Parametric Calculation and Significance of Engine Dynamic Torque in Performance Benchmarking of a Vehicle

Mahindra Research Valley-Praveen Kumar Ramani, Bharathraj Jayaraman, Sangeetha Ramasamy Thiruppathi
Published 2019-10-11 by SAE International in United States
The automotive industries around the world is undergoing massive transformation towards identifying technological capabilities to improve vehicle performance. In this regard, the engine dynamic torque plays a crucial role in defining the transient performance and drivability of a vehicle. Moreover, the dynamic torque is used as a visualization parameter in performance prediction of a vehicle to set the right engineering targets and to assess the engine potential. Hence, an accurate measurement and prediction of the engine dynamic torque is required. However, there are very few methodologies available to measure the engine dynamic torque with reasonable accuracy and minimum efforts. The measurement of engine brake torque using a torque transducer is one of the potential methods. However, it requires a lot of effort and time to instrument the vehicle. It is also possible to back-calculate the engine torque based on fuel injection quantity and other known engine parameters. Though this calculation method is relatively easy, it is not an accurate method. Moreover, it would not be possible to extract engine information of benchmark vehicles. Since every…
