Thermal Lab

The purpose of thermal engineering laboratory is to give conceptual and principles involving in thermal science, especially focusing on Internal Combustion Engine, Steam Generators and Compressors. The mobility sector utilizes IC combustion engine which serves as the heart of automobile industry. The study of IC engines is vital for any mechanical engineer. Students will learn about the measurement of performance, retardation, heat balance, frictional power, etc. Study and testing of various oil properties for using as a fuel and lubricant in internal combustion engine and thermal systems.
