On Board Exhaust Emission Monitoring of Road Vehicles - A High Tech Solution to Pollution from Traffic?

Abstract

This legislation and similar ones in other global regions have helped to greatly reduce emission levels from road transport. However, a massive increase in the number of cars on the road have meant that pollution due to a number of gases and particulate species remains to be a problem. This paper describes an approach based on optical fibre sensors which has shown to be an effective means of measuring the gases and particulates in question by using sensing technologies which are both robust and potentially cost effective such that they may be included as part of an on board monitoring system for the car of the future.

Towards a New Gas Sensor Microsystem Using Electroactive Polymers Thin Films

“…In industrialized countries, the growth of production and traffic contribute to the degradation of air quality [19,20]. In relation with an increasing interest for environmental questions all over the world, the demand of new measurements increases.…”

Portable infrared carbon dioxide detector for monitoring vehicular emissions

“…So it becomes imperative to monitor the CO 2 level from vehicle emissions. Hence, in recent years, there has been an increasing interest in developing onboard CO 2 emission monitoring system for vehicles to address the CO 2 related pollution problems [2], [3].…”
