为什么小排量汽车冬天油耗越来越高?

来源:http://www.lutongqixiu.com/ 日期:2019-12-31 发布人:admin
  由于小排量汽车重量轻,意味着只有较少的油耗产生的小牵引力才能克服它的重量带来的阻力,在正常情况下100公里的油耗会很低。但是冬天会如上所述,润滑油脂粘度增加将需要额外的燃料工作克服阻力,隔热还需要额外的燃料消耗,和小排量汽车引擎是体积更小,重量更轻,气缸壁薄,气缸内高温丢失将会相对容易,隔热的燃料消耗将更明显。
  Due to the light weight of small displacement vehicle, it means that only the small traction force generated by less fuel consumption can overcome the resistance brought by its weight. Under normal circumstances, the fuel consumption of 100 km will be very low. But in winter, as mentioned above, the increase of grease viscosity will require additional fuel work to overcome the resistance, and the heat insulation also requires additional fuel consumption. The engine of small displacement vehicle is smaller, lighter, and the cylinder wall is thin. The high temperature loss in the cylinder will be relatively easy, and the heat insulation fuel consumption will be more obvious.
  同时由于平时燃油消耗量较低,冬季即使燃油消耗量增加不到1升,但相对燃油消耗量也可能增加10%以上甚至20%,增幅会显得非常大。冬季石油消费为何“热遥高”?位移越小,越明显?不能伤害!
  At the same time, due to the low fuel consumption at ordinary times, even if the fuel consumption increases by less than 1 liter in winter, the relative fuel consumption may increase by more than 10% or even 20%, with a very large increase. Why is the oil consumption "hot and high" in winter? The smaller the displacement, the more obvious it is? No harm!
  正是由于这个原因,大排量的汽车燃料消耗增加不是很明显,1升油只会增加几个百分点,和大排量的汽车,发动机气缸壁厚比小排量的车,所以热损失会相对较慢,大位移,产生的热量也很高。冬季石油消费为何“热遥高”?位移越小,越明显?不能伤害!
  It is for this reason that the increase of fuel consumption of vehicles with large displacement is not very obvious. One liter of oil will only increase by a few percentage points. For vehicles with large displacement, the wall thickness of engine cylinder is smaller than that of vehicles with small displacement, so the heat loss will be relatively slow, large displacement, and the heat generated will be very high. Why is the oil consumption "hot and high" in winter? The smaller the displacement, the more obvious it is? No harm!
  其实冬季的油耗比夏季略高是有一定原因的,而且不止一个,是由各种综合因素造成的。
  In fact, the fuel consumption in winter is slightly higher than that in summer for some reasons, and there are more than one, which is caused by various comprehensive factors.
  1. 热车好长时间了
  1. It's been a long time since the car was hot我相信很多车主都有一个早上热车的好习惯,但是盲目的等待车速降到正常值或者水温到正常,这等于在和他们的钱包。事实上,我国大部分地区的车主都可以在车辆启动半分钟左右来齿轮传动,然后一个挡后再正常行驶一段距离。而对于一些北方城市来说,冬季太冷的时候可以适当延长热车时间。此外,当水温过低时,发动机会告诉喷油器要喷更多的燃油,所以如果你的通勤时间很短,而且冬天的寒冷天气让水温很难上升到正常,你的车肯定会消耗更多的燃油。冬季石油消费为何“热遥高”?位移越小,越明显?不能伤害!

  I believe that many car owners have a good habit of hot car in the morning, but blindly waiting for the speed to drop to normal or the water temperature to normal, which is equivalent to working with their wallets. In fact, most of the car owners in most areas of our country can start the car for about half a minute to gear, and then drive for a normal distance after a gear. For some northern cities, when it's too cold in winter, the hot car time can be extended appropriately. In addition, when the water temperature is too low, the engine will tell the fuel injector to spray more fuel, so if your commute time is very short, and the cold weather in winter makes it difficult for the water temperature to rise to normal, your car will definitely consume more fuel. Why is the oil consumption "hot and high" in winter? The smaller the displacement, the more obvious it is? No harm!
  2. 热效率较低
  2. Low thermal efficiency
  一般来说,发动机工作时需要保持常温环境,大约80°C~90°C。如果温度过高,发动机的冷却系统会自动增加水循环速度,增加散热,带走多余的热量。否则,冷却水的循环速度就会降低,以保持必要的温度。这是发动机更基本的冷却原理。在冬天,发动机需要保温而不是冷却。由于空气流动的影响,发动机的温度不容易维持在80℃左右,这将增加燃油喷射,改变“点火提前角”来维持温度。与此同时,寒冷天气下汽油的热效率远低于夏季,这使得冬季寒冷天气下的燃油消耗量高于其他季节。冬季石油消费为何“热遥高”?位移越小,越明显?不能伤害!
