ZUE 282.130 Function Description
The ignition angle (zwgru) from the fundamental ignition angle calculation is corrected by the warm-up angle (dzwwl) and the cylinder-specific knock control angle (dwkrz), and it follows that the basic ignition angle (zwbas) is identical with the earliest possible ignition angle. This ignition angle now forms the route in to the ignition engine torque implementation (MDZW), which provides the output ignition angle (zwsol). This ignition angle is now limited to the earliest or latest possible ignition angle. The resulting ignition angle (zwist) is corrected by the phase error which gives the output ignition angle (zwout).
For back-up protection of the ignition angles, the one’s complement (i.e. inverse binary value) of zwout is calculated which forms zwoutcpl. This then becomes the input variable of the function monitor.
The cylinder bank selective ignition angle adjustment is activated via the codeword CWDZWLL = 1.
The delta ignition angle (dzwll) corresponding to B_bankl2 is added to, or subtracted from zwsol.
ZUE 282.130 Application Notes
Three interfaces are provided for the application; the RAM cell vszw and the fixed value ZWAPPL ZW enable adjustment of application tools. Engagement of the torque functions can be disabled using the codeword CWMDAPP (bit 0), so that the applied ignition angle (zwbas) can be driven directly.
