GENERAL MOTORS ENVIRONMENTAL CHAMBER FOR VEHICLE EMISSION TESTING
General Motors has built an environmental chamber at its Milford Proving Ground to run emission tests at controlled atmospheric conditions. This chamber was designed using constant speed fans and dampers to simulate altitudes between sea level and Denver, which is approximately 5000 ft above sea level. The chamber can also control temperatures within a range of 45-100 deg F at humidities of 9-100 gr H2O/lb dry air. Within this chamber, environmental conditions can be changed to desired levels very quickly to measure the vehicle sensitivity to the change. It is also possible to hold the environment constant and run controlled comparison studies on emission-related components.
