Abstract

See full text

Determining performance of an internal combustion engine coupled to a pump of a torque converter may include determining a rotational speed of the pump, determining a rotational speed of a turbine fluidly coupled to the pump, determining an engine output torque value, corresponding to torque applied by the engine to the pump of the torque converter, as a function of the rotational speed of the pump and the rotational speed of the turbine, and storing the engine output torque value in a memory unit. Alternatively or additionally, engine horsepower may be determined as a function of the engine torque and/or a fuel efficiency of the engine may be determined as a function of the horsepower and fueling rate of the engine. The engine output torque value, horsepower value and/or fuel efficiency may be stored in a memory unit and/or displayed on a display unit.
