    • An ignition apparatus for an internal combustion engine includes a reduced number of component parts which can be arranged or laid out without difficulty within a limited space such as a vehicle engine room. The apparatus can be manufactured at low costs and it is also highly resistant to electrical noise from adjacent electrical and electronic elements and hence has improved reliability in operation. The apparatus includes an ignition coil connected to a spark plug which has electrodes present in a combustion chamber of a cylinder, a switch unit for controlling power supply to the ignition coil, and an ion current sensing unit connected to the spark plug for sensing an ion current generated between the electrodes of the spark plug during combustion of a mixture in the combustion chamber. The ignition coil and the switch unit, or the ion current sensing unit and the switch unit, or all of these elements, are integrally formed with each other to provide an integral assembly. In a preferred form, the switch unit and the ion current sensing unit comprise a hybrid integral circuit. The switch unit includes a switch in the form of a power transistor connected to the ignition coil, and a switch driver for driving the switch. The power transistor can be formed separately from the ion current sensing unit whereas the switch driver can be integrally formed with the ion current sensing unit.

    • An integrally molded Hall sensor device for detecting the crankshaft angle of an automotive engine. The injection mold includes a projection 1a extending into a cavity and having a width equal to that of a gap through which a magnetic shutter passes. Before the molding, the parts are assembled utilizing a skeletal frame having first and second opposing pairs of vertically extending guide members, and the inserted electrical conductor for the Hall IC is embedded in the frame. The Hall IC and associated parts are accommodated in a holder, which is thereafter fitted between the first pair of guide members, to be translatable toward the gap; a magnetic circuit member including a permanent magnet is fitted between the second pair of the guide members to be translatable toward the gap. The assembled parts are then put into the mold such that the surfaces flanking the gap are positioned at respective sides of the projection. A flowing resin is injected into the mold such that the holder and the magnetic circuit member are driven by the flow against the respective side surfaces of the projection. Thus, the width of the gap can be precisely determined by the width of the projection without utilizing jigs.

    • A method of and apparatus for generating a cylinder discriminating signal in a distributor for an internal combustion engine are disclosed. The cylinder discriminating signal is generated by a combination of a cylinder discriminating reluctor installed on a centrifugal spark advance member and a cylinder discriminating sensor attached to a vacuum spark advance plate to detect approach and passage of the cylinder discriminating reluctor. The width of the cylinder discriminating reluctor in the direction of rotation is set so as to correspond to an angle smaller than the entire range of spark advance of the ignition timing signal. The cylinder discriminating signal is advanced by both centrifugal spark advance and vacuum spark advance so as to overlap the ignition timing signal despite having a relatively narrow width. Since the width of the cylinder discriminating signal is reduced, it is possible to improve the control tolerances of the associated microcomputer.
    • 公开了一种用于在内燃机的分配器中产生气缸识别信号的方法和装置。 气缸鉴别信号是通过安装在离心式火花提前部件上的圆筒鉴别反射器与安装在真空火花提前板上的气缸识别传感器的组合产生的,以检测气缸识别反射器的接近和通过。 气缸判别偏振器在旋转方向上的宽度被设定为对应于小于点火正时信号的整个火花提前范围的角度。 即使具有相对较窄的宽度,气缸识别信号也通过离心式火花提前和真空火花提前进行提升,从而与点火定时信号重叠。 由于气缸识别信号的宽度减小,所以可以提高相关微型计算机的控制公差。
