What are the functions of the components of the electrical dynamometer in diesel engine tests?

An electrical dynamometer in diesel engine tests primarily measures torque and power output. The key components include a load cell, which converts mechanical force into an electrical signal, and a control system that regulates the load applied to the engine. The data acquisition system captures the engine's performance metrics, while the electrical resistance provides a means to dissipate energy generated during testing. Together, these components enable precise evaluation of engine efficiency and performance characteristics.
