Abstract
In a method for estimating an injected quantity of fuel of an isolated injection, the segment time of the cylinder in which the isolated injection takes place is evaluated numerically by forming the second temporal derivation. With the aid of the second temporal derivation of the segment time the injection parameters are updated using test quantity-test torque characteristic map.
