The paper describes a programme of work carried out on a swirling direct injection diesel combustion system to establish the relative contribution of fuel burning from fully evaporated, droplet and 'off the wall' conditions to particulate formation and emissions. The high speed combustion photography and in-cylinder sampling techniques which were used are described. Results which enabled the formation and subsequent decay of particulate matter during the combustion process to be quantified are presented. Since the time in the 1970's when concern arose over the potentially harmful effects of particulate emissions from diesel engines numerous investigations have been carried out to establish the factors that cause particulate matter to be formed and the most effective method of control. One of the programmes carried out by Ricardo Consulting Engineers plc has studied in detail the particulate emissions from heavy duty (truck size) diesel engines. The programme which was sponsored by a Consortium of UK organizations including the UK Department of Industry, various engine, and component, manufacturers and petroleum.
