Ministry (government department responsible for investigating some product information) regulations, from January 1, 2010, will establish a system of notification light vehicle fuel consumption, in addition to the Ministry of Industry website publicity, car prices must be before the vehicle is shipped paste actual fuel consumption to identify the car body, car fuel consumption identity refers to light vehicles were marked urban conditions, working conditions and general conditions outskirts of fuel consumption and other categories to identify additional import car fuel consumption is also to be affixed identity, to facilitate consumer recognition level of fuel consumption or energy savings.
1. The Ministry of Industry and combined consumption (L / 100km) Glossary
Ministry (government department responsible for some of the product survey information) regulations, from January 1, 2010, will build light car fuel consumption publicity system, in addition to the Ministry of Industry website publicity, car prices must be attached to the actual fuel consumption identified in the body of the vehicle before the vehicle factory, car fuel consumption identity refers to light vehicles will respectively be marked urban conditions, suburban working conditions and comprehensive the fuel consumption and other conditions to identify three types of fuel, in addition to import new cars also posted fuel consumption identity, to facilitate consumer recognition level of fuel consumption or energy savings.

Test Method 2 consumption
Test fuel variety of ways, it should be summed up in two: a direct measurement, an indirect measurement. Ministry used the indirect measurements, for (maximum vehicle total mass of not more than 3.5 tons) light vehicle, the vehicle is placed on the lab bench, the vehicle speed and the load simulation of the vehicle on the road actually traveled, in accordance with certain conditions ( the idle, acceleration, constant speed, deceleration and other conditions) operation, the measurement of carbon dioxide emissions, carbon monoxide and hydrocarbons, carbon balance method in accordance with the measured fuel consumption.
Ministry of Industry and fuel consumption test using the European cycle driving law enacted in 2000, we all know that the Ministry of fuel contained urban cycle and suburban conditions in the European cycle driving method, identified 30 percentage urban, suburban 70 percentage . A complete test cycle a total of 1180 seconds, by four urban cycle and a small circulation suburban conditions, where urban cycle were 780 seconds, the maximum speed 50KM / H; suburban conditions 400 seconds, the maximum speed 120KM / H .
In the experiment, to each car during idling, deceleration, shift, acceleration, constant run state and the like. Urban conditions, with an average speed of only 19 km, and idle running for a long time. Suburb conditions, an average speed of over 60 km, and constant speed for a long time. After the combined fuel consumption is the total emissions in urban and suburban two cycles, divided by the total mileage completed two cycles, the use of emissions corresponding to the calculated fuel consumption value.
Since the actual state of the road, too many uncertain factors, the resulting dataFor reference only, under normal circumstances, the real fuel consumption than the test value is high.
