Abstract
At least one chemical heating measure, which causes an increase in the catalytic converter temperature essentially by introducing into the exhaust gas channel additional chemical energy in excess of energy provided at an initial engine operating point, is combined with at least one thermal heating measure, which causes an increase in the catalytic converter temperature essentially by introducing into the exhaust gas channel additional thermal energy in excess of energy provided at an initial engine operating point, so that a major fraction of the chemical energy is introduced temporally before a major fraction of the thermal energy is introduced.
