Fuels – types and properties-higher and lower heating values, their determination. Combustion of fuels, stoichiometric air requirement – excess air-gravimetric analysis and volumetric analysis of products of combustion and their conversions-Fuels for IC engines- octane number requirement (ONR)-diesel fuels cetane rating.

Classification-engine components-Four stroke cycle- principle-valve timing diagram-P-V diagram - two stroke cycle- principle-valve timing diagram-P-V diagram. Spark ignition engine-working principle and thermal efficiency- Compression ignition engine-working principle and thermal efficiency-fuel pump and injector. Gas engine –working principle-turbo charging.

Carburetion-Fuel injection-Ignition- Engine friction and Lubrication- Engine cooling-Scavenging in two stroke engines- Super changing of SI engines- Comparison between CI and SI engines.

Engine Testing and performance- Dynamometer types- Performance parameters - Indicated power, Brake power, SFC, Engine efficiencies- Variables affecting performance characteristics- Working principles of Stirling engines, Wankel rotary combustion engine, Variable compression ratio engine test rig- Emission standards. Air compressors- Reciprocating, Rotary and Centrifugal types- Work done and Efficiency-Slip factor.
