Example Embodiment
[0015] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments, which do not depart from the scope of the present invention, and the description and accompanying drawings are essentially for illustrative purposes, not for use To limit the invention.
[0016] The invention uses the vehicle chassis dynamometer to provide accurate road load simulation and road test conditions for the test vehicle, so that the engine exhaust brake performance test can be performed indoors. Carrying out the vehicle exhaust brake performance test in the Roadload Simulation mode can effectively test the engine exhaust brake performance, especially the use of a chassis dynamometer to simulate downhill roads, which can accurately control the slope and achieve Accurate testing of exhaust brakes for testing vehicle engines....
