STUDY OF EFFECT OF SPEED, ACCELERATION AND DECELERATION OF SMALL PETROL CAR ON ITS TAIL PIPE EMISSION

摘要: Pollution from vehicles is due to discharges like Carbon monoxide (CO), dioxide (CO 2 ), Hydrocarbon (HC) and Oxides of Nitrogen (NOx) through their tailpipe. Cars, being in dominant proportions (36.5%) Indian traffic stream with small cars above 50% total car proportions, are the main contributors pollutants. Literature reveals that all factors constant, at signalized intersection, emission rates function speed acceleration. Since it difficult collect position data actual this study conducted on link road between National Highway 31 IIT Guwahati, India, replicating queue leader intersection. Tailpipe emissions measured using onboard measurement system GPS device. Study illustrates tailpipe CO, HC NOx sensitive vehicle similar acceleration level. rate initially decreases increase then afterwards further speed, Emission found rate. It was observed deceleration does not influence cars.
