Abstract
Several studies, in the past, have used chassis dynamometer and remote-sensing method to describe effects of speeds on pollutant emissions. These studies reasonably lacked data on important modal events such as acceleration, deceleration, speed, and their effects on emissions. Present study includes on-road experiments carried out to examine the impacts of car speed, acceleration, and deceleration on their tailpipe emissions. The study was carried out on cars, with and without catalytic converter on a two-lane roadway in engine operating modes of acceleration and deceleration. The power to weight ratio of the cars was 0.03hp/lb. The relationships of pollutant emissions with the speeds were examined at two acceleration levels (a ≈ 1.0 m/s2 and a ≈ 1.6 m/s2). A prominent relationship of tailpipe emission with the averaged speed was seen at both accelerations. Further, the pollutant emissions were different at different speed ranges of 0-3 m/s (0-10.8 km/h), 3-6 m/s (10.8-21.6 km/h) and above 6 m/s (21.6 km/h). A second-order statistical emission - speed model has been presented and discussed. The effect of deceleration on tailpipe emission was not clear in the study.
