Pulling together a wealth of knowledge that is currently disseminated throughout journal and conference papers, this book addresses a field of increased international interest and research activity as well as legislation. Authored by an acknowledged expert in the field it discusses the impact of new legislation on the automotive industry, and new ways of measuring particulate size, number and composition that are now being sought. The book is divided into sections on particulate fundamentals, formation, characterisation, measurement, abatement, and health; and also inlcudes chapters on spark-ignition engines and processes of disintegration.
