In a method for controlling operations of a diesel engine according to the present invention, to control the number of rotations of the diesel engine using a water-emulsion fuel, a fuel injection amount is adjusted in accordance with a water addition ratio that is a ratio of water to a fuel. Especially, a required water addition ratio set in a water addition ratio setting device (11) to reduce a NOx concentration of an exhaust gas is limited by an calculating component (8) and the like in consideration of handling of the water-emulsion fuel, and the fuel injection amount is adjusted in accordance with the limited water addition ratio (x). |
