Test method and test system of resistance moment power of engine

The invention provides a test method and a test system for resistance moment power of an engine. The method comprises the following steps: setting temperature of a test environment to be constant, fixing a test vehicle on a rotation hub, performing a transmission motored temperature rise test, acquiring a wheel edge force F2 of the rotating hub in the transmission motored temperature rise test; performing an engine motored temperature rise test, and acquiring a wheel edge force F1 of the rotating hub, vehicle speed V and engine oil temperature T of the engine in the engine motored temperaturerise test; according to the wheel edge force F2 of the rotating hub in the transmission motored temperature rise test, the wheel edge force F1 of the rotating hub and the vehicle speed V, calculatingout the resistance moment power P of the engine. With the method and the system provided by the invention, accuracy and integrity of an engine performance test are improved. 本发明提供种发动机阻力矩功率的测试方法及系统，该方法包括：设置测试环境的温度为恒定，将试验车辆固定在转毂
