摘要： During deterioration detection of a catalyst, exhaust gas of a lean air/fuel ratio and exhaust gas of a rich air/fuel ratio are alternately supplied to the catalyst, and decrease of the O2 storage function is detected by obtaining the oxygen occlusion amount in the catalyst, based upon the timing at which, after changeover of the air/fuel ratio of the exhaust gas flowing into the catalyst, the air/fuel ratio of the exhaust gas passed through the catalyst changes to track that air/fuel ratio of the exhaust gas flowing into the catalyst. At this time, the rich air/fuel ratio of the exhaust gas and the lean air/fuel ratio of the exhaust gas supplied to the catalyst are set closer to the stoichiometric air/fuel ratio, the larger is the exhaust flow amount.

摘要： A catalyst protection device includes: a catalyst provided in an exhaust system of an internal combustion engine and purifying exhaust gas; a bed temperature acquisition unit acquiring a current bed temperature of the catalyst; a base increase value calculation unit calculating a base increase value that is a base value of an increase value of a fuel injection amount injected by a fuel injection valve included in the internal combustion engine in order to cool the catalyst when the current bed temperature exceeds a predetermined determination value; a compensator acquiring a corrected increase value by correcting the base increase value using a reduction coefficient that is calculated by incorporating a value of a target bed temperature set to a value strictly lower than the determination value; and an injection amount increasing unit selecting any one of the base increase value and the corrected increase value. When catalyst protection is required, the fuel increase value is therefore optimized to reasonable values, while not being reduced too much.

摘要： The valve timing is changed to increase the internal EGR amount the moment a fuel cut process begins (FIG. 2C). Before a sufficient amount of internal EGR is obtained, control is exercised so that the throttle-opening angle TA is larger than a basic idle-opening angle TA0. When a sufficient amount of internal EGR is obtained, control is exercised so that the throttle-opening angle TA is smaller than the basic idle-opening angle TA0 (FIG. 2D). The increase in the internal EGR amount is rendered smaller during fuel cut at a low rotation speed than during fuel cut at a high rotation speed. In addition, the amount of decrease in the throttle-opening angle TA is rendered smaller during fuel cut at a low rotation speed than during fuel cut at a high rotation speed.
摘要翻译：在燃料切断过程开始的时刻，气门正时被改变以增加内部EGR量（图2C）。在获得足够量的内部EGR之前，进行控制，使得节气门开启角度TA大于基本怠速开启角度TA 0。当获得足够量的内部EGR时，进行控制，使得节气门开度角TA小于基本怠速开启角度TA 0（图2D）。在低转速燃料切割期间，在高转速燃料切断期间，内部EGR量的增加变小。此外，与在高转速下的燃料切断期间相比，在低转速下的燃料切断期间，节气门开度角TA的减少量变小。

摘要： From the start of the engine to the detection of an engine speed peak, a control parameter (e.g., ignition timing) different from an air intake rate relating to an engine output is set to a value at which the engine output decreases than at an idling value. After detection of the peak, the control parameter is adjusted to the idling value.
