[0002] The engine bench test is a key link in the development of the engine. It is not only an important means to verify the performance and reliability of the engine, but also the basis for ensuring that the engine can operate efficiently and safely. In the test, the engine's operation under different working conditions is simulated to measure and evaluate its performance parameters such as speed, torque, power, fuel consumption, and vibration, so as to ensure that the engine can operate reliably and efficiently when it is delivered to the customer. In the traditional engine bench test, the dynamometer is connected to the engine output end through an elastic coupling to measure performance parameters such as engine speed, torque, and power. Generally, only one dynamometer can be arranged in the whole machine bench test room, and it is impossible to perform whole machine simulation tests on engines with dual power output modes, and it is impossible to evaluate the performance of the engine.
