Abstract

A reciprocating internal combustion engine with an emission control device and a method for operating same are described. At least one throttle, arranged on the intake side, at least one main fuel injection nozzle for feeding a main fuel to a combustion chamber of the diesel engine, and at least one catalytic converter are arranged in the center of an exhaust gas passage for conducting exhaust gas out of the combustion chamber, and at least one control device is used. A soot burn-off rate determined according to a model approach is maximized using a regulation process by means of a throttle valve.
