ENGINE POWERED MACHINE

摘要

[PROBLEMS]An engine powered machine having an exhaust purification device that is of low cost and in which a reducing agent is not overheated.[MEANS FOR SOLVING PROBLEMS]The engine powered machine has the exhaust purification device in which the reducing agent is injected by a reducing agent supply device (4) into an exhaust pipe (2) of an engine (1) to render nitrogen oxides in exhaust gas harmless. The engine powered machine further has a cooling fan (7) as a cooling device for cooling a reducing agent tank (5) for containing the reducing agent injected by the reducing agent supply device (4), and the drive and stop of the cooling fan (7) are controlled by a controller (12). The controller (12) drives the cooling fan (7) to start to cool the reducing agent tank (5) when a detection temperature signal (a) outputted from a reducing agent temperature detector (6) becomes higher than a cooling start temperature stored in a storage section (12b).
