Abstract
With a lifetime of 15 years and more, many vehicles on the European roads no longer have to satisfy durability and in-service conformity requirements. If new cars satisfy stringent on-road emission standard, the risk of significant increase in emissions due to aging, malfunctions, poor maintenance and tampering will be substantial. Even a few percent failure average emissions could increase by a factor two or more. In the Netherlands this issue is investigated and a number of problems have been identified. Currently, the impact for air-quality is investigated, as are the options to stem the increase in emissions with age. Specifically, the failure and removal of diesel particulate filters and unnoticed malfunctions of the three-way catalyst system are investigated. Furthermore, options to address such problems are studied.
