<p>PROBLEM TO BE SOLVED: To provide an engine-drive work machine which can satisfactorily supply raw water from a raw water tank into an evaporator by a simple configuration.SOLUTION: An engine-drive work machine 10 includes an evaporator 35 which evaporates raw water 29 by waste heat. The evaporator 35 includes a raw water intake part 63 which communicates with a raw water tank 41, and an air vent part 64 which communicates with the raw water tank 41. The raw water tank 41 includes a tank container 94 which has a water supply port 95, a water supply cap 96 which opens and closes the water supply port 95, and an opening and closing switching valve 98 which is in conjunction with opening and closing operation of the water supply cap 96. The opening and closing switching valve 98 is configured so that the raw water intake part 63 and the tank container 94 are maintained in a non-communicated state when the water supply port 95 is opened, and so that the raw water intake part 63 and the tank container 94 are maintained in a communicated state when the water supply port 95 is closed.</p> |
