Many car owners think that the fuel consumption of air conditioning is higher in summer, which is understandable. In winter, your fuel consumption is also so high. What's the matter? Why is the fuel consumption so high in winter? Especially for small displacement cars, where is the fuel consumption? Now let's ask Jinan Audi to help you answer!

为什么小排量的车油耗高更加明显？

Why is the high fuel consumption of small displacement cars more obvious?

因为小排量车自重轻意味着只需要较少的燃料消耗产生的不大牵引力即可克服其自重带来的阻力,在平时百油耗会很低。但是冬季会如前所述,润滑油和润滑脂黏度增加会需要额外的燃料作功来克服阻力,升温保温也会需要消耗额外的燃料,并且小排量车发动机比较轻巧,缸体缸壁较薄,汽缸内的高温向外散失会相对容易,升温保温消耗的燃料会更加明显。

 

The low displacement means that the self weight of the vehicle can be overcome with less fuel consumption. However, in winter, as mentioned earlier, the viscosity of lubricating oil and grease will increase, which will require additional fuel work to overcome the resistance, and the heating and insulation will also consume additional fuel. Moreover, the engine of small displacement vehicle is lighter, the cylinder wall is thinner, the high temperature in the cylinder will be relatively easy to dissipate, and the fuel consumption for heating and insulation will be more obvious.

同时由于平时油耗低,冬季即使油耗只增加不到1升，但是相对油耗也可能增加了百分之十几甚二十,增幅会显得很大。

At the same time, due to the low fuel consumption at ordinary times, even if the fuel consumption only increases by less than 1 liter in winter, the relative fuel consumption may increase by more than 10% or even 20%, and the increase will be very large.

也正是由于这种原因，大排量的汽车油耗增加反而没那么明显了，1升油仅会增加百分之几，而且大排量的汽车，发动机的缸壁相对于小排量的车更厚一点，所以热损失也会相对慢一些，排量大，产生热量也高。

It is also for this reason that the increase in fuel consumption of large displacement vehicles is not so obvious. One liter of fuel will only increase by a few percent. Moreover, for large displacement vehicles, the cylinder wall of the engine is thicker than that of small displacement vehicles, so the heat loss will be relatively slow, with large displacement and high heat generation.

如何应对冬季油耗高？

How to deal with high fuel consumption in winter?

1、注意轮胎气压和磨损

1. Pay attention to tire pressure and wear

由于冬季气温低，轮胎内的气压会出现明显下降，并且轮胎胶质变硬，使轮胎的附着力变差，轮胎附着力的降低会导致车辆动力传递效率变低，油耗增加也就在所难免。

Due to the low temperature in winter, the air pressure in the tire will decrease obviously, and the rubber of the tire will harden, which will make the adhesion of the tire worse. The reduction of the adhesion of the tire will lead to the low power transmission efficiency of the vehicle, and the increase of fuel consumption is inevitable.

2、不要长时间高速行驶

2. Don't drive at high speed for a long time

任何一款车都有经济时速，高速行驶会增加空气阻力，从而增加油耗。此外，也要避免频繁的急加速和急刹车，保持匀速行驶。

Any car has economic speed, high speed will increase air resistance, thus increasing fuel consumption. In addition, it is necessary to avoid frequent rapid acceleration and braking and keep driving at a constant speed.

3、平时要加强对车的保养

3. We should strengthen the maintenance of the car at ordinary times

车轮轴承应按时上油，可减少摩擦力，从而降低油耗，还有机油黏度，也会导致油耗增加。

The wheel bearing should be oiled on time, which can reduce the friction and thus reduce the fuel consumption. The viscosity of the oil will also increase the fuel consumption.

4、上述三点其实都是外部因素，内部因素还是自己的驾驶习惯，比如不急加速、不急刹车、缓慢起步，这些都是省油的一些小技巧，想省油更关键的还是要看自己。

4. In fact, the above three points are all external factors. The internal factors are your own driving habits, such as slow acceleration, slow braking and slow starting. These are some tips for saving fuel. The key to saving fuel is to see yourself.

虽然冬季汽车油耗会比较高，但是省油的小技巧还是有很多的。对于现在的油价那么贵，如果能够让汽车每一升油都发挥价值，跑的尽可能远，日积月累，也是能省不少钱的

Although the car's fuel consumption will be higher in winter, there are still many tips for saving fuel. For today's oil price is so expensive, if we can make every liter of oil of the car give full play to the maximum value, run as far as possible and accumulate over time, we can also save a lot of money
