About me
Clarify the objectives of motor oils, including engine oil function, lubrication of internal combustion engines, oil composition, specifications, approvals, and recommendations, API service classification, additives, basic properties, and viscosity.
Engine Oil Functions
Lubrication System
Identify how base oils and additives influence lubricant properties, including viscosity, deposit control, and extreme pressure performance, through a comparative view of base stock and additive impacts.
Discover how viscosity controls lubricant film thickness to prevent asperity contact and friction between moving surfaces, while risking starvation or seizure if the film is too thick or too thin.
Explore total base number as a key measure of lubricant condition, how basic additives neutralize acids, and how Deben titration assesses remaining neutralizing capacity in fresh and used oils.
Learn how SAE viscosity grades describe an oil’s cold and hot performance, including multigrade options like 5w-30 and 10w-40, and how temperature ranges affect engine lubrication.
Compare API performance levels in motor oils, noting multiple levels and the latest Espie introduced for gasoline vehicles in 2021. The Saeki level was brought to the market in 2080.
Explore field examples of motor oils, including dilation and consumption, exhaust emissions, oil storage issues, temperature sensitivity, and improper oil transfer practices.
In this course the student will gain the essential understanding and knowledge about the automotive engine lubricants. We are going to explore the base oils, will do a comparison of 4 cSt base oils from different group. We are going to see what an oil composition, how automotive engine lubricants are formulated. Also we are going to explore the basic engine oil functions, basic engine oil properties, such as viscosity, flash point. Further we are going to explain what API, ACEA and SAE mean. Why SAE viscosity is important when choosing the right lubricant, how API or ACEA performance level helps us choose the right oil for the right application. That mean the choosing the right SAE viscosity should be appropriate to the working conditions e.g. driving conditions in which the ICE will work. How the oil is have to be ale to resist oxidation, formation of sludge and other negatives effects occuring in the while the automotive engine oil have to have perfect balance whether is new or old, since it changes his composition with the usage e.g. driving. That perfect balance is a key to superior performance of the engine oil, with out affecting the engine work. By the end of the course he should be able to choose the right oil for appropriate application.
