四个关于汽车润滑油的误区

来源:https://www.smxnykj.com/ 发布时间:日期:2022-09-15
误解一:润滑油经常添不用换
Misunderstanding 1: lubricating oil often needs to be replaced
经常检查汽车润滑油是正确的,但只补充不更换只能弥补机油数量上的不足,却无法完全补偿润滑油性能的损失。润滑油在使用过程中,由于污染、氧化等原因质量会逐渐下降,同时还会有一些消耗,使数量减少。
It is correct to check the automobile lubricating oil frequently, but only replenishing without replacing can only make up for the shortage of oil quantity, but cannot completely compensate for the loss of lubricating oil performance. During the use of lubricating oil, the quality will gradually decline due to pollution, oxidation and other reasons. At the same time, there will be some consumption, reducing the quantity.
误解二:添加剂用处大
Misunderstanding 2: additives are of great use
高质量的润滑油是具备多种发动机保护功能的成品,配方中已含有多种添加剂,其中包括抗磨剂,而且润滑油更讲究配方的均衡以保障各种性能的充分发挥。自行添加其他添加剂不仅不能给车辆带来额外保护,反而易与机油中的化学物质发生反应,造成机油综合性能的下降。
High quality lubricating oil is a finished product with a variety of engine protection functions. The formula already contains a variety of additives, including anti-wear agents. Moreover, the lubricating oil pays more attention to the balance of the formula to ensure the full play of various performances. Self adding other additives will not bring additional protection to the vehicle, but will easily react with the chemicals in the engine oil, resulting in the decline of the comprehensive performance of the engine oil.
误解三:什么时候润滑油变黑了就该换油了
Misunderstanding 3: When the lubricating oil turns black, it's time to change it
这种理解并不全的。对于没有加清静分散剂的润滑油来说,颜色变黑的确是油品已严重变质的表现,但现代汽车使用的润滑油一般都加有清静分解剂。这种清静剂将粘附在活塞上的胶膜和黑色积炭洗涤下来,并分散在油中,减少发动机高温沉淀物的生成,故润滑油使用一段时间后颜色容易变黑,但这时的油品并未完全变质。
This understanding is not complete. For the lubricating oil without detergent dispersant, blackening is indeed a sign of serious deterioration of the oil, but the lubricating oil used in modern cars is generally added with detergent dispersant. This tranquilizer washes the adhesive film and black carbon deposit on the piston and disperses them in the oil to reduce the generation of high-temperature deposits in the engine. Therefore, the color of the lubricating oil tends to turn black after a period of use, but the oil is not completely deteriorated at this time.
误区四:润滑油能多加就多加
Mistake 4: Add as much lubricant as you can
润滑油量应该控制在机油尺的上、下刻度线之间为好。因为润滑油过多就会从气缸与活塞的间隙中窜入燃烧室燃烧形成积炭。这些积炭会提高发动机压缩比,增加产生爆震的倾向;积炭在汽缸内呈红热状态还容易引起早燃,如落入汽缸会加剧汽缸和活塞的磨损,还会加速污染润滑油。其次,润滑油过多增加了曲轴连杆的搅拌阻力,使燃油消耗加大。
The amount of lubricating oil should be controlled between the upper and lower scale marks of the oil dipstick. Because too much lubricating oil will rush into the combustion chamber from the clearance between the cylinder and the piston to form carbon deposits. These deposits will increase the compression ratio of the engine and increase the tendency to produce detonation; The carbon deposit in the cylinder is red hot, which is also easy to cause early combustion. If it falls into the cylinder, it will aggravate the wear of the cylinder and piston, and also accelerate the pollution of lubricating oil. Secondly, excessive lubricating oil increases the stirring resistance of the crankshaft connecting rod, which increases fuel consumption.
