汽车省油是大家的共同愿望,已有很多成功的经验,笔者将自己在汽车使用中的一些做法与同行们交流。1.行车时,冷却液的温度一定要控制在80～90℃之间。发动机温度过高或过低,都将直接影响燃料的消耗。实践证明,发动机温度在80～90℃时为最好,如果温度过低,经常在40～50℃之间,燃油消耗就要增加10%左右;温度过高会加剧发动机零部件的磨损,同时易产生爆燃,既浪费燃料又降低了功率。 Car fuel economy is the common aspiration of everyone, has a lot of successful experience, the author will own some of the practices in the car to communicate with their colleagues. 1. When driving, the coolant temperature must be controlled between 80 ~ 90 ℃. Engine temperature is too high or too low, will have a direct impact on fuel consumption. Practice has proved that the engine temperature at 80 ~ 90 ℃ is the best, if the temperature is too low, often between 40 ~ 50 ℃, fuel consumption will have to increase about 10%; overheating will exacerbate the wear and tear of engine parts, at the same time Deflagration is easy to produce, which not only reduces the fuel but also reduces the power.
