provided at its combustion chamber end with an inner bead 7 to which a pin 8 is fastened coaxially to the sleeve 6.
  • the pin 8 protrudes into the interior of the sleeve 6 and ends at a defined distance in front of the high-voltage electrode 3.
  • the ignition chamber 9 formed by the sleeve 6 and the pin 8 is through bores 10 which are on the outer circumference of the sleeve 6 in the region close to the cylinder head are attached to the combustion chamber 5 of the internal combustion engine.
  • a filament 11 is wound around the pin 8, which is supported on the inner bead 7 and on the ground electrodes 3 of the high-voltage spark plug 2.
  • the filament 11 is advantageously wound from 0.5 to 1 mm thick scaling-resistant wire.
  • the pin 8 is advantageously designed as a hollow pin closed on one side, the closed side representing the end of the pin 8 facing the high-voltage electrode 3.
  • the high-voltage spark plug 2 is advantageously switched on and off by means of a signal transmitter which is coupled to the control rod of the fuel delivery pump and emits a signal to a control device as soon as the control rod is in the state of delivery. Furthermore, the exhaust gas temperature of the internal combustion engine is measured by the control device via a measuring sensor. The two measured parameters are processed in the control device in such a way that when the exhaust gas temperature falls below a predeterminable temperature and the control rod is simultaneously set in the operating range “delivery”, electrical energy is delivered to the high-voltage ignition device.
  • the spark plug only functions for a short time and with relatively cold electrodes 3, 4, so that in addition to lower energy consumption, the electrode erosion of the high-voltage spark plug 2 is minimized and the service life of the high-voltage spark plug 2 is correspondingly long.
  • the high-voltage spark plug 2 is advantageously of a Schofre quent buzzer ignition fed, each high-voltage spark plug 2 is provided with an ignition coil integrated in the plug connector, which can be connected in parallel on the low-voltage side - corresponding to the number of high-voltage spark plugs 2 used in an internal combustion engine - and spark simultaneously without an ignition distributor.
