ENGINE GOVERNOR

An engine governor (10) comprising a fuel supply calculation means for calculating the amount of fuel supplied to an engine (3) on the basis of the difference in speed between the target engine speed (Nset) and the actual engine speed (Nact), and a fuel supply adjustment means for adjusting the amount of fuel supplied to the engine (3) on the basis of the calculation results from the fuel supply calculation means, wherein in cases when the difference in speed between the target engine speed (Nset) and the 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 the target engine speed (Nset) is equal to or greater than a second predetermined speed, and the calculation results from the fuel supply calculation means 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 additionally in cases where the I component is a negative value, the I component is set to zero.
