PROBLEM TO BE SOLVED: To provide an engine generator including detection means capable of surely detecting the occurrence of fuel leakage while considering secular change of an engine.SOLUTION: The engine generator includes: a delivery flowmeter 31 for measuring a flow rate of a fuel passing a fuel delivery pipe 22; a return flowmeter 32 for measuring a flow rate of the fuel passing a fuel return pipe 23; electric power measuring means 33 for measuring electric power generated by a generator 12; and determination means 34 that compares a fuel supply amount to an engine, which is obtained by subtracting a measurement value of the return flowmeter from a measurement value of the delivery flowmeter, with engine fuel consumption calculated by a preset fuel consumption calculation expression on the basis of the generated electric power measured by the electric power measuring means, and determines the occurrence of fuel leakage when the fuel supply amount exceeds a preset amount for the fuel consumption,. The determination means includes fuel consumption calculation expression correction means 37 for correcting the fuel consumption calculation expression based on a use period of the engine. |
