Motor oil意思

"Motor oil" 是指用於內燃機（如汽車、機車、飛機、船舶等）的潤滑油。它的工作原理是在發動機內部各個運動部件之間形成一層保護膜，減少摩擦和磨損，同時還能幫助散熱、清潔發動機內部、防止腐蝕，並密封汽缸和活塞環之間的間隙以減少氣體的洩漏。

Motor oil comes in different grades and types, each designed for specific applications and conditions. The choice of motor oil depends on factors such as the type of engine, the climate, and the manufacturer's recommendations. It's important to use the correct type of motor oil to ensure the proper functioning and longevity of the engine.
