    摘要： This control apparatus obtains a relation (trade-off line) between NOx generation amount and PM generation amount with EGR ratio serving as a parameter from an NOx generation amount estimation model which calculates the NOx generation amount on the basis of the oxygen mole concentration of intake gas and a PM generation amount estimation model which calculates the PM generation amount on the basis of an excess air factor. Further, the control apparatus obtains a straight line (ratio determination line) which passes through a point (appropriate point A) corresponding to a combination of steady-condition appropriate values of the NOx generation amount and the PM generation amount under the present operating conditions and which has a slope K determined in consideration of a regulation value based on a law relating to emission control. The control apparatus uses an intersection (target point B) between the trade-off line and the ratio determination line as an emission target value, and sets an EGR ratio target value Regrt to an EGR ratio corresponding to the target point B.

    摘要： A soot generation amount estimation apparatus obtains a generation speed of a precursor of soot (accordingly, the concentration of the precursor) in consideration of formation of the precursor from fuel, thermal decomposition of the formed precursor, and formation of soot from the formed precursor, and estimates a generation speed of soot (accordingly, the concentration of soot (the generation amount of soot)) in consideration of formation of soot from the precursor, which depends on the concentration of the precursor, and oxidation of the formed soot. The apparatus employs a reaction model in which the reaction process in which soot is generated from fuel is divided into two steps; i.e., a reaction process in which a precursor is generated from fuel and a reaction process in which soot is generated from the precursor. Thus, phenomena, such as a “delay in soot generation” in the reaction process in which soot is generated from fuel, can be accurately simulated.

    摘要： The fuel injection control device includes an electronic control unit (ECU) for controlling a fuel injection amount of the diesel engine of an automobile. The ECU determines a basic fuel injection amount in accordance with the engine operating condition such as the amount of depression of the accelerator pedal, the intake air amount and the engine speed. Further, the ECU estimates the magnitude of the torsional vibration of the output shaft system of the engine when the basic fuel injection amount of fuel is supplied to the engine using a model of the output shaft system. The ECU performs a feedforward control based on the estimated magnitude of the torsional vibration and corrects the basic fuel injection amount so that the torsional vibration becomes small. Therefore, the fuel injection amount is corrected to attenuate the torsional vibration before the torsional vibration actually occurs.

    摘要： A control apparatus for an internal combustion engine with an exhaust gas recirculation system is disclosed. The control apparatus grasps an optimum relational expression between an excess air ratio and an EGR rate in a transient engine operating condition changing to a certain engine operating condition. Each combination of the excess air ratio and the EGR rate on the relational expression optimizes an amount of generated paticulates and an amount of generated NO.sub.x. The relational expression contains a combination of an optimum excess air ratio and an optimum EGR rate in the certain engine operating condition. The apparatus determines one of a current excess air ratio and a current EGR rate and controls the exhaust gas recirculation system so as to realize the other of an excess air ratio and an EGR rate satisfying the relational expression with respect to one of the current excess air ratio and the current EGR rate.
