Description:

As global emission regulations become more and more stringent, in order to shorten the engine development cycle, the vehicle emissions (RDE, Real Driving Emission) during road driving are closer to the emission level measured by the engine in the test room, which requires engine testing The test boundary conditions in the development stage of the engine room are closer to the actual operating state of the engine when the vehicle is driving on the road, so that the engine emission level developed can more truly reflect its true level, and the post-processing conversion efficiency test in the engine test room comes into being.
