刚换完机油,发动机噪音变大跟机油有关系吗?
发布者: 发布时间:2017-09-05 浏览量:

 

 

 我们为什么要定期更换机油呢?机油对于发动机就如同血液对于心脏一样重要。机油中含有多种添加剂,能够有效保护发动机重要的移动部件,保证发动机的一个正常运作。

不过有车主反应,刚换完机油之后,发动机噪音变大了?

 

 

Why do we need to oil change on a regular basis? The oil for the engine is just as important as blood to the heart. Oil contains a variety of additives, can effectively protect the engine moving parts, to ensure a normal operation of engine.
But the owner reaction, just after changing the oil, increasing the engine noise?
 

 

 

                         冷车启动造成噪音偏大

汽车的磨损90%以上发生在冷启动这个时候,这个估计大部分车友都没意见,因为冷车状态,机油80%以上基本都回流到油底壳,此时发动机内部机件缺少润滑。

当冷车启动的时候,发动机温度低,机油的润滑性能没有达到最佳状态,加之发动机为了更快预热,提高转速,因而造成噪音偏大,热车之后,噪音和转速又都会降下来,这个是正常情况,无需过多担心。

如果热车有依然没有恢复正常,建议去维修厂检查原因,排除故障。

Cold start big noise
Auto wear more than 90% occurred in cold start at this time, the estimated that most cyclists have no opinion, because of the cold state, oil more than 80% of basic back into the oil pan, the engine internal parts lack of lubrication.
When cold start, the engine temperature is low, the engine oil lubrication performance wasn't up to the best state, together with the engine in order to faster preheating, improve the speed, thus causing large noise, after heat, noise and speed will come down again, this is normal, need not worry too much.
Heat if the car is still not back to normal, it is recommended that a repair shop to check the reason, troubleshooting.
 

 

缺机油导致噪音大


缺机油的情况有多种,例如发动机渗机油,漏机油,正常消耗机油,车主不知道爱车加多少机油,部分车出现烧机油,烧机油之后,有些部件润滑不到位,就会出现声音加大。

以前用高粘度机油,现在换了低粘度机油,如车辆手册上本来要求用5W30,很多车友没留意,直接给用上了5W-40的机油,结果用上后感觉不合适自己的车,后来换上5W30后,刚开始噪音大,开一段时间后又降下来了,这个是正常情况。 

如声音一直下不来,就不正常了,建议换上手册上要求的标号最好, 提示:车辆到一定里程了,比如6~8万公里后,发动机内部间隙增大,换上了更高粘度的机油,通常不建议再换回低粘度的,因为换回低粘度机油后,需要重新磨合,会加剧磨损机件,噪音大。

 


Lack of oil, there are many such as engine oil, engine oil leakage, normal oil consumption, car owners don't know how much oil, love a part of the car came to burn oil, after burning oil, lubrication does not reach the designated position, some parts will appear more sound.

Used with high viscosity oil, now in the low viscosity oil, such as vehicle brochure request with 5 w30 originally, if you have a lot of didn't pay attention to, directly to use 5 w - 40 oil, the results don't feel right after using their own cars, which after five w30, noisy, beginning open again after a period of time down, this is normal.

Such as voice has come down, is not normal, suggest change required in the manual label, best tip: to a certain range of the vehicle, such as after 6 ~ 80000 km, the engine internal clearance increases, changed the higher viscosity of oil, usually it is not recommended to switch back to low viscosity, because in return for low viscosity oil after, need to adjust, will aggravate the wear parts, the noise is big.

 

 

机油超范围使用导致噪音大

机油长期处于一个高温高压的恶劣环境工况下工作,发动机对机油的性能要求也很高,如果使用的时间或者公里数超范围了。

随着机油的流动性,清洁,润滑等性能丧失,从而造成噪音加大,甚至还会引发其他各方面的问题,建议车友按照车辆使用手册上的保养说明按时保养,或者按照机油桶上的说明来保养。

不同品牌用的技术配方不同,不同的配方可能会产生不良化学反应,改变其本身自有的特性,对润滑系统机件造成磨损,噪音变大。

很多混加出现问题的,所以,建议车友们最好不要混加机油,尽量使用同一品牌的机油。

如遇特殊情况更换不同品牌机油,最好换牌不换标,既车辆手册上建议什么粘度机油,用另外品牌的机油还是用这个粘度。

Big oil beyond use lead to noise

Oil has long been at a high temperature and high pressure of work under the bad environment condition, engine performance requirements for engine oil is also very high, if you use a time or make the mileage.
As the oil liquid, cleaning, lubricating performance, such as loss, thereby increasing the noise, and even can cause other problems, if you have Suggestions according to the vehicle maintenance manual, and the results show that maintenance on time, or follow the instructions in the oil barrels to maintenance.
Different brand with different technical formula, different formulations may produce adverse chemical reaction, change itself has its own features, cause of lubrication system machine wear and noise.
A lot of mixed with problems, so, it is recommended that drivers is best not to mix oil, try to use the same brand of engine oil.
In case of special circumstances change different brand oil, had better change the card is not standard, both the vehicle manual what advice on the viscosity of oil, with oil or other brand with the viscosity.
 

更换不同品牌机油后噪音大


不同品牌使用的基础油和添加剂配方不尽相同,通常发动机需要一段时间(大概500公里左右)来重新磨合适应新品牌的机油,刚开始噪音有点大,发动机其它方面,比如动力,油耗等表现出色,通常磨合一段时间噪音就会降下来,这是正常现象。

如500~1000公里噪音仍未降下来,其它方面也无优异表现,说明新的品牌不适合自己车,建议马上换掉。

 

Different brands use of base oil and additive formula is not the same, usually engine over a period of time (about 500 km) to adjust to adapt to the new brand of engine oil, at first, noise is a little big engine other aspects, such as the power, fuel consumption, such as noise usually running in a period of time will come down, this is normal phenomenon.
Such as 500 ~ 1000 km noise still not come down, other performances, shows that the new brand is not suitable for your car, proposed to replace immediately.

 

误加劣质机油导致的噪音大


劣质机油它的抗磨,清洁,润滑保护等性能都非常差,不幸加入后,润滑部件得不到有效保护,磨损加剧,噪声大,如未及时更换更会严重损坏发动机,导致大修,绝对不正常,车友们不要贪小便宜吃大亏。

 


Inferior oil its antiwear, cleaning, lubricating protection performance is very poor, unfortunately after joining, lubrication components can not get effective protection, wear, noise is big, if not timely replacement will seriously damage the engine, lead to overhaul, absolutely is not normal, drivers don't be penny wise, pound foolish.
