本発明による方法の更に有利な変更態様および形態が得られる。
必要な燃料の配量数量は、必要な温度上昇、燃料の発熱量、排気ガス質量流量に対する尺度、排気ガス質量流量の比熱容量から、並びにモデルにより計算可能である。
空気センサ12は制御装置31に空気信号mslを出力し、内燃機関10は回転速度Nを出力し、第1の排気温度センサ22は第1の排気実際温度TabgvKを出力し、第2の排気温度センサ24は第2の排気実際温度TabgvPFを出力する。制御装置31にはトルク目標信号Mfaが供給される。
制御装置31は、はじめに、例えば図示されていない自動車の加速ペダルの位置の関数であるトルク目標値Mfaの関数として、燃料信号mEを決定する。燃料信号mEは、内燃機関10の燃料供給装置30に、少なくとも1つの所定の時点において所定の燃料量を供給するように指示する。燃料信号mEの決定において、制御装置31は、場合によりさらに、空気センサ12から供給される空気信号mslおよび/または内燃機関10から供給される回転速度Nを考慮してもよい。
