Automatic start/stop apparatus for cyclical engine operation

摘要

Automatic control apparatus for starting and then stopping and for continuing cyclical operation of an engine including two timer means, one for determining the running/not running ratio of the engine and the other for determining how long starting power is applied to the engine start system, typically the solenoid of a starter motor. One embodiment includes a vacuum switch for sensing and preempting the second timer operation when the engine is started and there is a vacuum present in the manifold. The preferred embodiment also includes adjustable controls for setting both timer means, these same means having switching contacts capable of carrying full power to the solenoid or other engine start component.
