Spark Ignition engines: Mixture requirement – Feedback control carburettors – Fuel injection systems. Stochiometric combustion – combustion with excess airequivalence ratio.
Stages of combustion: Normal and Abnormal combustion – Knock Combustion chambers. Simple thermodynamic analysis of SI engine combustion.
Compression ignition engines: Nature of combustion in IC engines – Direct and Indirect injection systems – Air motion – Combustion Chambers – Spray penetration and evaporation. Supercharging – Turbo charging. Thermodynamic analysis of CI engine combustion. Wankel Engine: Operation & applications. Hybrid vehicles.
Thermo chemistry: Pollutant formation, Instrumentation to measure pollutants – Pollutant calculation – Effect of air-fuel ratio.