  Generally speaking, the engine needs to maintain a normal temperature environment, about 80 ° C ~ 90 ° C. If the temperature is too high, the cooling system of the engine will automatically increase the water circulation speed, increase the heat dissipation and take away the excess heat. Otherwise, the circulating speed of the cooling water will be reduced to maintain the necessary temperature. This is the basic cooling principle of the engine. In winter, the engine needs to be insulated rather than cooled. Due to the influence of air flow, the engine temperature is not easy to maintain at about 80 ℃, which will increase fuel injection and change the "ignition advance angle" to maintain the temperature. At the same time, the thermal efficiency of gasoline in cold weather is far lower than that in summer, which makes the fuel consumption in cold weather in winter higher than that in other seasons. Why is the oil consumption "hot and high" in winter? The smaller the displacement, the more obvious it is? No harm!
  电池的效率很低
  The efficiency of the battery is very low冬天的白天变短了,夜晚变长了,车前灯比夏天开得长。另外,由于冬季温度较低,电解液化反应缓慢,容易造成电池损耗。还有就是冬天开始冷,为了克服电阻对电力的更大需求。而发动机的启动需要更多的燃料转换电能来给电池充电,所以相对来说也是燃料消耗的一个因素。冬季石油消费为何“热遥高”?位移越小,越明显?不能伤害!
  The days are shorter in winter, the nights are longer, and the headlights are longer than in summer. In addition, due to the low temperature in winter, the electrolytic liquefaction reaction is slow, which is easy to cause battery loss. There is also the beginning of cold winter, in order to overcome the resistance of the greater demand for electricity. The start-up of the engine requires more fuel to convert electric energy to charge the battery, so it is also a factor of fuel consumption. Why is the oil consumption "hot and high" in winter? The smaller the displacement, the more obvious it is? No harm!
  4. 暖空气也会增加燃料消耗
  4. Warm air will also increase fuel consumption天气寒冷,打开暖空气也会增加汽油的油耗,这比夏天打开空调消耗的汽油多得多。有些司机觉得暖空气是消耗发动机的热量,不会增加油耗。其实,冬季发动机为了保持温度,大多处于小周期;当你打开热空气时,车内的冷空气会迅速流过堆芯表面,本质上是给发动机的冷却循环增加了一个的散热器!你可以想象它的效果。冬季石油消费为何“热遥高”?位移越小,越明显?不能伤害!
  In cold weather, turning on warm air will also increase the fuel consumption of gasoline, which is much more than turning on the air conditioner in summer. Some drivers feel that warm air consumes the heat of the engine and does not increase fuel consumption. In fact, in order to maintain the temperature of the engine in winter, most of the engine is in a small period; when you turn on the hot air, the cold air in the car will quickly flow through the core surface, essentially adding an efficient radiator to the cooling cycle of the engine! You can imagine its effect. Why is the oil consumption "hot and high" in winter? The smaller the displacement, the more obvious it is? No harm!
  5. 长夜短昼很重要
  5. Long night and short day are very important燃油消耗也随着天气的增加而增加,冬季天黑得早,在工作中,一般都需要打开前大灯,前大灯的电力供应是由发动机油燃烧供应的,这也会直接影响爱车的油耗。冬季石油消费为何“热遥高”?位移越小,越明显?不能伤害!
  Fuel consumption also increases with the increase of weather. It is dark early in winter. In work, the headlights generally need to be turned on. The power supply of the headlights is supplied by the engine oil combustion, which will directly affect the fuel consumption of your car. Why is the oil consumption "hot and high" in winter? The smaller the displacement, the more obvious it is? No harm!
  6. 可怜的油流
  6. Poor oil flow
  人在冷热天气中变化,汽车也一样。如果注意不到位,增加的油耗量就小,对机械部件的损坏就大。
  People change in hot and cold weather, so do cars. If the attention is not in place, the increased fuel consumption will be small and the damage to mechanical parts will be large.
  冬天来的时候,我们可以选择低温流动性较好的油,比如5W或0W的油,对于大部分年份都不旧(3-5年),车的状况很好,冬天来的时候,选择低温流动性较好的油就可以了。
  When winter comes, we can choose the oil with better low-temperature fluidity, such as 5W or 0W oil, which is not old for most years (3-5 years), and the car is in good condition. When winter comes, we can choose the oil with better low-temperature fluidity.
