ABSTRACT:
A display control apparatus for use in an internal combustion engine includes: a CDI type ignition circuit; an overspeed preventing circuit which can limit the engine speed to a restricted value; a first LED display unit of the light on/off type to display the amounts of oil and/or cooling water; a second LED display unit to display the circulation state of the oil and/or cooling water; and a drive circuit which switches the first and second display units to an alarm display mode and causes the overspeed preventing circuit to limit engine speed when abnormal states of the oil and/or cooling water are detected by oil level switches or by water and oil flow sensors. If power ceases, the display state is held by keep relays. When an abnormal state is detected, the driver is warned by lighting up of red LEDs and by generating a beeping sound from a buzzer.
