16 ENGINE SYSTEMS Engine Systems The primary engine systems are Air Management and Fuel Management, which share some subsystems or have a subsystem that contributes to their operation. The ICP system uses lube oil for hydraulic fluid to actuate the fuel injectors. The Fuel Supply System pressurizes fuel for transfer to the fuel injectors. The Electronic Control System controls the Air Management System and Fuel Management System. The Lube Oil System provides lubrication and heat transfer to engine components. The Coolant System provides heat transfer for EGR gases and lubrication oil.
