    摘要： A diagnosis apparatus for diagnosing a catalystic converter of a motor vehicle as to whether the catalyst suffers deterioration by estimating a temperature of the catalyst or that of the exhaust gas in the vicinity of the catalyst on the basis of a plurality of engine parameters to thereby decide deterioration of the catalyst by using as an index the estimated temperature. The apparatus includes a unit for estimating the temperature of the catalyst in a steady state by making use of an engine speed and an engine load which represent typical parameters employed in fuel injection control of the engine. The steady-state temperature facility is realized by storing the engine speeds and the engine loads obtained experimentally in the steady state operation of the engine in the form of a two-dimensional data map. A unit for correcting the estimated temperature of the catalyst in the transient state is provided for correcting the catalyst temperature determined by the steady-state catalyst temperature estimating unit to thereby ensure correct estimation of the catalyst temperature even in the course of operation of the motor vehicle. In the transient temperature estimating unit, non-linear characteristics are each described by combining a plurality of linear characteristics. A unit for estimating the temperature of the catalyst on the basis of the value determined by the steady-state temperature estimating unit and the transient-state temperature estimating unit is provided to decide deterioration of the catalyst.

    摘要： A system and method for controlling ignition timing for an internal combustion engine to suppress engine knocking in which a periodic pseudo random signal (for example, M-series sequence signal) is superimposed on an ignition signal provided at an ignition timing, and a cross-correlation function between the periodic pseudo random signal .chi. and a knocking signal y is calculated to determine an actual knocking level. The ignition timing is then corrected so that the cross-correlation function coincides with a target value which is defined as a value placed in a vicinity of a knocking limit. The ignition timing for the engine is controlled so as to reach the value in the vicinity of the knocking limit but does not exceed the knocking limit.

    摘要： In order to prevent a catalyst for an internal combustion engine from decreasing efficiency by deterioration after long time use of the catalyst, the decreased efficiency of the catalyst is determined, and the internal engine is controlled based on results of the determination so as to maintain high efficiency of the catalyst. The catalyst is installed in an exhaust pipe of the engine. Sensors for detecting conditions of exhaust gas both at upstream side and downstream side of the catalyst are provided, respectively. As for the sensor, for example, an oxygen sensor of which output varies stepwise at &lgr;=1, or a sensor of which output varies in proportion to air-fuel ratio can be used. Detected values of the sensors are taken into a control unit, eliminating efficiency and deteriorating degree of the catalyst are estimated by comparison of the detected values, and the engine is controlled so that the eliminating efficiency becomes maximum. In accordance with the present invention, a preferable exhaust gas cleaning characteristics of the catalyst can be maintained because the decreased efficiency of the catalyst is determined exactly and the engine is controlled so as to prevent the catalyst from decreasing efficiency.
