WORK MACHINE PROVIDED WITH ENGINE
Provided is a work machine (M) capable of detecting an abnormality in the amount of soot in exhaust gas in an exhaust pipe upstream of an exhaust gas aftertreatment device. The work machine (M) comprises: an exhaust gas sensor (14) which detects the amount of soot contained in exhaust gas (11g) between an engine (11) and an exhaust gas aftertreatment device (13) and generates a soot amount detection signal; and a controller (50) into which the detection signal is input. The controller (50) includes an abnormality judgment section that makes an abnormality judgment on whether or not the detected soot amount is abnormal, and a threshold setting section that sets a soot amount threshold that is a threshold for making the abnormality judgment. The abnormality judgment section is configured to judge an abnormality when the value of the soot amount corresponding to the soot amount detection signal is larger than the soot amount threshold.
