**课程名称：** 汽车工程：发动机润滑系统 **课程概述：** 本课程深入探讨了发动机润滑系统的基本功能和组成部分。学员将了解润滑系统在内燃机中的六大主要功能，以及压力润滑和飞溅润滑等主要润滑方式。课程还将详细介绍润滑油的各项重要性质，包括闪点、倾点、粘度、粘度指数，以及发动机中的油压信号。 学员还将学习润滑油术语，包括润滑油的等级划分，如何根据气候条件选择合适的润滑油等级。此外，课程还将提供分步指南，教导如何校准润滑油尺，特别是在更换丢失或有缺陷的油尺时，强调更换机油和滤清器，并确保安装OEM规定的机油量。正确的校准步骤包括运行发动机，停歇后测量并标记高位刻度，然后根据旧油尺的低位刻度距离标记新油尺。 最后，课程还将涵盖润滑系统的故障诊断。 **课程大纲：** 未提供
Basic Functions of lubrication system-Six main functions of Lubrication subsystemsBasic components of lubrication system-Basic components of the lubrication systems Types of lubrication in IC engines-Pressure lubrication , Splash lubricationProperties of Lube oils-Flash point, pour point, viscosity, Viscosity index, Oil pressure signal in EnginesLube oil terminology-grades of lubrication , How to judge the grades of lube oil and climatic conditions in which the oil must be used Calibrate lube oil dipstick-When replacing a missing or defective dipstick, replace the engine oil and filters, installing the exact OEM specified quantity. Run the engine for a couple of minutes then shut down and leave for 10 minutes. Dip the oil sump with the new dipstick and scribe the high level graduation with an electric pencil. Measure the distance from the high-level to low-level graduations on the old dipstick and then duplicate on the replacement.Calibrate lube oil dipstick-When replacing a missing or defective dipstick, replace the engine oil and filters, installing the exact OEM specified quantity.
