如何选用柴油机润滑油?

1、柴油机油是用于压燃式内燃发动机,在性能要求上依转速和平均有效压力或强化系数的不同而选择,柴油机分为低速和高速两种,低速机增压使用普通柴油机油既可,高速、高增压、高强化系数的柴油机一定要使用高级柴油机油。高速柴油机是指转数在1000r/min以上活塞环作用于气缸壁的压力高到3-4MPA,在这样苛刻的条件下,所以柴油机对润滑油的要求比较严格,一定要使用高质量的润滑油,另外柴油机排气烟尘比用无铅的汽油机高出10倍,而这种烟尘吸附二硫磷酸锌分解生成物,降低了二硫磷酸锌的抗磨作用,所以清净分散抗磨添加剂比汽油机多。
1. Diesel engine oil is used for compression ignition internal combustion engine. In terms of performance requirements, it is selected according to the speed, average effective pressure or enhancement coefficient. Diesel engines are divided into low-speed and high-speed engines. Ordinary diesel engine oil can be used for supercharging of low-speed engines, and high-speed, high supercharging and high enhancement coefficient diesel engines must use high-grade diesel engine oil. High speed diesel engine means that the pressure of piston ring acting on the cylinder wall is as high as 3-4mpa when the rotation speed is above 1000r / min. under such harsh conditions, the diesel engine has strict requirements on lubricating oil, and high-quality lubricating oil must be used. In addition, the exhaust smoke of diesel engine is 10 times higher than that of lead-free gasoline engine. The smoke adsorbs the decomposition products of zinc disulfide phosphate, reducing the anti-wear effect of zinc disulfide phosphate, Therefore, there are more clean and dispersed anti-wear additives than gasoline engines.
2、粘度是柴油机选择的主要指标,试验证明在中负荷柴油机上,当活塞速度时应用100℃粘度12-16机油,在小型高速柴油汽车上,冬天就用6-8mm2/s粘度柴机油,夏天应用10-14mm2/s柴油机油。
2. Viscosity is the main index of diesel engine selection. The test shows that on medium load diesel engines, when the piston speed is 100 ℃, the viscosity of 12-16 engine oil is used. On small high-speed diesel vehicles, the viscosity of 6-8mm2 / s diesel engine oil is used in winter, and the viscosity of 10-14mm2 / S diesel engine oil is used in summer.
3、质量等级的选择:柴机油的更主要使用性能选择耐热抗氧化安定性好的柴油机油。
3. Quality grade selection: diesel engine oil with good heat resistance, oxidation resistance and stability is the main performance of diesel engine oil.
柴机油中某些成分受热氧化生成氧化物、有机酸、羟基酸、氮化物、沥青和焦质是发动机发生腐蚀和磨损的主要原因,所以不能随意盲目的选用柴油机油。
Some components in diesel engine oil are oxidized to form oxides, organic acids, hydroxyl acids, nitrides, asphalt and coke, which are the main reasons for engine corrosion and wear. Therefore, diesel engine oil cannot be selected blindly.
