Definitions

  • the invention relates to a distributorless ignition system for a spark ignition internal combustion engine with an even number of cylinders n.
  • Ignition systems are known (DE-A 39 00 498) which operate without a distributor and in which each spark plug is assigned a separately controllable ignition coil, for example in a four-cylinder internal combustion engine.
  • a distributor-free ignition system with reduced costs is achieved in an even-numbered internal combustion engine by (earlier DE patent application P 41 05 585.3) that half of the cylinders each directly connect an ignition coil the spark plug is arranged, and each of these ignition coils is also connected by a high-voltage cable to a further spark plug which is not directly associated with an ignition coil.
  • the pairing of two cylinders, one of which is connected to the ignition coil / spark plug unit and the other of which is connected to the first via high voltage, is determined so that one has its compression stroke and the other has its exhaust stroke at the same time. When the ignition coil is activated, both cylinders get an ignition spark at the same time.
  • the object of the present invention is to achieve a favorable design which reduces the assembly effort.
  • the ignition coils for the cylinders are combined to form a unit in a housing and that the spark plug connectors for the spark plugs directly associated with the ignition coils are connected to the housing.
  • two ignition coils are operated as one unit;
  • a bleck packet is combined in a housing, in which the spark plug connectors are provided directly, the distance between the spark plug connector is of course matched to the geometrical arrangements of the internal combustion engine, so that two spark plug connectors protrude from the underside of the housing at a distance from the spark plugs of the internal combustion engine, which can be plugged directly onto the spark plugs.
  • the entire connection of the ignition coils to the spark plug connectors has already been established, only the two other spark plug connectors, which are connected to the ignition coils via cables, must be plugged onto the other spark plugs.
  • the usual ignition sequence of a spark-ignited four-cylinder in-line internal combustion engine is according to claim 2 1 - 2 - 4 - 3 or 1 - 3 - 4 - 2, that is cylinders 1 and 4 and cylinders 2 and 3 are each operated at a distance of 360 °
  • the other cylinder has ended the exhaust stroke and will begin the intake stroke.
  • the spark in the other cylinder which is also generated by a parallel connection of the two spark plugs, falls exactly in the end of the exhaust stroke before the start of the intake stroke, so that it without any consequences for the operation of the internal combustion engine.
  • a particularly favorable design is achieved according to claim 3 in that the ignition output stage is also integrated in the housing for the ignition coils.
  • Claims 4, 5 and 6 relate to an arrangement of a cooling plate of the ignition output stage which is favorable for the function and manufacture.
  • Fig. 1 is a perspective view of a spark plug / ignition coil unit
  • Fig. 2 is a perspective view of a cylinder head with an attached spark plug / ignition coil unit with integrated ignition output stage and exposed aluminum cooling plate.
  • the reference numeral 10 denotes a housing which has a laminated core 12 as part of the ignition coils as the base plate.
  • the ignition coils are accommodated in this housing 10, 26 showing a connecting piece for the housing 10 to which the power supply to the ignition coils can be attached.
  • spark plug connectors 14 and 16 protrude downwards, which are assigned to two adjacent spark plugs which are assigned to two cylinders which do not run in synchronism (cylinders 3 and 4, see FIG. 2). can be plugged on.
  • the spark plug connectors 14 and 16 can therefore be assigned to cylinders 1 and 2 or 3 and 4, but not to cylinders 2 and 3, which are operated at a distance of 360 ° crankshaft angle.
  • Two high-voltage cables 18 and 20 are led out of the housing 10, each carrying spark plug connectors 22 and 24 at their ends, which are plugged onto the still free spark plugs.
  • the high-voltage cables can be permanently injected or alternatively connected via plug-in couplings.
  • FIG. 2 shows a cylinder head 30 (the position of the cylinders is shown with the reference numerals 1 to 4) on which the spark plug / ignition coil unit according to FIG. 1 is already mounted.
  • the plug plugs 14 and 16 connected thereto are already plugged onto the associated spark plugs of the cylinders 3 and 4.
  • the spark plug connector 24 is plugged onto the spark plug of the cylinder 1 and thus assigned to the cylinder 4.
  • the spark plug connector 22 is plugged onto the spark plug of the cylinder 2 and thus assigned to the ignition coil for the cylinder 3.
  • An ignition output stage 31 is also integrated here on the housing 10, the aluminum cooling plate 32 of which is exposed on the top of the housing 10 and is not covered by the plastic cover of the housing 10. The exposed aluminum cooling plate 32 is sealed against this plastic cover.

Abstract

Dans un système d'allumage sans distributeur, une bobine d'allumage associée à une moitié des cylindres est connectée par un câble de haute tension à un cylindre correspondant de l'autre moitié des cylindres. Les bobines d'allumage sont assemblées en un module dans un seul boîtier.
