The CDM-300 Series Automotive Chassis Dynamometer is designed in accordance with the requirements of the two-idle speed test method, steady-state test method, and simple transient test method specified in GB18285-2018 "Limits and Measurement Methods for Exhaust Pollutants of Gasoline Vehicles (Two-Idle Speed and Simple Load Mode)", and meets the technical requirements for dynamometers specified in GB3847-2018 "Limits and Measurement Methods for Exhaust Pollutants of Diesel Vehicles". It is suitable for simple load mode (steady-state and simple transient) tests on in-use gasoline vehicles with a maximum total mass not exceeding 3500kg and a maximum design speed of no less than 100km/h, and satisfies the loaded deceleration mode inspection for diesel vehicles with a maximum total mass not exceeding 3500kg.

The DYNO48 Series 48-inch 4WD chassis dynamometer is used to conduct regulatory certification tests, production conformity tests, performance tests, and R&D tests on light-duty vehicles (including various new energy vehicles) with a maximum gross vehicle mass of 500kg-4500kg, in accordance with the requirements of China GB, European ECE and US EPA series regulations and standards, and based on road load spectra or user-defined cycle condition curves.
