In vehicles including both a hydraulic fuel system and a traditional power steering system, the present invention utilizes a single hydraulic pump to power both systems to increase engine efficiency and reduce engine part count. Likewise, the present invention utilizes a single hydraulic pump to power both a hydraulic fuel system and a fan drive system in engines including both engine subsystems. Further, for vehicle engines including passenger compartment heating systems, the present invention increases engine efficiency by allowing the heating system to operate effectively, even shortly after a cold start. |
