MC2000 car chassis dynamometer is a system to test the performance and emission for the lightweight car. Adopting AC dynamometer as the main engine, the chassis dynamometer system meets the needs of the performance test for lightweight cars (The maximum design speed is 200km/h.), which are powered by the spark ignition engine or compression ignition engine. The system can be connected with various kinds of exhaust sampling and analysis system to satisfy the requirements of lightweight car emission standards and cycle duties in foreign countries. What’s more, this system can be upgraded according to users’ needs to meet the requirements of emission standard test in other countries.
