摘要： An engine control unit (ECU) monitors an idling rotation speed of a diesel engine and predicts a tendency of an increase in an injection quantity occurring until an increasing rate of the injection quantity converges based on an initial tendency of an increase in the idling rotation speed. If the idling rotation speed exceeds a predetermined reference rotation speed, the ECU performs correction (counter control) for reducing the injection quantity. Thus, an increase in the injection quantity due to changes in hardware with time can be eluded, and an increase in an engine output due to the increase in the injection quantity can be inhibited. Therefore, damages to the diesel engine due to an excessive increase in the engine output can be prevented.

摘要： At abnormal pressure pulsation generating time, a piston of a pulsation reducing apparatus is displaced in a valve chamber due to an increase in a fuel pressure in an upstream side fuel passage, so that fluid communication between a valve chamber and a downstream side fuel passage is disabled, and fluid communication between a valve chamber side end part of a return passage and the valve chamber is enabled. Pressure pulsation is conducted into the return passage and is reduced by a damping effect of a pulsation reducing mechanism and a flow restricting effect of orifices. The fuel, which has passed through the orifices, is returned to the upstream side fuel passage through the return passage.

摘要： A fuel injection controller of a diesel engine calculates a requirement injection amount based on an operation amount of an accelerator pedal and rotation speed of the engine. The fuel injection controller divides the requirement injection amount into multiple injections. Injection amounts of the divided injections are set to monotonically increase with respect to an order of the injections. Thus, even if a simple fuel injection device is used, the fuel injection controller can suitably achieve both of reduction of a discharge amount of nitrogen oxides and reduction of fuel consumption.

摘要： A pressure pattern estimation device of a fuel injection controller of an engine estimates a pressure transition of fuel in a common rail. A surplus pressure range calculation device of the fuel injection controller calculates a surplus pressure range in which pressure pattern data provided by the pressure pattern estimation device exceeds a target common rail pressure. The fuel injection controller releases the common rail pressure to a lower-pressure side by operating a pressure reduction valve of the common rail to eliminate the surplus pressure range calculated by the surplus pressure range calculation device. Thus, the common rail pressure (injection pressure) during an injection period is smoothed.
