摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control device using a needle which effectively suppresses increase in the amount of unburned hydrocarbon emission irrespective of whether evaporation properties of injected fuel is good or not, under light-load driving conditions. SOLUTION: Using electronic control (such as a piezoelectric type actuator), or a mechanism operated in response to temperature without using electronic control (such as a wax swelled with temperature increase), when the evaporation property of the injected fuel is poor (during low temperature) under predetermined light-load driving conditions, injection focused on "increasing the degree of diffusion of the injected fuel" is carried out by increasing the lifting speed of the needle, or increasing a maximum lifting amount, or increasing the number of nozzle holes, or decreasing the opening area of the individual nozzle holes. On the other hand, when the evaporation properties of the injected fuel is high (during high temperature), injection focused on "solidifying the injected fuel in a region near the nozzle holes" is carried out by decreasing the lifting speed of the needle, or decreasing the maximum lifting amount, or decreasing the number of nozzle holes, or increasing the opening area of the individual nozzle holes.

摘要翻译：解决问题：提供一种使用针的燃料喷射控制装置，其在轻载驱动条件下，无论喷射燃料的蒸发性能是否良好，都能有效地抑制未燃碳氢化合物发射量的增加。
解决方案：使用电子控制（例如压电式致动器）或者在不使用电子控制（例如随温度升高的蜡膨胀）的情况下响应于温度而操作的机构），当喷射的燃料的蒸发性能差时（在低温下）在预定的轻负荷驱动条件下，通过增加针的提升速度或增加最大提升量来进行集中在“增加喷射燃料的扩散程度”的喷射，或者增加数量的喷嘴孔，或者减小各个喷嘴孔的开口面积。另一方面，当喷射燃料的蒸发性能高时（高温时），通过降低针的提升速度来进行集中于在喷嘴孔附近的区域中固化喷射燃料的注射，或减小最大提升量，或者减少喷嘴孔的数量，或者增大喷嘴孔的开口面积。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a control device of a cooling system, capable of suppressing excessive correction when a control amount of an engine is subjected to a cold correction.SOLUTION: A cooling channel cools an engine by cooling water that passes in the channel. A cooling water temperature acquiring means acquires a temperature of the cooling water by estimation or actual measurement. A control amount determining means determines a control amount of the engine based on the acquired cooling water temperature. When the acquired cooling water temperature is lower than a warm-up completion temperature, the control amount determining means determines a control amount of the engine by differentiating a relationship between the acquired cooling water temperature and the engine control amount in a period of regulating a passing amount of the cooling water and a period of canceling the regulation of the passing amount of the cooling water; and within a predetermined period immediately after starting the engine, the control amount determining means determines a control amount of the engine based on a relationship between the cooling water temperature during canceling the regulation of the passing amount of the cooling water and a control amount of the engine.
