Overview
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.
This equipment is used to simulate the road driving resistance of 4WD and 2WD vehicles of M1, M2 and N1 categories with a maximum gross vehicle mass not exceeding 4500kg.
