Definitions

  • the invention relates to a contactless ignition system according to the preamble of claim 1.
  • 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 and the failure of an ignition coil is detected in the event of a fault.
  • 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, as in the known ignition system, have one spark plug arranged in one or two cylinders, which are currently in the exhaust stroke and thus 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 combustion of the mixture therein is made possible. Such a failure can be detected and signaled using the voltage monitoring for the primary circuits of the ignition coils.
  • 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 in the invention for each ignition coil is only a small amount higher than for an ignition coil, which is only followed by 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 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 one remaining for the ignition Spark plug 9 or 15 completely ignites the mixture.
  • 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. Now the spark plugs 10 and 16 ignite, while the spark plugs 9 and 15 do not find any flammable mixture.
