    摘要： A method and an apparatus for control of engine fuel injection are characterized by detecting the state of the acceleration of the engine and also judging whether or not the engine is in a specific acceleration state, by, when the engine is judged to be in a specific state of acceleration, using such a value as a crank angle obtained in advance in order to predict the air mass flow rate of the air flowing into a specific cylinder having undergone a fuel injection, by using the predicted air mass flow rate or the crank angle to determine a proper asynchronous fuel injection quantity for the above-mentioned acceleration state for the specific cylinder, and then by performing an asynchronous injection. Thus, they make it possible to calculate the shortage of fuel occurring with the synchronous injection even at the early stage of acceleration by using various variables so as to determine a proper supplemental fuel supply quantity (asynchronous injection quantity) for achieving a desired air fuel ratio in various drive modes.

    摘要： A method and a system for controlling fuel injection to an internal combustion engine (11) by electronic circuits (12-19). A plurality of cylinders (1-6) installed in the internal combustion engine (11) are divided into two groups and two electronic circuits (12, 13) for controlling the respective two cylinder groups (1, 3, 5,; 2, 4, 6) are provided. By comparing the outputs of the two electronic circuits (12, 13) whether the operations of the respective electronic circuits are normal or not is judged. The fuel injection controlled by the electronic circuit (12, 13) which has been judged to be abnormal is stopped, while the fuel injection controlled by the electronic circuit which has been judged to be normal is continued. Thus, the internal combustion engine is driven solely by one group of cylinders (1, 3, 5,; 2, 4, 6).

    摘要： A calculation unit (1) for calculating a gain matrix from process input and output information and a calculation unit (2) for calculating a parameter estimation have an independent weight setting unit (4). A weight W 1 (k + l) is set at a current time point while taking into consideration of an affect of square of residual e 2 (i) in each time step between an initial time step (i = l) to the current time step ( i = k + l), and a parameter is estimated in k+l accordance with an evaluation index J (k + l) = Σ W 1 (k + l). e 2 (i). i = I

    摘要： A novel engine control method is disclosed in which in order to dampen the longitudinal oscillation of a vehicle such as an automobile and to prevent the deterio­ration of the exhaust gas purification performance thereof, the longitudinal acceleration (α) or the engine speed (N) of the vehicle is detected, and the detected vehicle acceleration or engine speed, as the case may be, is differentiated. A signal with the phase of the differentiated value advanced by a specific value is produced and used to compensate for the fuel injection time (Ti) or a target value ( ϑ th ) of throttle opening degree.
