    摘要： An engine idle speed control device set a target idle speed NsetN for a non-traveling range is set to a high value to activate the catalytic converter early, after the engine is started. Upon detecting that the automatic transmission has been shifted from a non-traveling range to a traveling range, the target idle speed is lowered to a first traveling idle speed Nset1. A feedback gain G used for feedback control of the ignition timing is then set to a larger gain value. The larger gain value is set such that it varies based on the temperature of the automatic transmission fluid or other parameter indicative of the engine friction and/or automatic transmission friction. As a result, the ignition timing is retarded in a precise manner, the engine speed is reduced, and the clutch engagement shock is reduced.

    摘要： An engine idle speed control device set a target idle speed NsetN for a non-traveling range is set to a high value to activate the catalytic converter early, after the engine is started. Upon detecting that the automatic transmission has been shifted from a non-traveling range to a traveling range, the target idle speed is lowered to a first traveling idle speed Nset1 for a prescribed period (200 ms). After the prescribed period elapses, the target idle speed is lowered even further to a second traveling target idle speed Nset2. When the target idle speed is set to the first traveling target idle speed Nset1, the ignition timing retardation amount RET is set in accordance with the actual engine rotational speed Ne in such a fashion that the higher the engine rotational speed Ne is, the more the ignition timing ADV is retarded.

    摘要： An air-fuel ratio control apparatus is basically provided with an exhaust system, a first sensor and a controller. The exhaust system includes an exhaust channel with a main catalytic converter disposed therein, a bypass channel with a bypass catalytic converter disposed therein, and a valve mechanism disposed in the exhaust channel between the connection points of the exhaust channel to switch a pathway for exhaust gas from the exhaust channel to the bypass channel. The first sensor detects a property indicative of an air-fuel ratio of exhaust flowing in the exhaust channel at a point downstream of the valve mechanism. The controller adjusts an element temperature of the first sensor to a prescribed temperature or less during a prescribed interval of time from when the valve mechanism is switched from a closed state to an open state.

    摘要： A spark ignition internal combustion engine includes an exhaust gas reflux device capable of refluxing exhaust gas having passed through a catalyst for exhaust gas purification to an intake passage, an ignition timing control means for setting an ignition timing retard amount capable of preventing knocking according to a NOx concentration in the exhaust gas while the exhaust gas is refluxed, a NOx concentration estimation means for estimating the NOx concentration in the exhaust gas, and a purification performance reduction determination means for determining a reduction in purification performance of the catalyst. The ignition timing control means sets the ignition timing retard amount based on the NOx concentration in the exhaust gas before passage through the catalyst if the purification performance reduction determination means determines that the purification performance of the catalyst has been reduced to a state set in advance.

    摘要： An air-fuel ratio control device is provided for controlling the air-fuel ratio of an engine. The device includes an exhaust passage having a main catalytic converter and a bypass passage having a bypass catalytic converter, the bypass passage diverging from the exhaust passage at an upstream junction and rejoining the exhaust passage at a downstream junction. A valve mechanism disposed in the exhaust passage between the upstream junction and the downstream junction moves between a closed state and an open state. During a predetermined period of time after the valve mechanism opens to permit flow in the exhaust passage, the air-fuel ratio of the engine is controlled based on a signal from a first air-fuel ratio sensor in the bypass passage using a low response correction value that is less than a normal response correction value that would be used when the valve mechanism is closed.
