ABSTRACT:
A system and method for detecting and correcting power imbalance between cylinder banks of an internal combustion engine utilizes, in one embodiment, temperature sensors at the exhaust manifolds for each cylinder bank. A differential temperature value .DELTA. is generated and used to determine which cylinder requires modification of its operating conditions to equalize the power output between the opposing banks. In one embodiment, the sign of the value .DELTA. is used to determine which cylinder bank has the highest exhaust temperature, and the value .DELTA. is provided as a multiplier to engine operating algorithms implemented by the engine control computer to derate the subject cylinder bank. In another embodiment, the value .DELTA. is used to uprate the bank having the lower exhaust temperature, indicative of a lower power output.
