Definitions

  • the present invention relates to a static diagnostic device for an ignition device, in particular in a motor vehicle, essentially consisting of an ignition distributor which comprises a sensor whose signals are amplified by an electronic module to control the state of a voltage raising coil.
  • an ignition distributor which comprises a sensor whose signals are amplified by an electronic module to control the state of a voltage raising coil.
  • US-A-4,186,337 describes a test device for an ignition device comprising a coil with an ignition output, an electronic ignition module (connected to said coil, for controlling said ignition output) and an electrical sensor, a device which visually signals the good or bad condition of the various components of the ignition device.
  • the object of the present invention is to remedy these drawbacks and to this end relates to a static diagnostic apparatus for an ignition device of a motor vehicle of the type essentially consisting of an ignition sensor, of a voltage raising coil, of '' an ignition distributor and an electronic ignition module, device capable of defining and signaling faults such as cutting of electrically conductive wire in the electrical network of the ignition device and characterized in that it comprises means capable of ensuring its insertion, without modifying it, into the existing electrical network of the ignition device and visual means for signaling good or bad condition of the various components of the ignition device.
  • the ignition device shown in Figure 1 consists of a sensor 3 whose signals are amplified by an electronic module 2 to control the state of a voltage booster 4 whose secondary voltage is then sent to spark plugs 9 via a distributor 5.
  • the module 2 comprises a connector 8 complementary to a connector 7 which corresponds to the harness 6 of the vehicle ignition device (FIG. 2).
  • control device 1 comprises on the one hand a connector 30 equivalent to the connector 7 and therefore complementary to the connector 8 and on the other hand a connector 20 equivalent to the connector 8 and complementary to the connector 7, so as to allow, without modifying the location of the various constituent elements of the ignition and without locating the electrical wires of the network, the insertion of the diagnostic device (1) into the ignition network as shown in FIG. 2 , and thus to avoid any risk of connection error.
  • Such a diagnostic device essentially comprises the two connectors 20 and 30, two rockers 10 and 100, a voltage reducer 40, a comparator 50, a signal generator 70, two display systems 60 and 80.
  • the connector 20 connects the device 1 to the sensor 3 by connections 21 and 22, to the power supply 12v by connections 23 and 24 and to the coil 4 by connections 24, 25.
  • the connector 30 connects the device 1 to the input of the module 2 by connections 31 and 32, to its output by connections 34 and 35 and to the 12v supply by connections 33 and 34.
  • the sensor 3 is in good condition as well as the electrical connection concerning it, on the other hand if the light 81 is on, the sensor 3 is cut, while if the light 82 stays on this means that sensor 3 is short-circuited, it is therefore necessary to make the appropriate modifications before continuing the tests.
  • the connector 30 can be connected to the module 2 via its connector 8, the inverter 101 of the rocker 100 is placed in position 101a, the test is launched by pressing a few seconds on a push button 11 of the rocker assembly 10, which supplies a relay 12 which controls the switches 13 to 15 which come in positions 13b, 14b and 15b. During this launch, the signaling system 80 flashes and the red lamp 62 is on. The push button 11 is then released and if the red lamp 62 goes out and the green lamp 61 lights up the battery and the sensor, the module and the primary coil are in good condition, the fault sought is therefore at the level secondary coil or HT bundle spark plugs.
  • the inverter 101 is then tilted to its position 101b, the device is restarted as before by the push button 10 which is then released, if the red lamp 62 remains on, the module 2 is faulty, it must therefore be replaced. On the other hand, if the red lamp 62 goes out and the green lamp 61 comes on, the battery, the sensor and the module are in good condition. It will be deduced therefrom that the primary coil or the connection of the coil to the module are faulty, because only these have not yet been tested, so repair must be carried out.
  • Such an apparatus has the essential advantage of being simple to use and of enabling location by stage of any possible defect in an ignition device.
