Abstract: A common rail fuel injection device for ensuring the main injection start timing by correcting a pulse start time of a main injection command pulse, in accordance with the length of an interval between the main injection and a pilot injection. The recovery degree of current energy for driving an injector varies in accordance with the length of the interval Tint from a pilot injection end (T4) to an main injection start time (T6), and this variation affects the main injection start time. By taking a longer value for an injector drive delay time (Td) as the length of the interval Tint is shorter, a pulse start time (T5) of a main injection command pulse CPm for performing the main injection is corrected as a more advanced timing, and hence the fuel injection for the main injection can be performed at a prescribed injection start timing.

Abstract: An engine fuel injection control device for improving stability of engine rotation after startup by determining a limited fuel injection amount for cold condition when the engine is insufficiently warmed-up, in addition to a limited fuel injection amount for normal operating condition. The limited fuel injection amount for normal operating condition Qlimo is calculated by a normal condition limited fuel injection amount calculating unit (42). The limited fuel injection amount for cold condition Qlimc is calculated by a cold condition limited fuel injection amount calculating unit (43) on the basis of engine rotational speed Ne. When a water temperature Tw is lower than a prescribed value Twd and a lapse time Trun after shifting from startup condition to normal operating condition is less than a prescribed time Trund, a limited fuel injection amount selecting unit (45) selects the larger of these values as a limited fuel injection amount Qlim.

Abstract: An engine fuel injection control device whereby appropriate engine output is obtained without generation of smoke, by determining a smoke limit fuel injection amount, using an inferred air intake amount when the engine operating condition is in a transient state etc. An inferred air intake amount calculation device (42) calculates an inferred air intake amount by using the target fuel injection amount on the previous occasion and the engine rotational speed. If the air amount deviation between the inferred air intake amount and the detected air intake amount detected by a mass airflow sensor (34) is more than a prescribed value, the detected air intake amount is deemed to be subject to detection lag. Then, the inferred air intake amount is selected as the final air intake amount, and the final fuel injection amount is calculated in accordance with this final air intake amount.

Abstract: A fuel injection control device of an engine having a plurality of cylinders, that prevents sudden change in combustion condition. The control device calculates a basic amount of fuel to be injected into cylinders. The controller then decides an amount of adjustment ultimately made to the basic amount of fuel based on an engine revolution speed difference between the cylinders. The adjustment is stepwise made to the basic amount of fuel so that a total amount of fuel gradually increases or decreases. Since a steep change does not occur in the total amount of fuel, the combustion condition does not change suddenly and the engine does not vibrate.

Abstract: 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.
