To set such that a determining portion determines whether fuel oil supplied to a diesel engine is first fuel oil (Bunker A, for example) or second fuel oil (Bunker C, for example), and appropriate water-emulsion fuel or fuel can be supplied to the diesel engine based on the result of the determination by the determining portion. A fuel supply apparatus (11) with a fuel switching function can switch a supply passage switching portion (20) such that one of first fuel oil and second fuel oil is supplied to a diesel engine (12), the first fuel oil and second fuel oil being used to produce water-emulsion fuel containing fuel oil and water or being used alone. A controller (28) includes the determining portion configured to determine whether the fuel oil supplied to the diesel engine (12) is the first fuel oil or the second fuel oil. Based on the result of the determination by the determining portion, the appropriate water-emulsion fuel or fuel can be supplied to the diesel engine (12). |
