The aim of the course is to introduce the student to the fundamental principles of operation of Internal Combustion Engines. The student should understand the design and operation of the basic equipment of the MEK, (piston MEK – gas turbines), the basic types of combustion chambers (gasoline engine, diesel, GDI), and become able to carry out basic calculations on the main components of the MEK, their subsystems, balancing, as well as to understand their control and diagnostic systems (engine management systems).

1. Introduction:Basic Principles. Historic evolution of Internal Combustion Engine. Reciprocating engine cycles.
2. Design Construction materials of engine components – subsystems. Main categories of reciprocating engines. Vehicle engines. Naval engines. Static engines. Airplane engines.
3. Engine design and operation parameters. Thermochemistry of flammable air fuel mixtures. Thermophysical properties software. A/F calculation based on exhaust gas composition.
4. Engine breathing processes. Flow through valves -ports. Supercharging. Mixture preparation in SI engines.
5. Flow in the cylinder. Combustion in Spark Ignition engines. Thermodynamic Analysis computation of fuel burning rates by analysis of indicator diagram. Flame structure propagation engine knock.
6. Combustion in diesel engines. IDI and DI combustion chambers. Diesel fuel injection systems. Fuel jet behaviour, droplet distribution. Droplet vaporization -ignition. Ignition delay. Gasoline Direction injection Engines (GDI).
7. Heat transfer in reciprocating engine cooling systems. Computation of thermal loading of engine components (piston cylinder head, cylinder liners, exhaust valves).
8. Diesel engine simulatio. SI simulation.
9. Engine friction and lubrication. Introduction to tribology
10. Pollutant formation and control in SI and Diesel Engines.
