    Abstract: A method for controlling ignition timing of an internal combustion engine and an apparatus for practicing the method are disclosed which are adapted to determine ignition timing depending upon information on an engine speed detected, to thereby control the ignition timing. Pulsin signal counting is started evey time when a reference signal is generated from a signal generator to count first, second and third numbers N1, N2 and N3 of pulse signals, to thereby obtain information on an engine speed depending upon the difference between time T2 when the counting of the second number of pulse signals is completed and time T1 when that of the first number of pulse signals is completed, and then the information is used for obtaining ignition timing measuring time equal to a period of time between time T3 when the counting of the third number of pulse signals is completed and target ignition timing T1. The measuring of the ignition timing measuring time is started after the counting of the third number N3 of pulse signals is completed.

    Abstract: A fuel injection system wherein a microcomputer carries out an operation of a fuel injection period using a generator mounted on an internal combustion engine as a power supply is provided, which is capable of preventing excessive feeding of fuel to the engine during restarting of the engine to ensure smooth restarting of the engine. The fuel injection system includes a charge storing circuit for carrying out charging of a charge storage element during initial starting of the engine, a discharge circuit for permitting discharge of the charge storage element to be carried out over a long period of time, and a signal generating circuit for generating an initial starting signal when the amount of charges in the charge storage element is below a predetermined level and a restarting signal when the amount reaches the predetermined level or more. Where the restarting signal has been generated at the time when the microcomputer starts to operate, it executes an operation of a fuel injection period which provides a fuel injection rate suitable for the restarting.

    Abstract: A fuel injection system for an internal combustion engine capable of being normally operated while using an output of a generator driven by the internal combustion engine as a power supply therefor. The system includes a switching circuit for switching a driving current fed to an injector from a main power circuit which uses the output of the generator as a power supply therefor. The switching circuit is controlled by a switch control circuit for which a power supply comprises a control power circuit. The control power circuit includes a storage unit for storing electric power therein, so that the storage unit may be act as a power supply when the output of the main power circuit is reduced, to thereby feed the switch control circuit with a power supply voltage of a level equal to or above an operable level. The storage unit is charged by the output of the main power circuit or an output of a generating coil for a control power supply provided in the generator in a manner to be separate from a generating coil for the main power supply.

    Abstract: A control system for an internal combustion engine adapted to precisely control an ignition position of the internal combustion engine in accordance with a revolution of the engine detected from an output of a pick up coil generating a signal in synchronism with a rotation of a crank shaft and an opening degree of a throttle valve by use of a microcomputer. Whenever an output of a throttle sensor is sampled, a three-dimensional map providing a relation among the revolution of the engine, the opening degree of the throttle valve and the ignition position is transferred into a two-dimensional map providing a relation between the revolution of the engine and the ignition position whereby the ignition position is determined by the two-dimensional map as soon as the revolution of the engine is detected so that the ignition is operated when the determined ignition position is detected.

    Abstract: A marine power device capable of preventing a failure in actuation of constantly-driven loads required to be constantly actuated for continuing operation of an internal combustion engine, when various loads are actuated using both a magneto driven by the engine and a battery driven by the magneto as a power supply in a ship in which an outboard motor is used as a propelling equipment. The device includes a switch which functions to separate occasionally-driven loads increased in power consumption and the battery from the magneto when the battery is reduced in output voltage thereof to a level of failing to actuate the constantly-driven loads due to connection of the occasionally-driven loads to the battery or overdischarge of the battery. The switch is arranged at a position which does not affect flowing of a drive current fed from the magneto to the constantly-driven loads.
