    • When a control valve 48 allows communication through a fuel drain channel C3, fuel flows into an inner control chamber R2i from an outer control chamber R2o through a communication channel 47 and flows out from the inner control chamber R2i to a fuel tank T. The flow of fuel through the communication channel 47 generates a differential pressure between inner control pressure Pci and outer control pressure Pco (Pco>Pci). Thus, an outer differential pressure immediately after an outer valve opening time can be set small, thereby restraining an increase in the unburnt HC content of exhaust gas at low load, which could otherwise result from a high rising speed of an outer needle valve 42 immediately after the outer valve opening time. Also, an inner differential pressure immediately after an inner valve opening time can be set large, thereby restraining an increase in the smoke content of exhaust gas, which could otherwise result from a low rising speed of an inner needle valve 43 immediately after the inner valve opening time.
    • 当控制阀48允许通过燃料排放通道C3进行连通时,燃料从外部控制室R2o通过连通通道47流入内部控制室R2i,并从内部控制室R2i流出到燃料箱T.流动 的燃料通过连通通道47产生内部控制压力Pci和外部控制压力Pco(Pco> Pci)之间的差压。 因此,可以将外部开阀时间之后的外部差压设定得较小,从而抑制在低负载下排气的未燃HC含量的增加,这可能由外部针阀42的立即上升速度引起 后外阀打开时间。 此外,内部开阀时间之后的内部差压可以设定得较大,从而可以抑制排气的烟雾含量的增加,否则,内部阀 营业时间。

    • A fuel injection valve (2) includes a first injection hole group (14), a second injection hole group (15), a control chamber (20), a first needle valve (12), and a second needle valve (13). The first needle valve (12) opens/closes an injection hole in the first injection hole group (14). The second needle valve (13) opens/closes an injection hole in the second injection hole group (15). Lifting of the first needle valve (12), and lifting of the second needle valve (13) are controlled by a pressure of fuel in the control chamber (20). An automatic valve (32) is further provided to change a flow rate at which the fuel flows into the control chamber (20), or a flow rate at which the fuel flows out from the control chamber (20), based on a common-rail pressure in a fuel supply source (1), when the needle valves (12, 13) are lifted. Thus, the fuel injection valve (2) injects fuel at the optimum fuel injection rate in various engine operating states.
    • 燃料喷射阀(2)包括第一喷射孔组(14),第二喷射孔组(15),控制室(20),第一针阀(12)和第二针阀(13)。 第一针阀(12)打开/关闭第一喷射孔组(14)中的喷射孔。 第二针阀13打开/关闭第二喷射孔组15中的喷射孔。 通过控制室(20)内的燃料压力来控制第一针阀(12)的提升和第二针阀(13)的提升。 还设置有一个自动阀(32),用于改变燃料流入控制室(20)的流量,或燃料从控制室(20)流出的流量, 当针阀(12,13)被提升时,燃料供应源(1)中的轨道压力。 因此,燃料喷射阀(2)以各种发动机工作状态以最佳燃料喷射速率喷射燃料。

    • The present invention provides an intake control valve which is able to reduce intake air leakage, control the amount of intake air with high accuracy, and to allow easy installation to an intake manifold. The intake control valve of an intake control device according to the present invention has a valve body, a case, and an actuator. The valve body is rotatably installed in the case, opening and closing an openingclosing passage formed in the case. The case is fitted with the actuator, which functions to rotate the valve body. In the meantime, the intake manifold is provided for a mounting bore formed for insertion of the case. On the outer side of the case are installed sealing members, which contact the wall surface of the mounting bore to prevent air leakage. The intake control valve is installed in the mounting bore formed in the intake manifold after assembling the valve body, the case and the actuator into one unit.
