Abstract:
A method is provided for reducing emissions behind a catalytic converter in an exhaust gas stream of the engine. The method includes, but is not limited to controlling a power supply to a glowplug of a compression-ignition engine. The glowplug is activated if a set of at least two input values remains in a first characteristic region of an input parameter space for at least a predetermined activation time. The first characteristic region consists of one ore more contiguous regions of the input parameter space.
