Abstract

DC60 (22/06/53) Vehicle-mounted electric power supply that combines an internal combustion engine, a drive source, a fuel injection device (26), and an electric load (19, 70). ) Vehicle power supplies include a battery (16) which powers an electric load (19, 70), an alternator (11), which charges a battery (16) with electrical power. and supplies electrical power to the electrical load (19, 70), and the electrical power supply device (12), which supplies the output power from the generator. alternating current (11) to the fuel injection device (26) to make the fuel injection device (26) work. Vehicle electrical power supplies installed in the vehicle which include: internal combustion engine, as a drive source, with fuel injection devices (26), and electric loads (19, 70). Vehicle power supplies, including batteries (16), which power electric loads (19, 70), alternators (11). ), which charges the battery (16) with electric power. and supplies electrical power to the electrical load (19, 70), and the electrical power supply device (12), which supplies the output power from the generator. AC power (11) to the fuel injection device (26) to make the fuel injection device (26) work:

Claims (4)

Disclaimers (all) that will not appear on the advertisement page: 1. Vehicle power supply installed in vehicles with combustion engines. Inside is a driving source that includes A battery that supplies electrical loads and an alternator that charges the battery with electric power. And supply power to the electrical load An alternator that charges the battery with electrical power. And supply power to the electrical load The vehicle power supply was also included. An interrupting device that interrupts the supply of power from the alternator to the battery when the condition of the battery charge does not achieve the pre-defined condition bag. The power distribution equipment is connected to the alternator and supplies the power output from the alternator to the fuel injection equipment and the control equipment of the fuel injection equipment for the running of the fuel injection equipment. When the switch has been provided Between the alternator and the combination of the fuel injection device and the control device of the The fuel injection device is on The first circuit connects the alternator to the power distribution device and the power distribution device to the battery via an interrupter device. A second circuit that connects the battery to the fuel injection device and the control device while it is fed. A timing drive and a relay device provided between the battery and the electrical load. And can switch between It is possible to connect and disconnect between the battery and the load, where the control device is interrupted in an off state for power output. From power supplies to fuel injection equipment and control equipment When the voltage of The battery is below the preset value. The control device makes the relay device off. When the control device receives a pulse that Predetermined depending on the speed of rotation of the internal combustion engine within the period Predetermined the initial principle of power distribution to the control device and the speed of rotation Of the internal combustion engine is lower than the preset value The control device keeps the relay device on. When the control device receives a pulse that A predetermined time comes within a predetermined period after the start of the power supply to Control equipment and the rotational speed of the internal combustion engine is greater than or equal to the Preset and control devices keep the relay device on When the control device does not receive a signal Pre-defined pulses within a preset period after the start of the power supply. To the regulator and the battery voltage is greater than or equal to the preset value. 2. Vehicle power supply according to claim 1, where the control device makes The relay device is on. When the conditions for the rotational speed of the internal combustion engine are Continuously for periods equal to or greater than the predetermined time period. 3. Vehicle power supply according to the clause 1 where the preset period is 110 ms 4. The vehicle power supply unit, pursuant to Clause 1 to 3, is further incorporated by a capacitor that accumulates the power output from the distribution equipment.
