Abstract
An engine system comprises a hydraulically actuated fuel injection system and an EGR valve circuit connected via a fluid flow passage that provides hydraulic fluid to both the fuel injection system and to the EGR valve circuit. The hydraulically actuated system includes a high pressure pump. The fluid control passage is in fluid communication with an outlet from the high pressure pump.
