    摘要: A method for controlling a vehicle generator, by obtaining a first correction volume of an opening of an ISC valve (ISCPI) based on a deviation of a rotation number of an internal combustion engine from a target rotation number, obtaining a driving volume of an excitation coil of a generator based on a deviation of a battery voltage from a target voltage, and obtaining a second correction volume of an opening of the ISC valve (EL) that takes account of an electrical load variation based on a driving volume of the excitation coil and a rotation number of the internal combustion engine, to obtain a driving volume of the ISC valve (ISCDTY) based on the first and second correction volumes of the opening of the ISC valve.

    摘要: A system for purifying an exhaust gas for use in an automobile is disclosed which does not externally discharge unburnt hydrocarbons until a catalyst becomes active. An adsorbent is provided upstream of the catalyst. A heat exchanger is disposed between an upstream portion of the adsorbent and a portion between the adsorbent and the catalyst for controlling the elevation of the temperature of the adsorbent and for promoting the elevation of the temperature of the catalyst. The unburnt hydrocarbons are absorbed by the adsorbent in the initial period of time from starting of an engine until the catalyst becomes active. Temperature control is made in such a manner that the unburnt hydrocarbons which are adsorbed by the adsorbent begins to be desorbed therefrom substantially simultaneously with the time when the catalyst begins to function. A large quantity of unburnt hydrocarbons which are emitted from an engine immediately after the starting of the engine are prevented from being externally discharged without being treated.

    摘要: An engine knocking detection method for detecting a knocking from a plurality of characteristic frequency components indicative of a knocking condition is provided. False information indicating a false knock occurrence due to an abnormal drop of the background level to be compared with the characteristic components is eliminated. Information indicating an occurrence of a knocking is extracted through comparison of the characteristic components and corresponding background levels. The background levels are compared with corresponding lower limiters when no knocking is taking place. When any one of the background levels is smaller than a lower limiter corresponding thereto, the lower limiter is adopted and set as a new background levels drops abnormally, a corresponding lower limiter thereof is effected to replace the faulty background level, thereby false information indicating the occurrence of a false knocking is prevented from being generated.

    摘要: A catalyst heating control device for cleaning automotive engine exhaust gases, comprising a generator, at least one battery, a catalyst heating control apparatus, a battery charging device and an electronic fuel injector. Before starting the engine, the catalyst is preheated. At the start of the engine, the catalyst preheat control is curtailed according to the state of the batteries. The catalyst current control is performed by detecting the catalyst activation temperature. The catalyst is heated usually to about 350.degree. C., at which point the current supply for heating is terminated.
