Abstract

A method and an apparatus reduces particles in exhaust gases of an internal combustion engine by passing the exhaust gases through a microwave energy field in a resonator for applying energy and burning the particles. In order to improve the application of energy, the particles are agglomerated beforehand in a high-voltage field of an electrostatic filter.
