SECTION B

Introduction to emission

Pollutants, sources, formation of HC and CO in SI engines, NO formation in SI and CI engines,

Particulate emission from SI and CI engines, Smoke Emission in CI engines. Effect of operating

variables on Emission formation, Transient operational effects on pollution

SI Engine & CI Engines Combustion and Pollutant Formation

Basic Chemistry combustion - HC and CO formation in 4-stoke and 2-stroke SI engines - NO

formation, - Particulate emissions, - Effects of operating variables on emission formation.

Smoke emissions, Color and aldehyde emissions. Photochemical smog, Sulphur, Phosphorus

emissions,

Post Combustion Treatment

Introduction, physical conditions and exhaust gas compositions before treatment, catalytic

mechanism. Thermal reactions, installation of catalyst in exhaust lines, NOx treatment in diesel

engines. Diesel trap oxidizers

Control Techniques Engine Emission Reduction

Design changes - Optimization of operating factors - Exhaust gas recirculation - Fumigation - Air

injection PCV system - Exhaust treatment in SI engines - Thermal reactors - Catalytic converters

- Catalysts - Use of unleaded petrol.
