START CONTROL SYSTEM USING SINGLE HYDRAULIC PUMP

摘要

A start-stop control system and method is provided utilizing a primary pump to both supply pressurized fluid to hydraulic consumers of the system and to charge one or more accumulators. When the accumulator is charged, the system will stop the fuel to the combustion engine when the operator controls of the hydraulic consumers have not been utilized for a period of time or in response to an engine off command. When the operator controls of the hydraulic consumers are again utilized, the accumulator will activate the hydraulic motor to start the combustion engine as well as providing pressurized hydraulic fluid to the hydraulic consumers.
