Engine Systems Engine Systems Engine Systems The engine systems are as follows: Fuel System The fuel system consists of DDEC control system, fuel injectors, high pressure fuel rail, low and high pressure pumps, fuel filter module, prefilter, final filter, and the necessary connecting fuel lines. 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, is drawn to the turbocharger, is then compressed, 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 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.
Two thermostats located in the oil/coolant module attached to the right side of the cylinder block controls the flow of coolant. The coolant module incorporates the oil cooler, oil 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. 38 All information subject to change without notice.
