COURSE OBJECTIVES

The course provides introductory overview of spark ignition and compression ignition engines. Describes combustion chemistry, and identifies the parameters and engine operations to develop understanding of the thermodynamics and combustion process for a quantitative analysis of internal combustion engines. Detail of gas exchange and inflow and outflow of gases explained. Engine classification, engine cycle, combustion processes, reaction of engine fuels, release of energy and ultimate conversion into useful work is illustrated. A concise discussion on topics like performance of engines, Knocking, Octane number, Cetane number, engine valve timing, ignition advance/ retard, and working principle of turbo-charged engine is also included. Highlighting that Internal Combustion Engines are a source of pollution and controlling the emissions is emphasized.
