Engine Systems
The engine systems are as follows:
Three-Filter Fuel System
The three-filter fuel system consists of DDEC control system, fuel injectors, low
and high pressure pumps, fuel filter module, prefilter, water separator/coalescer,
final filter, and the necessary connecting fuel lines. The common rail system with
injectors provides amplification for better fuel atomization.
Two-Filter Fuel System
The two-filter fuel system consists of DDEC control system, fuel injectors, low and
high pressure pumps, fuel filter module, prefilter, coalescer/final filter, and the
necessary connecting fuel lines. The common rail system with injectors provides
amplification for better fuel atomization.
Lubrication System
The lubrication system consists of an oil pump, oil cooler, cartridge-style oil filter,
pressure regulator valve, and oil pressure sensor. Clean, pressurized oil is fed to all
components via passages in the engine block and cylinder head.
Air System
Outside air enters the engine through the air filter and is drawn to the turbocharger
and then is compressed, and forced through the air-to-air charge cooler (heat
exchanger) and is cooled. Next, it flows to the intake manifold and into the
cylinders, where it mixes with atomized fuel from the injectors.
For optimum engine protection from dust and other airborne contaminants, service
the dry-type air cleaners used when the maximum allowable air restriction has been
reached.
Cooling System
A radiator/thermo-modulated fan cooling system is used on the engine. This system
has a centrifugal-type coolant pump to circulate coolant within the engine. One
full-blocking type thermostat located in the coolant module attached to the left side
of the cylinder block controls the flow of coolant. The coolant module incorporates
the oil cooler, oil filter, coolant filter (model year 2014 and prior engines only), and
coolant pump.
Electrical System
The electrical system consists of a starting motor, starting switch, battery-charging
alternator, storage batteries, and necessary wiring.
Exhaust System
Hot exhaust gas from the exhaust manifolds is used to drive the turbocharger.
