汽车在冬季冷启动时响声特别大的原因

来源:http://www.lutongqixiu.com/ 日期:2022-05-17 发布人:lutong
汽车在使用期间不可能说一点问题都不会出现,这不近来有人反应汽车在冬季冷启动时响声会很大,这是什么原因呢?
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?
由于冬天的温度很低,机油会变粘稠使润滑效果降低。冷车启动时发动机中各种机械配件受机油影响,运行时摩擦阻力增加,导致噪音过高,但是随着车辆的运转,机油的温度升高,发动机的噪音会逐渐下降至正常水平。
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.
在北方地区,冬季外界温度较低时,冷启动后短时间内机油未达到很好的润滑效果,发动机可能会有轻微的响声;由于气门存在积碳可能造成间隙过大,导致异响。对于种情况,此属正常现象,无需担心;对于第二种情况不属于质量问题,必须注意车辆的正确使用及保养,尽量避免积碳的产生。
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.
建议是定期到专业的维修厂处保养,使用优质燃油;车辆应时常跑跑高速,使用原厂专用的燃油添加剂。
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.

冬季冷启动后,机油比较粘稠。此时,机油不能给发动机带来良好的润滑。此时发动机内各部件之间的摩擦力比较大。当然,发动机的噪音会更大。一些。机油被称为发动机的血液。如果发动机内没有机油,发动机就不能正常运转。机油不仅对发动机起润滑作用,还起到清洁、密封、缓冲、防锈、散热等作用。
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.
发动机运转时,机油会在发动机各部件表面形成一层油膜,可避免发动机各部件直接接触产生的摩擦。如果发动机中的各个部件直接接触产生摩擦,会增加发动机的磨损,还可能影响发动机过热。如果发动机继续在过热状态下运行,将会影响发动机气缸。如果将发动机从气缸中拉出,修理它的成本非常高。机油的各项性能基本都会随着长期使用而下降。
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.
济南哪里修奥迪比较专业的人员建议机油需要定期更换。如果长期不更换,会影响发动机的润滑和散热。每次更换机油时,必须将机油滤清器滤芯一件式更换。机油滤清器的作用是过滤机油。如果没有机油滤清器,一段时间后机油可能会变脏。购买机油和机油滤芯时,一定要从正规渠道购买,一定要选择大品牌的正品。
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.
