    摘要: This anomaly determination system is provided with an inlet pressure sensor (31) which detects the inlet pressure of a pressure loss unit (26) provided in the fluid passage (25) in a vehicle, an outlet pressure sensor (32) which detects the outlet pressure of the pressure loss unit (26), an atmospheric pressure sensor (33) which detects the atmospheric pressure, which is the pressure outside of the fluid passage (25), and an anomaly determination unit (35) which determines anomalies in the pressure loss unit (26). The anomaly determination unit (35) determines that there is an anomaly in the pressure loss unit (26) if the difference between the inlet and outlet pressure, the difference between the outlet and atmospheric pressure, and the difference between the outside and inlet pressure, detected when the flow rate in the fluid passage (25) is less than the minimum flow rate at which anomalies in the pressure loss unit (26) are detectable, are within an allowable range, and the pressure difference between the inlet pressure and outlet pressure when the flow rate is greater than or equal to the minimum flow rate is within a first pressure loss range.

    摘要: A fault detection device includes a wastegate valve (23), a control unit (31), a working gas amount computation section (35), and a determination section (38). The control unit (31) obtains a rotational speed (NE) of an engine (10), a boost pressure (Pb), and an intake air i temperature (Tin). The working gas amount computation section (35) computes a computed value (Gc) of a mass flow rate of working gas in the engine (10) by using the rotational speed (NE), the boost pressure (Pb), and the intake air temperature (Tin). The determination section (38) determines that the wastegate valve (38) has a fault when the computed value (Gc) is not a normal value (Gs).

    摘要: Based on entry/exit pressures of compressor 2a detected by atmospheric/boost pressure sensors 13 and 14, pressure ratio of compressor is calculated. Based on mass flow rate and entry temperature of intake air 4 detected by intake air flow-rate/temperature sensors 15 and 16 and entry pressure, volumetric flow rate of intake air is calculated in environmental condition at detection time using gas state equation, and is corrected into volumetric flow rate under standard environmental condition thorough multiplication by corrective coefficient based on entry temperature of intake air. Based on corrected value and calculated pressure ratio, rotational frequency of compressor under standard environmental condition is read out in light of operating characteristic diagram for compressor. Read-out rotational frequency is corrected into actual rotational frequency of compressor through multiplication by corrective coefficient based on entry temperature of intake air, which is determined as rotational frequency of turbocharger 2.
