摘要：
An engine is fueled with a fuel blend of diesel and bidiesel fuel. A feed forward fuel control term is provided corresponding to a 100 percent diesel fuel blend and a feedback fuel control term corrects for lambda deviations resulting in a final fuel control term. During regeneration of a lean Nox trap, the feed forward fuel control term is adapted with a factor as a function of the feed forward fuel control term and the final fuel control term.
