• Semester 4, position 4

To provide students with theoretical and practical knowledge about the basics of IC engine working process; To introduce students to the various types and applications of the IC engines; To provide students with the opportunities to develop and acquire sense for basic engineering designing skills through numerous examples of problems solved on a heat machine widely used more than a century;

Acquired theoretical and practical knowledge of the design of engine parts and systems train the students for practice in engine exploitation and maintenance in all technical field of engine application. Gained knowledge is the basic for deeper study during further Msc degree schooling with the aim to train the students for complex problems of the designing of engine parts, systems and the whole engines.

1. IC engine working process principles; spark ignition and diesel; four stroke and two stroke process 2. IC engines classification and types; design specifics in various fields of engine application. 3. Design of engine stationary parts; downer and upper engine case, engine block and cylinder liner; cylinder head. 4. Design of main engine moving parts; piston assembly – piston, piston rings, piston pin; design of connecting rod and crankshaft. 5. Design of engine gas exchange system. 6. Design of engine cooling system - liquid and air cooling. 7. Design of engine lubricating system. 8. Design of engine starting system.

a) Auditoria exercises: 1. Engine piston mechanism and engine characteristic designs. Display of the characteristic designs of engine stationary and moving parts. Display of engine gas exchange systems characteristic designs. 3. Design of engine cooling and lubricating systems; evaluation of required capacity of engine cooling and lubricating systems. b) Laboratory exercises: 1. Display of engine parts design, various engine types and engine systems. 2. Disassembling and assembling of spark ignition engine. 3. Disassembling and assembling of diesel engine.
