Course Objective: A theory/laboratory course provides fundamental knowledge of the handling, storage and exploitation of fuels and lubricants.

Course Contents: Definition of the term fuel. Classification of fuels. Elemental composition of the fuel. Relevant properties and comparison between solid, liquid and gaseous fuels. The origin of oil. Processing crude oil – refining. Chemical structure of liquid fuels. Overview of liquid fuels application – automotive diesel, motor gasoline, aviation fuels, liquified petroleum gas (LPG). Fuel properties: density, aniline point, Engler distillation curve, Reid vapour pressure and volatility, calorific value, solubility, lubricating quality. Engine knock, knocking and octane rating, octane number, octane quality measurement. Diesel knock, ignition delay period, cetane number, diesel fuel additives. Oxidation stability of fuels. Storage of fuels. Biodiesel. Friction and lubrication theory. Types of lubrication. Physical and chemical properties of lubricants. Classification of lubricating oils. Lubricating oils for internal combustion engines. SAE viscosity grades for engine oils. API service classification. Application of lubricating greases. Classification of lubricating greases. Transportation lubricants (engine coolants, brake fluids, transmission fluids). Protective coats. Washing and degreasing liquids. Special consumables. Handling and storage (preservation and replacement) of consumables.

General and Specific Competencies (Knowledge and Skills): After completing this course students will be able to apply the knowledge and skills needed to modern motor vehicle maintenance, especially with regard to proper selection of fuels, lubricants and coolants.
