Internal Combustion Engines | ICE-2022 |

This course studies the fundamentals of how the design and operation of internal combustion engines affect their performance, efficiency, fuel requirements, and environmental impact. Topics include fluid flow, thermodynamics, combustion, heat transfer, friction phenomena, and fuel properties, with reference to engine power, efficiency, and emissions. Students examine the design features and operating characteristics of different types of internal combustion engines: spark-ignition, diesel, stratified-charge, and mixed-cycle enginesCOURSE OUTLINEFundamentals of Internal Combustion EnginesEngine & Heat EngineComparison of Internal and External combustion enginesPros and Cons of Internal Combustion enginesEngine classification.
