Many private car owners like to wash their cars in the hot sun. They think that they can dry the car quickly after washing. In fact, it is wrong that when washing cars in the hot sun, the convex lens effect formed by water droplets will cause local high temperature phenomenon on the top layer of the car paint. Over time, the car paint will lose its luster. If waxing at this time, it is easy to cause uneven body color. Therefore, car washing and waxing is best carried out under shaded conditions, if not guaranteed, it is best to choose cloudy or sunny morning and evening time, car owners should understand the following correct maintenance common sense.

　　進口輪胎--不適用

　　Imported tyres - not applicable

　　有些人買輪胎特別喜歡強調“進口”。國外推的新款輪胎對國內的用戶來說有一個致命的缺陷就是不適用。歐洲平整的路面與北京二環(huán)、三環(huán)的路況有較大區(qū)別，適合歐洲路況的輪胎在北京就難有上佳表現，特別是胎側的耐沖擊力方面顯然有些水土不服，就如同穿意大利名牌皮鞋走石子路一般，胎側起包在所難免。一些國外品牌的輪胎在國內合資生產后，都根據國內道路狀況在輪胎側面增加了一層簾子布，從而大大增強了胎側的抗沖擊力，合資生產的輪胎從性能上講完全能夠替代進口貨。

　　Some people especially like to emphasize "import" when buying tyres. The most lethal defect of the new tyres introduced abroad is that they are not suitable for domestic users. The smooth pavement in Europe is quite different from that in Beijing. The tires suitable for European road conditions can hardly perform well in Beijing. Especially in the aspect of tire side impact resistance, it is obvious that there are some incompatibilities, just like wearing Italian brand leather shoes and walking on stony roads. It is inevitable for tire side to pick up and wrap up. Some foreign brands of tires jointly produced in China, according to the domestic road conditions, have added a layer of cord cloth on the side of the tire, thus greatly enhancing the impact resistance of the tire side, and the joint-venture tires can completely replace imports in terms of performance.

　　新蓄電池不充電--縮短壽命

　　New Batteries Not Charged--Shorten Life

　　蓄電池的首次充電稱為初次充電，初次充電對蓄電池的使用壽命有極大的影響。若不充電，即加“水”直接使用，蓄電池的容量不高，壽命將縮短；若直接充電，也會縮短壽命。通常蓄電池的初次充電是在加注完電解液后，用小電流充電大約1小時左右即可安裝使用。

　　The first charge of the battery is called the first charge. The first charge has a great influence on the service life of the battery. If the battery is not charged, that is, "water" is added directly, the capacity of the battery is not high, and the life of the battery will be shortened; if charged directly, the life of the battery will also be shortened. Usually, the initial charge of the battery is about one hour after filling up the electrolyte, and it can be installed and used by charging with a small current.

　　車內設備隨意加--影響行車安全

　　Adding in-car equipment at will affects driving safety

　　私人轎車是車主移動的家，追求乘用舒適和豪華無可厚非，但一些車主自己動手在車內加裝各種設備，這種改裝，如果處理不妥當，對汽車性能及操縱的方便和可靠性往往帶來不利影響，易留下后遺癥或影響行車安全。

　　Private car is the mobile home of the owner. It's justifiable to pursue comfort and luxury. However, some owners install all kinds of equipment in the car by themselves. If this modification is not handled properly, it often brings adverse effects on the convenience and reliability of the car's performance and operation, leaving behind sequelae or affecting driving safety.

　　冷卻水溫度太低--磨損發(fā)動機

　　Cooling Water Temperature Too Low--Wear Engine

　　天氣炎熱的時候，有的司機為了防止發(fā)動機溫度過高，一味要求冷卻水溫度盡可能的低；有的司機為了達到降溫的目的，干脆把節(jié)溫器拆去，這些做法都是不對的。

　　In hot weather, some drivers blindly require the cooling water temperature to be as low as possible in order to prevent the engine from overheating; some drivers simply remove the thermostat in order to achieve the goal of cooling, which is wrong.

　　汽車發(fā)動機既怕熱又怕冷，如果冷卻水溫度過低，會使燃油燃燒惡化，油耗增加，加劇磨損，機油黏度增加，發(fā)動機功率降低。試驗表明，汽車行駛時冷卻水溫度為40-50攝氏度時，發(fā)動機磨損增加60%-80%，功率降低25%，油耗增多8%-10%。因此，發(fā)動機冷卻水的溫度并非越低越好，一般應控制在80-90攝氏度之間。

　　Automobile engine is afraid of both heat and cold. If the cooling water temperature is too low, fuel combustion will deteriorate, fuel consumption will increase, worsen wear, oil viscosity will increase, and engine power will decrease. Experiments show that when the cooling water temperature is 40-50 degrees Celsius, engine wear increases by 60-80%, power decreases by 25%, and fuel consumption increases by 8-10%. Therefore, the engine cooling water temperature is not the lower the better, generally should be controlled between 80 - 90 degrees Celsius.
