The present invention provides a packaged engine working machine adapted so that an electrical component containing space for containing electrical components is partitioned into two spaces but a cooling air intake port is provided at a single position in a concentrated manner. In a packaged engine working machine 1 in which an engine 5 is disposed in a lower space 4 of a package 2 and electrical components are disposed in an upper space 3 thereof, the upper space is partitioned into: a high heat generation chamber 33 in which high heat generation components are disposed; a low heat generation chamber 34 in which low heat generation components are disposed; and an intake fan chamber 35 provided with an intake fan 36 for sucking outside air through a single intake port 39d. The packaged engine working machine includes a high heat generation chamber cooling path Q through which outside air F from the intake port reaches the intake fan chamber via the high heat generation chamber and the first communication port 74; and a low heat generation chamber cooling path R through which the outside air from the intake port reaches the intake fan chamber via the high heat generation chamber, the second communication port 75, the low heat generation chamber and the third communication port 76. |
