Abstract

Industrial Research Limited has developed a remote sensing system with a rapid response time for measuring transient vehicle emissions. It has been used to evaluate vehicle performance over a standard urban driving cycle of about 7 minutes duration. During each driving cycle test, driving cycle activity was monitored by a chassis dynamometer, and over 400 emission readings were taken with the remote sensing equipment. Fuel consumption was also recorded. The transient emission readings could be correlated with specific driving activities, such as acceleration, idling and gear changing. The emission data could also be used to analyse the performance of different drivers.. It was apparent that different drivers with different techniques produced different emission profiles particularly durin
