Abstract
An engine governor calculates the amount of fuel supplied to an engine based on the difference in speed between the target engine speed (Nset) and actual engine speed (Nact). The amount of fuel supplied to the engine is adjusted based on the calculation results. When the difference in speed between the target engine speed (Nset) and low idle engine speed (Nlow) is equal to or less than a first predetermined speed, the difference in speed between the actual engine speed (Nact) and target engine speed (Nset) is equal to or greater than a second predetermined speed, and the calculation results are equal to or less than the minimum value of the actual engine speed (Nact), the P gain is set at a value equal to or greater than the normal value, and in cases where the I component is a negative value, the I component is set to zero.
