Course Learning Objectives:

 This course will provide a basic understanding of fuel properties and its measurements using various types of measuring devices
 Energy conversion principles, analysis and understanding of I C Engines will be discussed. Application of these concepts for these machines will be demonstrated. Performance analysis will be carried out using characteristic curves.
 Exhaust emissions of I C Engines will be measured and compared with the standards.
