Patent ID: 7797098

Claim:
An engine control device, in which a PTO device is connected to a vehicle engine and which controls a fuel injection quantity of said vehicle engine when the PTO device is in operation, comprising: PTO switching means for switching between operation and non-operation of said PTO device; and PTO fuel limiting means for limiting a fuel injection quantity of said vehicle engine to be less than a predetermined fuel limit value that is set in advance, when said PTO device is switched to an operational state by the PTO switching means, wherein said PTO fuel limiting means is configured to compensate said fuel limit value based on a coolant water temperature of said vehicle engine, and wherein the compensation based on said coolant water temperature is carried out such that the fuel limit value is raised as the coolant water temperature of said vehicle engine becomes lower when the coolant water temperature is less than a predetermined temperature, and the compensation is not carried out when the coolant water temperature is equal to or greater than the predetermined temperature.
