Abstract
When an internal combustion engine that is provided in a work machine and that serves as a power source for the work machine is controlled, the following lines are used: a first equal throttle line which is defined to correspond to a case where an amount of fuel injection for the internal combustion engine is maximum where the rotation speed of the internal combustion engine is the same and so that an output of the internal combustion engine becomes constant, a second equal throttle line which is defined to correspond to a case where the amount of fuel injection for the internal combustion engine is zero where the rotation speed of the internal combustion engine is the same and so that the torque decreases with increase of the rotation speed, and a third equal throttle line which is obtained from the first equal throttle line and the second equal throttle line.
