Exhaust Emission Test, Fuel Consumption Test and Others

Exhaust Emission Test in 1015- and 11-Modes

This involves measurement of the weight of CO, HC and NOx contained in exhaust emissions from motor vehicles running in a specified test mode. In addition to CO, HC and NOx, the weight of particulate matter is also measured for diesel-powered motor vehicles.

Exhaust Emission Test in 13-Mode

This involves measurement of the weight of CO, HC and NOx contained in exhaust emissions from heavy-duty motor vehicles such as trucks and buses running in a specified test mode. In addition to CO, HC and NOx, the weight of particulate matter is also measured for diesel-powered motor vehicles.

Two-Wheeled Motor Vehicle Exhaust Emission Test

This involves measurement of the weight of CO, HC and NOx contained in exhaust emissions from two-wheeled motor vehicle running in a specified test mode.

Fuel Evaporative Emission Test

The weight of all HC evaporated from a fuel tank and other devices is measured during soaking the gasoline-fueled motor vehicle for 24 hours in the enclosure with controlled temperature.
