.
Course Objectives:
The objective is to introduce some of the components mainly used in IC Engines and make analysis of various forces involved. Subjects deals with topics like inertia forces in slider crank mechanism; IC Engine components and the analysis like governors is introduced. It also deals with balancing of rotating and reciprocating parts. Studies are made about balancing of multi cylinder engines, Radial engines etc. study of primary and secondary forces are considered while balancing. Finally they are introduced to the topic of vibrations. The study deals with linear, longitudinal, and torsional vibrations. The idea is to introduce the concept of natural frequency and the importance of resonance and critical speeds.
Course Outcomes:
the study of KOM and DOM are necessary to have an idea while designing the various machine members like shafts, bearings, gears, belts and chains and various I.C. Engine Components and Machine tool parts.
