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.]
