INTERNAL COMBUSTION ENGINE INSPECTION DEVICE
To provide an internal combustion engine inspection device capable of appropriately and more accurately detecting characteristic abnormalities of air flow rate detecting means of an industrial vehicle equipped with a hydraulic oil pump and an internal combustion engine driving the hydraulic oil pump.SOLUTION: An internal combustion engine inspection device which inspects air flow rate detecting means of an industrial vehicle equipped with a hydraulic oil pump and an internal combustion engine directly connected to the hydraulic oil pump without a clutch and driving the hydraulic oil pump, comprises: a rotation maintaining instruction unit that sends rotation maintaining request information to an internal combustion engine control unit; a load estimation unit that estimates the load of the internal combustion engine; a reference air flow rate calculation unit that calculates the reference air flow rate; an air flow rate read instruction unit that sends air flow rate read request information to the internal combustion engine control unit; an actual air flow rate acquisition unit that receives air flow rate read response information from the internal combustion engine control unit; and a characteristic determination unit that determines, on the basis of a flow rate deviation between the reference air flow rate and the detected air flow rate, whether the characteristics of the air flow rate detecting means are normal or abnormal.SELECTED DRAWING: Figure 4
