摘要： An air bypass valve failure detecting device outputs an opening command to an air bypass valve when a throttle valve suddenly closes, thereby prevent surging from occurring in a second intake passage between a turbocharger and a throttle valve. When the opening command is outputted to the air bypass valve, failure detection for the air bypass valve is permitted only if an intake air quantity of an engine immediately before a closing command is changed to the opening command is equal to or larger than a predetermined value. Thus, it is possible to prevent the failure detecting device from erroneously determining that the air bypass valve is normal although valve closing failure of the air bypass valve has occurred. This is because, when the intake air quantity is smaller than the predetermined value, surging does not occur in the second intake passage even if the valve closing failure of the airy bypass valve has occurred.
摘要翻译：当节气门突然闭合时，空气旁通阀故障检测装置向空气旁通阀输出打开命令，从而防止在涡轮增压器和节流阀之间的第二进气通道中发生喘振。当打开命令被输出到空气旁通阀时，只有紧接关闭命令之前的发动机的进气量改变为打开命令，才允许空气旁通阀的故障检测等于或大于预定值。因此，尽管发生了空气旁通阀的关闭故障，但是可以防止故障检测装置错误地确定空气旁通阀是正常的。这是因为，当进气量小于预定值时，即使发生通风旁通阀的关闭故障，也不会在第二进气通道中产生喘振。

摘要： When an engine load QC is equal to or larger than a predetermined value, an acceleration-state determiner determines that a turbine is in an acceleration state, and a supercharging-pressure-control-state determiner determines that supercharging-pressure controller (a bypass valve, a wastegate, and a variable flap) of a turbocharger are in a maximum supercharging pressure control state (a closed valve state), i.e., when a delay coefficient α of the turbocharger calculated by a delay-coefficient calculator on the basis of an actual supercharging pressure πc and a convergent value πc* of a supercharging pressure calculated by a convergent-value calculator indicates a value peculiar to the turbocharger, a failure of the supercharging-voltage controller is determined on the basis of the delay coefficient α. Thus, it is possible to secure a high failure detection accuracy, and increase a frequency of performing failure detection even when the engine load QC suddenly changes to cause a delay in a response of the supercharging pressure πc.

摘要： An abnormality determination device for an EGR device, which is capable of determining the abnormality of the EGR device properly without interrupting the EGR operation. An ECU of an internal combustion engine detects an amount of fresh air drawn into a combustion chamber of the engine, carries out feedback control of the fresh air amount such that the detected fresh air amount converges to a predetermined target fresh air amount by controlling an opening of a throttle valve disposed in an intake system of the engine during execution of EGR by the EGR device. The ECU obtains a decreasing degree parameter which represent a degree of decrease in the fresh air amount caused by the feedback control, and determines abnormality of the EGR device based on the obtained decreasing degree parameter.
