    Abstract: A fuel injection device of a diesel engine capable of smoothly starting the diesel engine to match an environment around the engine by saving a fuel, reducing the exhaustion of carbon dioxide, and suppressing black smoke in starting the diesel engine. A rack (45) is operated by an actuator (41) from a lowest rack position to a starting increased fuel amount position at a lower speed than that at which the rack is operated by the actuator from the lowest rack position to the starting increased fuel amount position at the maximum operating speed. The operating speed of the rack (45) is set in two stages, and the later operating speed of the rack is reduced less than the operating speed of the rack up to a set intermediate rack target value P2. Then, the operating amount of the rack (45) per hour is reduced after the ignition of the engine (1) is recognized. Also, the operating speed of the rack (45) is controlled according to an atmospheric temperature in starting the engine.

    Abstract translation: 一种柴油发动机的燃料喷射装置，其能够通过节省燃料，减少二氧化碳的排出并抑制起动柴油发动机的黑烟，平稳地起动柴油发动机以匹配发动机周围的环境。 致动器（41）由机架（41）从最低的机架位置运行到起动增加的燃料量位置，其速度低于由执行机构从最低机架位置运行到起动增加燃料的机架 金额位置处于最大运行速度。 机架（45）的运转速度分为两个阶段，机架的后期运行速度比机架的运行速度降低到设定的中间机架目标值P2以下。 然后，在识别到发动机（1）的点火之后，每小时的齿条（45）的操作量减少。 此外，起动发动机时，根据大气温度来控制齿条（45）的运转速度。

    Abstract: In an injection control device for a fuel injection pump comprising: a water temperature sensor; a cold start device (CSD) for advancing a fuel injection timing to an engine when started up in a low temperature; and a controller, the controller recognizes a value T of water temperature by a signal from the water temperature sensor, and activates the CSD when the engine is started up and when the value of water temperature recognized by the controller (recognized value T of water temperature) is lower than a threshold value Tc of water temperature. If a value V of voltage of a power source of the controller becomes lower than a threshold value Vn of the voltage of the power source during activation of the CSD, a value Tn of water temperature recognized by the controller immediately before the value of voltage of the power source becomes lower than the threshold value of voltage of the power source is maintained as the value T of water temperature recognized by the controller for activating the cold start device.
