Abstract (en)
[origin: DE4444416A1] In a fuel dosage control process for internal combustion engines, in particular in an unsteady mode of operation, a correction signal (fTW, kTW) is generated to control fuel dosage. For that purpose, at least one of the following signals is taken into account: a signal (QK) related to the heat flow caused by fuel evaporation in the suction pipe (102); a signal (QAn) related to the heat flow between the air that flows through the suction pipe (102) and the wall of the suction pipe (102); a signal (QMot) related to the heat flow between the engine block and the wall of the suction pipe (102); a signal (QU) related to the heat flow between the air flowing through the engine chamber and the wall of the suction pipe (102). A signal (TW) that represents the temperature of the wall of the suction pipe (102) may be determined when forming the correction signal (fTW, kTW).
