机油日常使用不可贪多过量

机油日常使用不可贪多过量
daily use of engine oil should not be excessive
汽车润滑油在维修保养时使用的频率非常高。优质润滑油除了能保护发动机、减少换油的次数外,还能节省汽油开销。在这个季节,同时也要注意不要因润滑油使用不当引起汽车故障,不当的使用方法一般源于车友对润滑油的四种误解。为此,有关技术人员给予了专业的解释:
Automobile lubricating oil is frequently used in maintenance. High quality lubricating oil can not only protect the engine and reduce the number of oil changes, but also save gasoline costs. In this season, we should also pay attention not to cause car failures due to improper use of lubricating oil. Improper use methods generally stem from Four Misunderstandings of lubricating oil by car users. For this reason, relevant technicians gave professional explanations:
误解一:润滑油能多加就多加
Misunderstanding 1: add more lubricating oil if 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,使燃油消耗增大。
The amount of lubricating oil should be controlled between the upper and lower scale lines of the oil dipstick. Because too much lubricating oil will rush into the combustion chamber from the gap between the cylinder and the piston to form carbon deposits. These carbon deposits will increase the compression ratio of the engine and increase the tendency to knock; The carbon deposit in the cylinder is in a red hot state, 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 accelerate the pollution of lubricating oil. Secondly, too much lubricating oil increases the mixing resistance of the crankshaft connecting rod and increases the fuel consumption.
误解二:什么时候润滑油变黑了就该换油了
Misunderstanding 2: when the lubricating oil turns black, it's time to change the oil
这种理解并不全面。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 comprehensive. For lubricants without detergent dispersants, the darkening of the color is indeed a sign that the oil has seriously deteriorated, but the lubricants used in modern cars are generally added with detergent dispersants. This kind of detergent washes the adhesive film and black carbon deposits adhered to the piston and disperses them in the oil, reducing the formation of high-temperature deposits in the engine. Therefore, the lubricating oil is easy to turn black after being used for a period of time, but the oil at this time is not completely deteriorated.
误解三:润滑油经常添不用换
Misunderstanding 3: lubricating oil is often added without changing
经常检查润滑油是正确的,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。
Regular inspection of lubricating oil is correct, but only replenishment without replacement can only make up for the shortage of oil quantity, but can not fully 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, which will reduce the quantity.
误解四:添加剂用处大
Myth 4: additives are of great use
真正优质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*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。
The real high-quality lubricating oil is the finished product with a variety of engine protection functions. The formula already contains a variety of additives, including anti-wear agents, and the lubricating oil * pays attention to the balance of the formula to ensure the full play of various properties. Adding other additives by oneself can not bring additional protection to the vehicle, but it is easy to react with the chemicals in the engine oil, resulting in the decline of the comprehensive performance of the engine oil.
