汽車在使用期間不可能說一點問題都不會出現，這不近來有人反應汽車在冬季冷啟動時響聲會很大，這是什么原因呢？

It's impossible to say that no problems will appear during the use of the car. Recently, some people have reported that the car will make a loud noise during cold start in winter. What's the reason?

由于冬天的溫度很低，機油會變粘稠使潤滑效果降低。冷車啟動時發動機中各種機械配件受機油影響，運行時摩擦阻力增加，導致噪音過高，但是隨著車輛的運轉，機油的溫度升高，發動機的噪音會逐漸下降至正常水平。

Due to the low temperature in winter, the oil will become viscous and reduce the lubrication effect. During cold start, various mechanical parts in the engine are affected by the oil, and the friction resistance increases during operation, resulting in too high noise. However, with the operation of the vehicle, the temperature of the oil increases, and the noise of the engine will gradually drop to the normal level.

在北方地區，冬季外界溫度較低時，冷啟動后短時間內機油未達到很好的潤滑效果，發動機可能會有輕微的響聲；由于氣門存在積碳可能造成間隙過大，導致異響。對于種情況，此屬正常現象，無需擔心；對于第二種情況不屬于質量問題，必須注意車輛的正確使用及保養，盡量避免積碳的產生。

In the north, when the external temperature is low in winter, the engine oil does not achieve good lubrication effect in a short time after cold start, and the engine may make a slight sound; Due to the carbon deposit on the valve, the clearance may be too large, resulting in abnormal noise. For the first case, this is a normal phenomenon and there is no need to worry; The second case is not a quality problem. Attention must be paid to the correct use and maintenance of the vehicle to avoid carbon deposition as far as possible.

建議是定期到專業的維修廠處保養，使用優質燃油；車輛應時常跑跑高速，使用原廠專用的燃油添加劑。

It is recommended to go to a professional repair shop for maintenance on a regular basis and use high-quality fuel; The vehicle shall always run at high speed and use the original special fuel additive.

冬季冷啟動后，機油比較粘稠。此時，機油不能給發動機帶來良好的潤滑。此時發動機內各部件之間的摩擦力比較大。當然，發動機的噪音會更大。一些。機油被稱為發動機的血液。如果發動機內沒有機油，發動機就不能正常運轉。機油不僅對發動機起潤滑作用，還起到清潔、密封、緩沖、防銹、散熱等作用。

After cold start in winter, the oil is viscous. At this time, the oil cannot bring good lubrication to the engine. At this time, the friction between various components in the engine is relatively large. Of course, the noise of the engine will be greater. Some. Oil is called engine blood. If there is no oil in the engine, the engine will not operate normally. The engine oil not only lubricates the engine, but also plays the roles of cleaning, sealing, buffering, rust prevention, heat dissipation and so on.

發動機運轉時，機油會在發動機各部件表面形成一層油膜，可避免發動機各部件直接接觸產生的摩擦。如果發動機中的各個部件直接接觸產生摩擦，會增加發動機的磨損，還可能影響發動機過熱。如果發動機繼續在過熱狀態下運行，將會影響發動機氣缸。如果將發動機從氣缸中拉出，修理它的成本非常高。機油的各項性能基本都會隨著長期使用而下降。

When the engine is running, the oil will form an oil film on the surface of all parts of the engine, which can avoid the friction caused by direct contact of all parts of the engine. If all parts of the engine are in direct contact to produce friction, it will increase the wear of the engine and may also affect the overheating of the engine. If the engine continues to operate in an overheated state, it will affect the engine cylinder. If the engine is pulled out of the cylinder, the cost of repairing it is very high. The performance of engine oil will basically decline with long-term use.

濟南哪里修奧迪比較專業的人員建議機油需要定期更換。如果長期不更換，會影響發動機的潤滑和散熱。每次更換機油時，必須將機油濾清器濾芯一件式更換。機油濾清器的作用是過濾機油。如果沒有機油濾清器，一段時間后機油可能會變臟。購買機油和機油濾芯時，一定要從正規渠道購買，一定要選擇大品牌的正品。

Where to repair Audi in Jinan? More professional personnel suggest that the engine oil needs to be replaced regularly. If it is not replaced for a long time, it will affect the lubrication and heat dissipation of the engine. The oil filter element must be replaced in one piece each time the oil is changed. The function of the oil filter is to filter the oil. If there is no oil filter, the oil may become dirty after a period of time. When buying engine oil and engine oil filter element, you must buy it from formal channels and choose genuine products of large brands.
