Validation of MAIHAK Torque Power Meter

System Overview

The following methods for the main engine power determination with Maihak Torque Validation show the possibilities of self-validation.

  • An offset algorithm informs the user if the engine-specific limit for the torque offset is exceeded during standstill. In this case, a calibration of the system is essential.
  • The dashed line shown in the figure indicates this limit for a short-term permitted offset at standstill. If this behavior remains undetected, it can lead to a mismatch of several percent.
  • In the dynamic case, the frequencies of the negative-correlating vibrating sides are monitored. If this behavior changes, the user receives a message for implausible operation.
