1. suburb conditions 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 actual fuel consumption identified in the body of the vehicle before the vehicle factory, car fuel consumption identity refers to light vehicles were marked urban conditions, working conditions and general conditions outskirts of fuel consumption and other consumption categories logo, another import car fuel consumption is also to be affixed identity, to facilitate consumer recognition level of fuel consumption 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 .
a suburb operation cycle comprising 40 seconds idling; 10 seconds idling, deceleration of the vehicle, the clutch is disengaged; 6 seconds shift; 103 seconds acceleration traveling; constant speed of 209 seconds; 32 seconds slow down. Suburb cycle for a total time of 400 seconds. Because it is on the outskirts conditions, constant speed the longest time, 52.2 percent of total duration. The outskirts of conditions, public car average speed was 62.6, The top speed of 120 km. Theoretical distance of 6.955 kilometers per cycle. Such a test should be repeated three times. Calculate the average fuel consumption.
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.
