Knowledge and skills necessary for individual setting, description and calculation of thermodynamic states and processes of heat engines, individual calculation of thermal states of heat engines as thermodynamic systems. This refers to the single parts and the system as a whole, when the objective is a calculation check, or verification of heat engine parameter. Knowledge and skills for individual definition of the quality and quantity of steam as a working medium, description and calculation of parameters for the changes of state of steam. Knowledge and skills for the individual selection of fuel, calculation of fuel and air quantities in the combustion chamber, as well as the calculation of combustion efficiency and its environmental acceptability. Knowledge and skills for individual solving of tasks and calculations related to heat transfer, as well as the enhancement - cooling processes of heat engines etc. - and the placing of insulation.

Learning outcomes:

Having passed the exam, the student will be able to: 1. Define thermodynamic (thermal) state and magnitudes of ideal gases and the conditions for the change of state. 2. Describe, define and compare basic thermodynamic processes and calculate the initial and final state of ideal gases: isochore, isobar, isotherm, adiabat and polytrope, using relevant terms. 3. Describe and design a thermodynamic cycle for heat engines, calculate the magnitudes of state for characteristic points, energy exchange, diagrammatic representation and efficiency of thermal transformation - useful activity coefficient in clockwise (dextrorotatory) cycles and work efficiency in counter clockwise (laevorotatory) cycles. 4. Individually design the conditions of combustion processes according to basic functional in order to maximise efficiency and environmental acceptability. 5. Apply the acquired knowledge and skills to solve problems relating to the application of internal combustion engines with an aim of maximised efficiency, environmental acceptability and ethical responsibility.
