Definitions

  • the invention relates to a contactless ignition system for internal combustion engines, with a plurality of ignition signal transmitters, a downstream evaluation circuit and with ignition coils controlled thereby, to the secondary windings of which a spark plug for different cylinders of the internal combustion engine is connected on both sides.
  • each cylinder of the internal combustion engine is assigned a spark plug.
  • the two spark plugs connected to each other via a secondary winding are driven simultaneously. This is done in such a way that the spark plug of the cylinder, which is currently in the compression stroke and whose spark plug is to be ignited, is connected to the other spark plug, the cylinder of which is currently in the exhaust stroke at low internal pressure and is therefore practically short-circuited. In this way it is possible to get by with a number of ignition coils and ignition signal generators that is halved compared to the number of spark plugs.
  • the invention has for its object to provide an ignition system of the type mentioned, in which the highest level of security against ignition failures in one of the cylinders is achieved with minimal effort.
  • the invention solves this problem in that the number of ignition coils is equal to the number of cylinders, that two spark plugs are assigned to each cylinder, that the spark plugs are connected to different ignition coils, and that the ignition coils are activated in pairs at the same time.
  • Two ignition coils are activated to ignite the mixture in one of the cylinders.
  • the four spark plugs connected to their secondary windings are driven.
  • the two spark plugs arranged in the cylinder of interest are ignited. If such a spark plug fails, the ignition of the remaining spark plug is sufficient.
  • the two other spark plugs can be arranged in one or two cylinders, which are just in the exhaust stroke and thus do not come to ignition.
  • the failure of an evaluation and amplifier circuit connected downstream of the ignition signal transmitters is also harmless, since at least one of the spark plugs is still ignited in each of the cylinders and therefore the mixture contained therein is combusted.
  • the invention offers several advantages over the possible assignment of the two spark plugs of each cylinder to a single ignition coil.
  • the required secondary voltage is at Invention for each ignition coil only a small amount higher than in the case of an ignition coil, which is only connected to a single spark plug.
  • the simultaneous ignition of two spark plugs of a cylinder with an ignition coil means a doubling of the secondary voltage and therefore a significantly higher load on the ignition coil.
  • this possibility offers no protection against the failure of an evaluation circuit or an ignition coil. In such a case, the two spark plugs are not ignited, since the only associated ignition coil is not activated or is not activated correctly or is itself defective.
  • An improvement of the invention deals with the problem of assigning the spark plugs to the ignition coils.
  • it is possible to assign the cylinders as required. This is associated with the risk that, under unfavorable conditions, faulty pre-ignition will occur in one of the cylinders.
  • there is an error-free ignition of the mixture in a paired assignment such that two of the four controlled spark plugs are located in the cylinder that is currently in the exhaust stroke.
  • the additional advantages of this measure can be seen in the relatively low voltage value of the secondary voltage of the two ignition coils.
  • An ignition system for internal combustion engines contains four ignition coils 5 to 8, assuming four cylinders 1, 2, 3 and 4, to whose secondary windings 5 'to 8' two spark plugs 9 and 10, 11 and 12, 13 and 14 as well as 15 and 16 are connected.
  • the ignition coils 5 to 8 are controlled by an evaluation and amplifier circuit 17, not shown in detail, which is controlled by a contactless, known per se and not shown in detail camshaft position transmitter.
  • the spark plugs are assigned to the ignition coils in pairs. This means that the spark plugs 1 and 15, 10 and 16 or 11 and 13, 12 and 14 associated with cylinders 1 and 4 or 2 and 3 are connected to a pair of ignition coils 5 and 8 or 6 and 7.
  • the ignition coils of a pair are controlled simultaneously by the evaluation circuit. If the mixture is to be ignited in one of the cylinders 1, the ignition coils 5 and 8 are activated simultaneously.
  • the spark plugs 9 and 15 simultaneously ignite the mixture of the cylinder 1. Even if one of the spark plugs 9 or 15 or the part of the evaluation circuit 17 which controls the ignition coils 5 or 8 fails, it is not critical since the spark plug still remaining for the ignition 9 or 1 5 the mixture ignites completely.
  • the spark plugs 10 and 16 are activated. However, these do not find any flammable mixture, since the cylinder 4 is in the exhaust stroke and the spark plugs 10 and 16 are therefore practically short in terms of high-voltage technology.
  • the ignition coils 5 and 8 are actuated together again.
  • the spark plugs 10 and 16 now ignite, while the spark plugs 9 and 15 do not find any flammable mixture.
