1. The urban cycle fuel consumption
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 outside the Ministry of Industry website publicity, car prices must be attached to the vehicle in front of the factory on the vehicle body to identify the actual fuel consumption, vehicle fuel consumption identity refers to light vehicles were marked urban conditions, working conditions and general conditions outskirts of fuel consumption and other categories fuel consumption and identity, in addition to import new car stickers also identify fuel consumption, fuel consumption in order to facilitate the consumers to identify the extent or energy savings.
Test Method fuel 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 total mass of the vehicle does not exceed 3.5 tons) light vehicle, the vehicle will be placed on the bench, the simulated vehicle speed and the load of the vehicle is actually traveling on a road, according to certain work condition (such as idle speed, acceleration, constant speed, deceleration and other conditions) operation, the measurement of carbon dioxide emissions, carbon monoxide and hydrocarbons, oil consumption measurement method according to the carbon balance.
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 .
comprises a urban operation cycle of 60 seconds idle; 9 seconds idling, deceleration of the vehicle, the clutch is disengaged; shift of 8 seconds; 36 seconds with an acceleration; constant speed for 57 seconds; 25 seconds the slow down. Urban cycle for a total time of 195 seconds. Because it is urban cycle, constant speed the longest time, 35.4 percent of total duration. Urban cycle for continuous four times. Urban conditions, flat carAverage speed of 19 km from each cycle theory is 1.013 kilometers. The total distance for the four cycles of 4.052 kilometers.
Since the actual state of the road, too many uncertain factors, the resulting data is for reference only, under normal circumstances, the real fuel consumption than the test value is high.
