During that time, the vehicle temperature of the enclosure is managed so that it simulates daytime and nighttime ambient temperatures while sophisticated chemical analyzers measure evaporative emissions to ensure compliance with regulations. As its name suggests, the SHED device is an enclosure where a vehicle is parked for one or two days. NVFEL evaluates evaporative emissions of volatile organic compounds (VOCs) from parked vehicles using an evaporative emissions sealed housing emissions device (SHED). VOCs are pollutants that contribute to the formation of ground level ozone, or smog.

To evaluate exhaust emissions and fuel economy performance in a way that is accurate and repeatable, vehicles are driven on the dynamometer over standard test cycles. This means all the cars are driving the exact same way for our tests.

Sophisticated chemical analyzers measure pollutants from the vehicle exhaust. A dynamometer consists of one or two large rollers connected to an electric motor. The vehicle being tested drives on the rollers, which simulate the speed and resistance of an actual road. Cars and light trucks are tested on a chassis dynamometer, under tightly-controlled conditions that simulate the operation of a vehicle on the road.
