摘要： A fuel injection control device includes an exhaust purification device for purifying an exhaust gas by catalytic action, an exhaust gas-temperature detection unit for detecting exhaust gas temperature, and a determination unit for determining the amount of the basic fuel injection and basic fuel injection timing from the operational status of a combustion engine, and a control unit for controlling the amount of the fuel injection and fuel injection timing. The control unit retards the fuel injection timing from the basic fuel injection timing when the exhaust gas temperature is lower than the temperature required for the catalytic activation of the exhaust purification device. The control unit also increases the amount of the fuel injection compared to the amount of the basic fuel injection to compensate for the loss of the torque output caused by the retarded fuel injection timing.

摘要： A fuel injection control device includes an after treatment device for purifying exhaust gas by the action of a catalyst, an exhaust gas temperature detector for detecting the exhaust gas temperature, and a controller for controlling the fuel injection quantity and fuel injection timing. The controller executes an exhaust gas temperature increase control by post-injection when the exhaust gas temperature detected by exhaust gas temperature detection means is less than the activity temperature of the catalyst in the after treatment device. When executing the exhaust gas temperature increase control, the controller determines the target injection quantity of post-injection based on the difference between the exhaust gas temperature considered as a target and the actual exhaust gas temperature detected by the exhaust gas temperature detector and also determines the upper limit value of injection quantity of post-injection based on the actual exhaust gas temperature detected by the exhaust gas temperature detector, conducts control such that the actual injection quantity of post-injection becomes the upper limit value when the target injection quantity is equal to the upper limit value or higher, and conducts control such that the actual injection quantity of post-injection becomes the target injection quantity when the target injection quantity is less than the upper limit value.

摘要： The detected values of a common rail pressure that were detected by a pressure sensor are read within crank angle periods Δt which are at least not more than half of a pumping cycle ΔT of a supply pump, the values detected within one pumping cycle preceding a reading time (for example, S(1), S(0), . . . S(−4)) are averaged during each of the reading times, and the value thus obtained (for example, Pav(1)) is used as a common rail pressure after averaging processing, which is a representative value or a control value of the actual common rail pressure. The feedback control of common rail pressure is executed by using the values of common rail pressure after averaging processing thus computed by moving averaging. Consequently, the actual common rail pressure is converted into values suitable for control, and the feedback control of common rail pressure is executed with higher accuracy.
