The regeneration of monolithic wall-flow diesel particulate traps

This thesis describes the behaviour of monolithic wall-flow diesel particulate traps during periodic cleaning or 'regeneration'. The concept and development of a new regeneration technique using low-power microwave energy is also presented. Health and environmental concerns with diesel engine particulate emissions have resulted in standards which will become increasingly strict during the 1990s. To meet these standards it is argued that diesel engines will require some form of exhaust after-treatment. [Continues.]
