Method for assigning addresses to injectors
A method for assigning addresses to injectors of an internal combustion machine, wherein, prior to the starting procedure, an electronic motor control device selects a first injector by activating the first injector by a first control line from the electronic motor control device. The electronic motor control device is arranged on a data bus to which the electronic motor control device and all injectors are connected. A first address value is placed on the motor control device and the first injector assumes the first address value as the address assigned to it.
1. A method for assigning addresses to injectors of an internal combustion engine, comprising the steps of: prior to a starting procedure, selecting a first injector and activating the first injector through a first control line by an electronic motor control device so that in practical motor operation the first injector is activated via the first control line to inject fuel; and placing a first address value on a data bus to which the electronic motor control device and all injectors are connected, the electronic motor control placing the address value on the data bus, the first injector assuming the first address value as the address assigned to it.
2. The method according to claim 1 , wherein the first injector acknowledges receipt of the first address value by placing an acknowledgement value on the data bus.
3. The method according to claim 2 , wherein the electronic motor control device concludes the address assignment after receiving the acknowledgement.
4. The method according to claim 3 , wherein the electronic motor control device selects a second injector through a second control line and the second injector is activated by the electronic motor control device via a second control line so that in practical motor operation the second injector is activated via the second control line to inject fuel, the electronic motor control device places a second address value on the data bus, and the second injector assumes the second address value as the address assigned to it.
5. The method according to claim 1 , wherein the address value is composed of a value characterizing a cylinder bank and a running number for the injectors of the cylinder bank.
6. The method according to claim 1 , wherein the method concludes after all injectors have been assigned an individual address by the electronic motor control device.
7. The method according to claim 6 , wherein the electronic motor control device and the injection system are ready for start with conclusion of the method.
8. A device for assigning addresses to injectors of an internal combustion engine, comprising: a data bus; an electronic motor control device as a master; injectors as slaves, the motor control device and the injectors being jointly connected to the data bus; a separate control line connecting each injector to the motor control device over which each injector, during address assignment before a start operation as well during practical motor operation for injecting fuel, is activated or deactivated by the electronic control device; and an electronic component arranged at each injector, wherein the electronic component includes a processor as a computation unit and a data storage.
9. The device according to claim 8 , and further comprising an energy storage arranged at each injector for storing electrical energy, wherein the energy storage temporarily supplies the electronic component with energy.
10. The device according to claim 9 , and further comprising a voltage supply, the injectors being jointly connected to a line connected to the voltage supply.
