Diesel Oil vs. Gasoline Oil: Key Differences
First and foremost, the API classification varies. For diesel engines, you will find oils designated with an 'C' prefix, whereas gasoline engines use 'S.' in their specifications.
Flame temperature during combustion also distinguishes the two. Diesel oil燃烧时产生的火焰温度高达1800°C, contrasting with gasoline oil's relatively lower figure of 600°C.
Another significant distinction is the viscosity. Diesel engines, operating in harsher conditions, require oils with higher viscosity to better withstand the stresses and protect the engine components.
Function and Importance of Oil
机油在发动机中扮演着至关重要的角色。它能够有效地 reduce friction and combat high temperatures, minimizing leaks of gases, and guarding against external pollutants. It shields the engine parts from exposure to water, air, acidic fumes, and other harmful substances. Furthermore, it cleanses the surfaces of the moving parts by flushing away accumulated dirt and debris.
