72 inch heavy chassis dynamometer (1X2)

A heavy-duty chassis dynamometer is a chassis dynamometer that can be used for commercial vehicle power performance testing, economic performance testing, and emission testing. The system adopts an AC electric dynamometer, which can simulate road resistance with full electrical inertia on the basis of the inherent mechanical inertia of the chassis dynamometer. It can also reproduce the road driving resistance of the tested vehicle or customize road resistance. The system is in accordance with national standards and the technical requirements of European and American certification regulations, A completely independent design and development of a brand new automotive testing system with independent intellectual property rights. The system can be integrated with various emission analyzers to achieve national emission standards for automotive pollutants and foreign testing cycle routes. It can also be upgraded according to user requirements to meet the testing requirements of other national emission standards.
