What is the difference between diesel engine oil and gear oil?
Lubricating oil is a generalized term, lubricating oil contains oil, grease, gear oil, black oil and so on, is the role of lubrication, reduce mechanical friction, reduce wear, to prevent the engine from overheating, to ensure the normal operation of the machine can work. According to the mechanical environmental requirements, determine the use of different types and different types of lubricating oil for example: you have to use the gasoline engine, diesel engine, gasoline engine oil; we have to use the diesel engine. The gasoline engine, the engine compression ratio of different to choose different types of gasoline engine oil.
Engine oil, formerly a general term for lubricants, represents the lubricating oil used on the machine. Now it is used for lubricating oils of various enginesOil for the engine just as blood for heart as important. The engine is the heart of the car, the engine has a lot of friction between the movement of the metal surface, the speed of these components move fast, poor environment, work temperature is 400 degrees centigrade to 600 degrees centigrade. In such bad working conditions, only qualified lubricating oil can reduce engine wear parts, prolong the service life.
There are 3 kinds of lubricant used in automobiles, lubricating oil, gear oil and lubricating grease. Lubricating oil is the most widely used lubricant in various engines. Its functions are lubrication, cooling, protection and cleaningThe gasoline engine oil is extracted from the underground mining wells, this without any oil refining is not suitable for the engine, so must be strictly refining, adding a variety of elements, so as to effectively suppress the cold and high temperature is not stable.Also known as the transmission gear oil lubricating oil, mainly used for lubrication of automobile and tractor transmission gearbox, reducer and differential gears, gear oil lubricating oil viscosity is large, slightly black, so it is called black oil. Due to different gear tooth profile, gear oil has different requirements, general is divided into ordinary gear oil and hypoid gear oil. They should be according to the requirement of filling, varieties should not be confused.Grease containing thickening agent, its nature and different oil. Due to the vast majority of grease is semi solid, can maintain their shape at room temperature in the vertical surface erosion. Lubricating oil is generally yellow, so commonly known as butter. Grease is widely used in automobile parts lubrication bearings, bushings and steel springs.
