There are provided a power supply unit control device for an internal combustion engine driven vehicle provided with a lamp driving switch for turning lamp-driving current supplied to a vehicle headlamp from a battery charged by the output of an AC generator driven by an internal combustion engine and with a conducting control unit for controlling the lamp driving switch. The conducting control unit normally performs on/off control of the lamp driving switch at a normal duty ratio, the normal duty ratio being an on/off duty ratio for the lamp driving switch at which lamp-driving current can be kept at a value not impeding the charging of the battery, and, when the internal combustion engine decelerates, performs engine deceleration lamp conducting control, in which on/off control of the lamp driving switch at the normal duty ratio is interrupted and the lamp driving switch is controlled so that lamp-driving current necessary to suppress reductions in the brightness of the headlamp is sent to the headlamp, only for a limited length of time.

A fuel injection device for an internal combustion engine including: an injector that injects fuel to be supplied to the internal combustion engine; a battery to which a DC converter that charges a capacitor of a capacitor discharge ignition circuit is connected as a load; a control portion that is provided to operate when a power supply voltage is provided from the battery through a power supply circuit, and generates an injection command signal when fuel injection timing is detected; and an injector drive circuit that applies a driving voltage from the battery to the injector while receiving the injection command signal, wherein the device further comprises converter operation stopping portion for stopping an operation of the DC converter during set load driving stop time when the injection command signal is generated.

Fuel injection device for internal combustion engine

An ignition control system for an internal combustion engine comprising a signal generator to generate pulse signals at a peculiar rotation angle position of the internal combustion engine and a position detection circuit to output a position detection signal whenever a zero cross point of a waveform of an output from a magneto AC generator driven by the engine is detected whereby when the engine should start, the engine is ignited as the signal generator generates the pulse signal, when the engine is idling, it is ignited as the position detection circuit outputs the position detection signal during the period after the pulse signal is generated and before the next pulse signal is generated and in the area exceeding the idling rotational speed, it is ignited at the ignition position arithmetically operated by a microcomputer.
