汽車在使用期間不可能說一點(diǎn)問題都不會出現(xiàn)，這不近來有人反應(yīng)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(jī)油會變粘稠使?jié)櫥Ч档?。冷車啟動時發(fā)動機(jī)中各種機(jī)械配件受機(jī)油影響，運(yùn)行時摩擦阻力增加，導(dǎo)致噪音過高，但是隨著車輛的運(yùn)轉(zhuǎn)，機(jī)油的溫度升高，發(fā)動機(jī)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(qū)，冬季外界溫度較低時，冷啟動后短時間內(nèi)機(jī)油未達(dá)到很好的潤滑效果，發(fā)動機(jī)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(dǎo)致異響。對于種情況，此屬正常現(xiàn)象，無需擔(dān)心；對于第二種情況不屬于質(zhì)量問題，必須注意車輛的正確使用及保養(yǎng)，盡量避免積碳的產(chǎn)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(yè)的維修廠處保養(yǎng)，使用優(yōu)質(zhì)燃油；車輛應(yīng)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(jī)油比較粘稠。此時，機(jī)油不能給發(fā)動機(jī)帶來良好的潤滑。此時發(fā)動機(jī)內(nèi)各部件之間的摩擦力比較大。當(dāng)然，發(fā)動機(jī)的噪音會更大。一些。機(jī)油被稱為發(fā)動機(jī)的血液。如果發(fā)動機(jī)內(nèi)沒有機(jī)油，發(fā)動機(jī)就不能正常運(yùn)轉(zhuǎn)。機(jī)油不僅對發(fā)動機(jī)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(fā)動機(jī)運(yùn)轉(zhuǎn)時，機(jī)油會在發(fā)動機(jī)各部件表面形成一層油膜，可避免發(fā)動機(jī)各部件直接接觸產(chǎn)生的摩擦。如果發(fā)動機(jī)中的各個部件直接接觸產(chǎn)生摩擦，會增加發(fā)動機(jī)的磨損，還可能影響發(fā)動機(jī)過熱。如果發(fā)動機(jī)繼續(xù)在過熱狀態(tài)下運(yùn)行，將會影響發(fā)動機(jī)氣缸。如果將發(fā)動機(jī)從氣缸中拉出，修理它的成本非常高。機(jī)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(jì)南哪里修奧迪比較專業(yè)的人員建議機(jī)油需要定期更換。如果長期不更換，會影響發(fā)動機(jī)的潤滑和散熱。每次更換機(jī)油時，必須將機(jī)油濾清器濾芯一件式更換。機(jī)油濾清器的作用是過濾機(jī)油。如果沒有機(jī)油濾清器，一段時間后機(jī)油可能會變臟。購買機(jī)油和機(jī)油濾芯時，一定要從正規(guī)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.
