Abstract

A master/slave arrangement of an electronic engine control device with an engine identification module. The electronic engine control device controls and regulates the internal combustion machine. The engine identification module includes at least one microprocessor and a memory building block for storing an engine identification as well as engine specifics. The electronic engine control device and the engine identification module exchange data through an engine cable harness. The engine identification module is arranged inseparably at the crank housing of the internal combustion machine. The engine identification module can be removed from the crank housing as well as from the engine cable harness only by being destroyed.

Claims

1. A master/slave arrangement, comprising:

an electronic engine control device; and

an engine identification module, wherein the electronic engine control device controls and regulates an internal combustion machine, wherein the engine identification module contains at least one microprocessor and a memory building block for storing an engine identification and engine specifics, and wherein the electronic engine control device and the engine identification module exchange data through an engine cable harness, the engine identification module being arranged inseparably on a crank housing of the internal combustion machine so that the engine identification module is separable from the crank housing and from the engine cable harness only by being destroyed.

2. The master/slave arrangement according to claim 1, wherein the engine identification module includes a safety device for encoding data transmission through the engine cable harness from/to the engine control device.

3. The master/slave arrangement according to claim 2, wherein the engine identification module and the crank housing are in engagement with each other through a dovetail connection.

4. The master/slave arrangement according to claim 2, wherein the engine identification module is connected to the crank housing through a locking connection.

5. The master/slave arrangement according to claim 1, further comprising a memory building block in which engine characteristic data is additionally stored which is relevant with respect to exhaust gas laws.

6. A method for controlling and regulating an internal combustion machine with a master/slave arrangement according to claim 1, comprising the steps of:

during an initializing phase, reading the engine identification from the engine identification module with the electronic engine control device; and

permitting normal operation in case of a positive concordance, and locking the starting procedure in case of a negative concordance.

7. The method according to claim 6, including, after an exchange of the electronic engine control device or after an exchange of the internal combustion machine, during the initializing phase, reading the engine identification from the engine identification module with the electronic engine control device, wherein, in the case of a positive concordance normal operation is permitted, and in the case of a negative concordance the starting procedure is locked.

8. The method according to claim 6, including determining engine specifics during a first run of the internal combustion machine on a test bench, storing the engine specifics in the engine identification module during a line end alignment, reading the engine specifics in the initializing phase by the electronic engine control device, and correcting adjusting values of the electronic engine control device based on the engine specifics.

9. The method according to claim 6, including, during the operation of the internal combustion machine, actualizing the operating data in the engine identification module using the electronic engine control device.

10. Method according to claim 9, including storing the data of the electronic engine control device redundantly in the engine identification module.
