摘要： Disclosed herein is a fuel injector for an internal combustion engine, which includes a high pressure pump for pressure feeding high pressure fuel of the internal combustion engine; a fuel rail for accumulating the fuel that has been pressure fed by the high pressure pump; an injection valve for injecting, into a cylinder, the fuel accumulated in the fuel rail; a fuel pressure sensor for detecting the pressure of the fuel that is accumulated in the fuel rail; an electromagnetic relief valve for discharging the pressure accumulated fuel of the fuel rail; and an electronic control unit for controlling opening and closing of the electromagnetic relief valve. The electronic control unit repeats the opening and closing of the relief valve to discharge the fuel pressure in stages so that the fuel pressure in the fuel rail is decreased down to the target fuel pressure.

摘要： In an internal combustion engine provided with a high-pressure fuel pump, if the discharging rate of the high-pressure fuel pump is greater than the injection quantity of fuel injected from a injector with the high-pressure fuel pump remaining uncontrollable due to failure or the like, it is probable that the fuel pressure in a common rail unintentionally rises to affect the injector. A high-pressure fuel supply apparatus is provided to solve such a problem.A high-pressure fuel supply apparatus according to the present invention is configured such that if the high-pressure fuel supply apparatus or a control apparatus thereof causes malfunction to increase the pressure in the common rail, the pressure in the common rail does not exceed pressure affecting the flow characteristic and spray characteristic of the injector after recovery from the malfunctioning state.

摘要： A catalytic converter for purifying exhaust gas from an automotive vehicle engine. The catalytic converter is composed of a metallic carrier for catalyst metal, disposed inside a casing. The metallic carrier is constructed of a main sheet metal structure which is formed by turning up an elongate flat sheet metal in a zigzag manner in cross-section, so that the main sheet metal structure has a plurality of parallel flat portions. The adjacent flat portions define therebetween a space. The main sheet metal structure is coated over all of its surfaces with an electrically insulative alumina layer. A plurality of corrugated sheet metal spacers are disposed and secured in the respective spaces thereby to define fine gas passages through which exhaust gas flows. Thus, the main sheet metal structure is electrically insulated from the corrugated sheet metal spacers, so that electric current is passed only through the main sheet metal structure. The main sheet metal structure serves as a heater element for promoting activation of the catalyst metal.
摘要翻译：一种用于净化机动车辆发动机废气的催化转化器。催化转化器由催化剂金属的金属载体组成，设置在壳体内。金属载体由主金属板结构构成，该主金属板结构通过以锯齿形的方式在横截面上卷起细长的平板金属而形成，使得主金属板结构具有多个平行的平坦部分。相邻的平坦部分之间限定了一个空间。主要金属片结构在其所有表面上涂覆有电绝缘氧化铝层。多个波纹金属间隔件被设置并固定在各个空间中，从而限定废气流过的细小的气体通道。因此，主金属板结构与波纹金属间隔件电绝缘，使得电流仅通过主金属板结构。主要的金属板结构用作促进催化剂金属活化的加热元件。
