摘要： The present invention relates to a diagnosis apparatus which can plan a maintenance plan, a renewal plan, and the like of a self-propelled vehicle, by detecting a work load in addition to an engine condition. Accordingly, there is provided: engine rotating speed detecting means (11), for detecting a rotating speed N of the engine; fuel injection amount detecting means, for detecting a fuel injection amount q per rotation of the engine; loaded weight detecting means, for detecting the weight W of the loaded material; vehicle speed detecting means (14), for detecting the vehicle speed V; and trigger signal oscillating means (82), for oscillating a trigger signal d per predetermined time period to. Further, there is provided calculating means (83a), which receives each of the signals, which calculates a time period t for which both the rotating speed N having substantially the same value and the fuel injection amount q substantially the same value are maintained on the basis of the number n of the trigger signal d, which calculates an accumulative total fuel injection amount Q, and which successively calculates at least one of a fuel injection amount q1 per unit time and a conveying amount w1 per unit fuel injection amount.

摘要： It is possible to prevent generation of failure in a dump truck and to diagnose a true cause of failure in a short period of time. Thus the present failure diagnosis method diagnoses an operation and function of at least one of respective devices, such as an engine at a predetermined engine rotational speed, a transmission, respective axles, respective suspensions, hydro-pneumatic systems, and a brake while a vessel body (4) descends after evacuation of a load. The failure diagnosis device comprises body operating means (50) for raising or lowering a vessel body, a direction switching valve (7) for receiving a command from the body operating means to lower the vessel body, and a self-diagnosis control device (11) for using state detecting means (20) to detect and store a state of at least one of the respective devices at a predetermined engine rotational speed when the body operating means is at a predetermined operative position and for comparing a magnitude of a detected value and a rate of change with reference values on the basis of hysteresis data when carrying out failure diagnosis.
