Definitions
- the invention relates to an ignition and injection control device for the internal combustion engine of a motor vehicle with an ignition unit and an injection control unit, the are connected to the central machine control.
- Such an ignition and injection control device is known from EP 0 640 762 A1 and serves, on the one hand for the ignition of the fuel mixture in the cylinders of the Internal combustion engine via the spark plugs and arranged there on the other hand for the injection of fuel into the Internal combustion engine at the appropriate times to care.
- the ignition unit and the injection control unit as separate units, each with its own power supply intended.
- the known device Due to the separate arrangement of the ignition unit and the injection control unit each with its own power supply
- the known device has the disadvantage a high susceptibility to failure due to the large number electrical connection points.
- Such device is also the assembly effort on the production line on the part of the motor vehicle manufacturer very large and results from the separate power supplies a considerable cost disadvantage.
- the object underlying the invention is therefore, in the ignition and injection control device of the trained in such a way that they have a low Susceptibility to failure.
- the Ignition unit and the injection control unit including their power supplies through the power supply to one Assembly module summarized what the number of electrical Contacts significantly reduced and thereby a lower Guaranteed failure of the device.
- the ignition and injection control device has the further advantage that the assembly and Cabling expenditure on the production line of the motor vehicle manufacturer less that is due to the training in shape of an assembly module, the logistics effort is lower because no handling of cables and components is required, and that due to the common power supply of the Ignition unit and the injection control unit by the power supply a cost advantage arises.
- the only figure shows the schematic diagram of the Embodiment of the device according to the invention.
- the ignition and injection control device shown in the drawing 9 for the internal combustion engine of a motor vehicle those with spark plugs 7 and injection valves 8 is equipped, comprises an ignition unit 3 and an injection control unit 2, each with the spark plugs 7 and the injection valves 8 are connected and control them.
- the ignition unit 3 usually contains a charging capacitor, a transformer or an ignition coil, semiconductor power switch etc. as well as a spark plug connector to the spark plugs 7 and possibly an evaluation circuit for ignition diagnosis and misfire detection.
- a charging capacitor for charging the charging capacitor are at based on today's shunt-proof ignition concepts of HKZ or AC voltage ignitions compared to the vehicle electrical system voltage increased voltages of 60 to 500 V are required.
- the injection control unit 2 also requires control of the injection valves 8 with piezo capacitors increased charging voltage of 60 compared to the vehicle electrical system voltage up to 500 V.
- the power section of the injection control unit 2 is directly via a plug connection with the injection valves 8 connected.
- the ignition unit 3 and the injection control unit 2 are via a central plug 4 with the central machine control ECU 6 connected for machine management worries.
- the mentioned increased DC voltages from 60 to 500 V for the ignition unit 3 and the injection control unit 2 are supplied by a single power supply 1, which via the central plug 4 is connected to the electrical system 5, the is essentially called the battery voltage of the motor vehicle lies.
- the ignition and in the form of an assembly module Injection control device 9 with a single power supply 1, that the supply voltages for the ignition unit 3 and Injection control unit 2 delivers, is in particular designed that they can be contacted directly on the machine built-in spark plugs 7 and the injection valves 8 can be plugged on without additional wiring necessary is. If you have problems with the available space in the engine room, however, it may be necessary be the power supply 1 from the rest of the mounting module 9 separate.
