Internal Combustion Engines (96h)
Responsible lecturer prof. dr hab.eng. Antoni Kalukiewicz
Course topics:
- Introduction: This topic introduces and defines the internal combustion engine. Descriptions are given of many engine components and of basic four-stroke and two-stroke cycles for both spark ignition and compression ignition engines.
- Operating Characteristics: This topic examines the operating characteristics of reciprocating internal combustion engines. These include the mechanical output parameters of work, torque, and power; the input requirements of air, fuel, and combustion; efficiencies; and emission measurements of engine exhaust.
- Engine Thermodynamic Cycles: This topic presents the basic cycles used in reciprocating internal combustion engines. The most common four-stroke spark ignition and compression ignition cycles are analyzed in detail using air-standard analysis.
- Thermo chemistry and fuels: This topic reviews basic thermo chemistry principles as applied to internal combustion engines. It studies ignition characteristics and combustion in engines, the octane number of spark ignition fuels, and the cetane number of compression ignition fuels.
- Air and Fuel Induction: This topic describes intake systems of engines, how air and fuel are delivered into the cylinders. Flow is modelled as quasi-steady state. The intake system consists of an intake manifold, a throttle, intake valves, and either a carburettor or fuel injectors.
- Combustion: This topic examines the combustion process that occurs in the combustion chamber of an engine. Simplified models are used to this complex phenomenon to correlate the operating parameters such as pressure, temperature, fuel, knock, engine speed, etc.
- Exhaust Flow: This topic describes the exhaust process that occurs in two steps, exhaust blow down followed by the exhaust stroke. The resulting flow out the exhaust pipe is modelled as pseudo-steady-state.
