摘要： A diagnosis device for a turbocharger, the diagnosis device includes an electronic control unit. The electronic control unit is configured to calculate a turbine expansion ratio as a ratio of a pressure of the exhaust gas flowing into a turbine of the turbocharger to the pressure of the exhaust gas flowing out from the turbine; operate a deterioration evaluation value toward a predetermined one of an increase side and a decrease side when the turbine expansion ratio exceeds a threshold; and determine a replacement timing of a turbine component when a total operation amount of the deterioration evaluation is equal to or larger than a specified value, the total operation amount being an operation amount from an initial value of the deterioration evaluation value.

摘要： A turbocharger-equipped internal combustion engine includes an exhaust turbine, an exhaust filter, a differential pressure detector, an atmospheric pressure sensor, and an electronic control unit. The electronic control unit is configured to control the internal combustion engine such that accumulation amount of a particulate matter in the exhaust filter is regulated. The electronic control unit is configured to control the internal combustion engine such that the accumulation amount of the particulate matter in the exhaust filter is increased, when the pressure difference detected by the differential pressure detector is a lower limit or less. The electronic control unit is configured to set the lower limit such that the lower limit becomes a higher value as the atmospheric pressure detected by the atmospheric pressure sensor becomes lower.
