With the development of the economy and the increasing living standards of the people, cars have become an integral part of people's lives. Due to the rapid increase in the number of cars, traffic accidents have become a topic of concern for everyone, which puts strict requirements on the safety of cars. At the same time, due to the atmospheric pollution caused by car exhaust emissions, various natural disasters occur from time to time, and human health is seriously threatened. Therefore, strict restrictions have been imposed on the emission of car exhaust in various countries. In order to meet the requirements of safety, environmental protection, and energy conservation, car manufacturers must conduct various performance index tests in product development. The automotive environment simulation laboratory provides an environment for automotive manufacturers to conduct this performance test.
