The invention relates to a method for controlling an internal combustion
engine with a fuel injection system which can comprise, in addition to a
main injection quantity, an additional amount of pre-injected and/or
post-injected fuel for each injection pulse for each combustion chamber
for each combustion cycle at a given injection time. A theoretical torque
is determined from an accelerator pedal value, rotational speed and air or
fuel mass flow while taking into account a factor from a family of
characteristics. According to the invention, the calculated theoretical
torque is corrected in the case of a pre-injected or post-injected fuel
mass flow by taking into account, in a correction factor, a value for a
time or phase difference of the amount of pre-injected or post-injected
fuel and the main injection quantity for each cycle.
