Abstract: 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.

Abstract: A catalyst deterioration determination device capable of determining whether or not fuel is high-sulfur fuel containing much sulfur content, and properly determining whether a catalyst is deteriorated while suppressing the frequency of execution of control for recovering the catalyst from the poisoned state to the minimum. The device determines whether or not a catalyst which purifies exhaust gases exhausted from an internal combustion engine is deteriorated based on the capacity of the catalyst for purifying exhaust gases. If it is determined that the catalyst is deteriorated, first sulfur elimination control is executed for eliminating sulfur content accumulated in the catalyst. Further, when the first sulfur elimination control is terminated, the deterioration determination of the catalyst is executed. Then, when it is determined by the deterioration determination that the catalyst is not deteriorated, it is determined that the fuel is high-sulfur fuel containing lots of sulfur content.

Abstract: 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.
