Abstract
An engine apparatus comprising an internal combustion engine operable throughout a range of speeds including a minimum speed, a maximum speed, a first speed between the minimum speed and the maximum speed, and a second speed between the first speed and the maximum speed, the engine including an intake zone wherein relatively low pressure is created in response to engine operation, a primary fuel delivery system for delivering fuel from a fuel source to the engine for normal engine operation, a selectively actuatable secondary fuel delivery system for delivering enrichment fuel from a fuel source to the engine, and an electrical control circuit for selectively actuating the secondary fuel delivery system only when the pressure in the zone is below a predetermined level and the speed of the engine is above the first speed and below the second speed.
