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