Abstract
In a method for exhaust-gas treatment for diesel engines, the exhaust gas is conducted through a regenerable particulate filter as well as an NOx catalytic converter, each disposed in exhaust branch. The exhaust gas is first conducted through the NOx catalytic converter of the carbamide SCR type situated close to the engine, and subsequently through the particulate filter of the CSF type, the energy necessary for regenerating the particulate filter being supplied to it from outside. Fuel is used as regenerating agent, which is taken from fuel tank provided for the operation of the diesel engine.
