AM4201 Automotive Pollution and Control Syllabus:
AM4201 Automotive Pollution and Control Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To discuss the harmful effects of major pollutants on living beings and the environment
To analyse the formation of major pollutants like UBHC, CO, NOx, particulate matter and smoke.
To design various control techniques to reduce pollutants in combustion
To determine the various after treatment process to minimize emissions
To demonstrate the various devices used to measure pollutants and discuss the Emission standards followed in various nations
UNIT I EMISSIONS FROM AUTOMOBILES
Sources of Pollution. Various emissions from Automobiles — Formation — Effects of pollutants on environment human beings. Emission control techniques – Emission standards.
UNIT II EMISSIONS FROM SPARK IGNITION ENGINE AND ITS CONTROL
Emission formation in SI Engines- Carbon monoxide- Unburned hydrocarbon, NOx, Smoke —Effects of design and operating variables on emission formation – controlling of pollutants -Catalytic converters — Charcoal Canister — Positive Crank case ventilation system, Secondary air injection, thermal reactor, Laser Assisted Combustion.
UNIT III EMISSIONS FROM COMPRESSION IGNITION ENGINE AND ITS CONTROL
Formation of White, Blue, and Black Smokes, NOx, soot, Sulphur particulate and Intermediate Compounds – Physical and Chemical delay — Significance Effect of Operating variables on Emission formation — Fumigation, EGR, HCCI, Particulate Traps, SCR — Cetane number Effect.
UNIT IV NOISE POLLUTION FROM AUTOMOBILES
Sources of Noise — Engine Noise, Transmission Noise, vehicle structural Noise, aerodynamics noise, Exhaust Noise. Noise reduction in Automobiles — Encapsulation technique for noise reduction — Silencer Design
