Abstract
Abstract 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 t o . Further, there is provided calculating means ( 83 a ), 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.
