Chassis Dyno for Commercial Vehicle(Φ72〞Roller) (2x2)

Chassis Dyno for commercial vehicle can be used for the dynamic performance test,economic performance test, and emission test. The system adopts an AC electric dynamometer, which can simulate road resistance with full electrical inertia based on the inherent mechanical inertia of the chassis dynamometer itself, and can reproduce the road driving resistance or customized road resistance of the tested vehicle. The system is in accordance with the technical requirements of national standards and 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 interface with various emission analyzers to achieve national emission standards for automotive pollutants and foreign testing cycle operating routes. It can also be upgraded according to user requirements to meet the testing requirements of other national emission standards.
