Learning outcomes of the course unit:
Student understands the physical and chemical processes of processing and use of gaseous, liquid and solid fuels of fossil origin and renewable energy sources. Student gain knowledge about the method of production and the quality of automotive fuels. Student understands processes of production of petroleum and synthetic oils, their properties, additives to improve performance of lubricants. The student has knowledge on the relationship between the composition, properties and use of specific fuels and lubricants. The student understands the impact of fuels and lubricants to the environment, as well as the processing of used lubricating oils.
