AU3601 Automotive Pollution and Control Syllabus:
AU3601 Automotive Pollution and Control Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
The objective of this course is to prepare the students to have knowledge on the harmful effects of major pollutants of IC engines, emission standards, various pollution measurement devices and control techniques
UNIT I EMISSION FROM AUTOMOBILES
Sources of Pollution. Various emissions from Automobiles — Formation — Effects of pollutants on environment human beings. Emission control techniques – Emission standards – National and international.
UNIT II EMISSION 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 EMISSION 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.
UNIT V TEST PROCEDURES AND EMISSION MEASUREMENTS
Constant Volume Sampling I and 3 (CVSI & CVS3) Systems- Sampling Procedures — Chassis dyno – Seven mode and thirteen mode cycles for Emission Sampling — Sampling problems — world harmonized driving cycles – Emission analysers —NDIR, FID, Chemiluminesecent, Smoke meters, Dilution Tunnel, SHED Test, Sound level meters. Particle counter
TOTAL: 45 PERIODS
