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!

為什么小排量的車油耗高更加明顯？

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

因?yàn)樾∨帕寇囎灾剌p意味著只需要較少的燃料消耗產(chǎn)生的不大牽引力即可克服其自重帶來(lái)的阻力,在平時(shí)百公里油耗會(huì)很低。但是冬季會(huì)如前所述,潤(rùn)滑油和潤(rùn)滑脂黏度增加會(huì)需要額外的燃料作功來(lái)克服阻力,升溫保溫也會(huì)需要消耗額外的燃料,并且小排量車發(fā)動(dòng)機(jī)比較輕巧,缸體缸壁較薄,汽缸內(nèi)的高溫向外散失會(huì)相對(duì)容易,升溫保溫消耗的燃料會(huì)更加明顯。

 

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.

同時(shí)由于平時(shí)油耗低,冬季即使油耗只增加不到1升，但是相對(duì)油耗也可能增加了百分之十幾甚至二十,增幅會(huì)顯得很大。

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.

也正是由于這種原因，大排量的汽車油耗增加反而沒(méi)那么明顯了，1升油僅會(huì)增加百分之幾，而且大排量的汽車，發(fā)動(dòng)機(jī)的缸壁相對(duì)于小排量的車更厚一點(diǎn)，所以熱損失也會(huì)相對(duì)慢一些，排量大，產(chǎn)生熱量也高。

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.

如何應(yīng)對(duì)冬季油耗高？

How to deal with high fuel consumption in winter?

1、注意輪胎氣壓和磨損

1. Pay attention to tire pressure and wear

由于冬季氣溫低，輪胎內(nèi)的氣壓會(huì)出現(xiàn)明顯下降，并且輪胎膠質(zhì)變硬，使輪胎的附著力變差，輪胎附著力的降低會(huì)導(dǎo)致車輛動(dòng)力傳遞效率變低，油耗增加也就在所難免。

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、不要長(zhǎng)時(shí)間高速行駛

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

任何一款車都有經(jīng)濟(jì)時(shí)速，高速行駛會(huì)增加空氣阻力，從而增加油耗。此外，也要避免頻繁的急加速和急剎車，保持勻速行駛。

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、平時(shí)要加強(qiáng)對(duì)車的保養(yǎng)

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

車輪軸承應(yīng)按時(shí)上油，可減少摩擦力，從而降低油耗，還有機(jī)油黏度，也會(huì)導(dǎo)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、上述三點(diǎn)其實(shí)都是外部因素，內(nèi)部因素還是自己的駕駛習(xí)慣，比如不急加速、不急剎車、緩慢起步，這些都是省油的一些小技巧，想省油更關(guān)鍵的還是要看自己。

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.

雖然冬季汽車油耗會(huì)比較高，但是省油的小技巧還是有很多的。對(duì)于現(xiàn)在的油價(jià)那么貴，如果能夠讓汽車每一升油都發(fā)揮價(jià)值，跑的盡可能遠(yuǎn)，日積月累，也是能省不少錢的

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
