Course objective:

Course objective: Understanding, use, handling, and storage of all types of fuels and lubricants.

Course contents:

Fuels: definition of technical fuels. Classification of fuels. Elemental composition of fuel. Basic properties of solid, liquid and gaseous fuels. Processing of crude oil. Chemical structure of liquid fuels. Classification and properties of liquid fuels according to use: diesel fuels, motor gasolines, jet fuels, biodiesel, liquefied petroleum gas (LPG), compressed natural gas (CNG). Fuel physical and chemical properties: density, heating value, lubricity. Otto engine knocking. Fuel octane rating. Diesel engine detonation. Ignition delay period. Cetane number. Fuel additives. Fuel retention. Fuel aging processes. Fuel storage and transport. Lubricants: fundamentals of tribology, friction and 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. Special purpose oils and liquids. Handling and storage of lubricants.


Knowledge and skills needed to perform tasks related to the maintenance of road and special motor vehicles, with a focus on proper selection and use of fuels, lubricants and special purpose liquids.

Learning outcomes:

Having passed the exam, the student will be able to: 1. Analyse important fuel and lubricant properties for the application in specific conditions of exploitation 2. Compare the values of important physical properties of fuels and lubricants. 3. Critically judge the values of important physical properties of fuels and lubricants for the application in a specific working condition. 4. Select fuels and lubricants for the application in specific conditions of exploitation. 5. Plan the measurement of important physical properties of fuels and lubricants. 6. Verify the compliance of data obtained for the properties of prescribed magnitudes with legal norms. 7. Organise the handling and storage procedures for fuels and lubricants. These learning outcomes contribute to the following outcomes of the study programme of motor vehicle maintenance: - Explain the impact of harmful motor vehicle emissions on people, the environment and protective measures. - Analyse the causes and effects of vehicle malfunctions. - Demonstrate professional and ethical responsibility in motor vehicle maintenance.
