Abstract
An auto-choke control device maintains good startability at the time of restarting at high temperature without need of a thermostat specific for an auto-choke. An engine temperature detection device is drivably controlled by a control circuit in response to the engine temperature. A switching detection circuit detects ON or OFF operation of a main switch connected to the control circuit. A self-hold circuit automatically holds power to the control circuit when the main switch is changed from an ON state to an OFF state.
Claims3
An auto-choke control device having
- engine temperature detecting means connected to a control circuit and adapted to be drivably controlled through said control circuit in response to the engine temperature,
- said auto-choke control device characterized in that
- a switching detection circuit for detecting ON or OFF operation of said main switch is connected to said control circuit and
- a self-hold circuit is provided for automatically holding power to said control circuit and maintaining a heater in an ON state when said main switch is changed from an ON state to an OFF state and an engine is stopped.
