专家对你说10招防止油耗过高(国外英语资料) Experts say 10 strokes to prevent excessive fuel consumption Owner experience A winter to spend money, the owner of Miss Li found that every winter she had to spend more money than usual. For this case, the owners around the same feeling, seems to drive a large fuel consumption in winter. Miss Li wondered: in order to save oil, in the winter she did not dare to open the air-conditioning ah, why not open air-conditioning, fuel consumption will be high? Expert In winter, the heat efficiency of gasoline is not as good as that in summer. Is it faster to drive a car in winter than in other seasons? First of all, we should figure out the working principle of the engine. Generally speaking, need to have normal temperature environment when the engine works (80 DEG C 90). If the temperature is too high, the engine cooling system will automatically increase the water circulation cooling system, increase heat to remove excess heat; the net, car car car sky, to provide you with a happy car life is our aim, you do the owner, I do! Instead, reduce the cooling water circulation, to maintain the necessary temperature. Understanding the basic cooling principle of an engine will make it clear that winter engines need heat preservation rather than heat dissipation. Due to the influence of the flowing air, the temperature of the engine is not easily maintained at about 80 degrees, and the engine will increase the injection quantity and change the ignition advance angle to maintain the temperature. At the same time, the thermal efficiency of gasoline is also much less than the summer cold. These factors naturally contribute to the higher fuel consumption in winter than in other seasons. Oil saving cheats The oil used for blowing hot air in winter is higher than that in summer. Because the winter in order to keep the engine temperature, mostly in small circulation, when you open the air, cold air flowing through the surface of heatercore car, in fact is a radiator
