Abstract
An internal combustion engine has a particle filter in an exhaust gas line for filtering solid particles contained in the exhaust gas, and includes a supplementary burner to which the solid particles are supplied from the filter and in which the particles are burned. The combustion gases from the supplementary burner are introduced into the air intake line for the engine, permitting a reduction in solid particles emitted into the environment when the NO.sub.x. content of the exhaust gases is reduced.
