Engine Systems

The engine systems are as follows:

Fuel System

The 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, 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.

Exhaust Gas Recirculation System

The Exhaust Gas Recirculation (EGR) system consists of an EGR cooler, EGR
valve and actuator. The EGR actuator opens and closes the EGR valve to allow hot
exhaust gas to enter the EGR cooler. Heat is extracted from the exhaust gas,
