摘要： A first catalyst 21 which stores or releases oxygen according to an air-fuel ratio, and a second catalyst 22 which traps or releases NOx according to the air-fuel ratio, are provided in an exhaust passage 9 of an engine 1. A controller 6 temporarily shifts the air-fuel ratio of the engine 1 to rich when it is determined that the NOx trap catalyst second catalyst 22 is released. At this time, the controller 6 increases a reducing agent supply amount due to the rich shift to be larger, the larger the oxygen amount stored by the two catalysts 21, 22. In this way, the air-fuel ratio in the second catalyst 22 is maintained at a target stoichiometric or rich air-fuel ratio.

摘要： A camshaft rotational phase detecting apparatus for an engine provided with a variable valve timing control mechanism which controls a camshaft rotational phase of an engine valve to a target camshaft rotational phase by varying a rotational phase of a camshaft relative to a crankshaft. The camshaft rotational phase detecting apparatus is configured to detect a camshaft rotational phase as a detected camshaft rotational phase based on a signal from a sensor. In the apparatus, the detected camshaft rotational phase is substituted with a maintained rotational phase for a predetermined period and is substituted with a target camshaft rotational phase after a lapse of the predetermined period, when the camshaft rotational phase is not detected. In the apparatus, the maintained rotational phase is set corresponding to the detected camshaft rotational phase detected before a timing that the camshaft rotational phase is not detected. Additionally, in the apparatus, the predetermined period is set in accordance with an engine temperature.

摘要： An apparatus for use with an internal combustion engine having a fuel vapor trap from which fuel vapor is purged into the engine through a purge passage having a purge control valve provided therein. The purge control valve is controlled to permit fuel vapor purge through the purge passage based on the existing engine operating conditions. An air/fuel ratio feedback control correction factor is calculated to correct the air/fuel ratio within a predetermined range based on the air/fuel ratio of the mixture supplied to the engine. A gain value is calculated based on a deviation between the air/fuel ratio feedback correction factor calculated with the fuel vapor purge and the air/fuel ratio feedback correction factor calculated without the fuel vapor purge and a purge rate of the fuel vapor flow rate to the intake air flow rate. The calculated gain values are stored in a memory in respective memory locations addressable by different fuel vapor amounts. The calculated gain value is stored in the memory in a memory location corresponding to the sensed fuel vapor amount to update a gain value stored previously in the memory location. A gain value is read from the memory location corresponding to the fuel vapor amount. The amount of fuel supplied to the engine is controlled according to a target value calculated based on the read gain value and the engine operating conditions.

摘要： The present invention enables a decrease in etching velocity in an ion-beam etching system without decreasing the current density of the ion beam. The ion-etching is performed at a constant value of ion-beam current density and an increased partial pressure of oxygen or other suitable gas in the specimen chamber. The partial pressure of oxygen is increased until the intensity of a secondary ion-beam from the specimen reaches a saturation value. Under these conditions a stable reduced etching velocity is obtained, the value of which is determined by the ion-beam current density, the partial pressure of oxygen and the previously determined characteristics of the specimen.

摘要： A stream of pulses related to rotation rate drives an interrupt to store first timer values of a first timer and to set a second timer to run from zero. At predetermined fixed time intervals, second timer values of the second timer are stored. The stored first timer values are sampled to determine a first rate related to the input stream. The stored second timer values are sampled to determine a second rate. The first and second rates are selectively used as a final rotation rate related to the input stream.
