The IC Engine lab, which is a vital part of mechanical engineering curriculum, is intended to enble students to gain a deep understanding the working of IC engines by analyzing performance with thermodynamics principles. It contains fully functional and competent engines and other apparatus such as valve timing apparatus, port timing apparatus, calorimeters, flash and fire point apparatus, Orsat apparatus etc. With the help of single cylinder and multicylinder petrol and diesel engines the students will get an overall idea about their working and performance. By conducting heat balance test the students will get a clear concept of energy distribution occurring in an engine. The demonstrated cut section of four stroke and two stroke engines will help to know the basic functioning of an IC engine. To determine the properties of lubricating oil, flash and fire points test as well as Redwood Viscometer tests are also conducted. Orsat apparatus present in our lab helps in analyzing the pollution level of exhaust gas. We also have bomb as well as Junker’s calorimeters to find out the calorific values of solid, liquid and gaseous fuels.
