Engine Cooling and Lubrication
The cooling system consists of the following components:
Gear-driven centrifugal water pump
Water temperature regulators which regulate the engine coolant temperature
Gear-driven oil pump (gear type)
Oil coolerThe engine lubricating oil is also filtered. Bypass valves provide unrestricted flow of lubrication oil to the engine components during the following conditions:
High oil viscosity
Plugged oil cooler or plugged oil filter elements (paper cartridge)Engine Service Life
Engine efficiency and maximum utilization of engine performance depend on the adherence to proper operation and maintenance recommendations. In addition, use recommended fuels, coolants, and lubricants. Use this Operation and Maintenance Manual as a guide for required engine maintenance.Expected engine life is predicted by the average power that is demanded. The average power that is demanded is based on fuel consumption of the engine over a time period. For more information, refer to the Operation and Maintenance Manual, "Overhaul Considerations" topic (Maintenance Section).Engine Specifications
Note: The front end of the engine is opposite the flywheel end of the engine. The left and the right sides of the engine are determined from the flywheel end. The number 1 cylinder is the most forward cylinder.

The brushless generator can be used with the following loads: mixed loads of motors and lights, SCR-controlled equipment, computer centers, installations of communications and petroleum drilling applications.The generator set packages can be utilized for prime power generation or standby power generation.The generator is utilized in three-phase full-wave excitation and regulation. The generator is a four pole design with twelve-lead configuration. The generators can produce electrical power in either 50 Hz or 60 Hz applications.Power Module Enclosure
Basic Container
The enclosure for the power module is a shipping container that is mounted to an undercarriage chassis. The container meets the following standards and regulations:
ISO/TC 104 Requirements for cargo containers
ANSI/MH5.1 Basic requirements for cargo containers
ANSI/MH5.1.1 Requirements for closed van containersVertical Discharge Panel
Illustration 2 g01297394
Vertical discharge panel
The vertical discharge panel is installed in power modules that are equipped with vertical radiators. The panel directs hot air from the radiator and engine exhaust through an opening in the roof. The panel directs the hot air away from the surrounding area of the power module.Fire Extinguishers
Fire extinguishers and fire suppression systems are available as an option.Fuel Storage and Fuel Delivery
XQ800 Fuel tank
A 4732 L (1250 US gal) fuel tank is mounted in the front of the power module. The fuel tank can supply fuel for the engine for approximately 19 hours of operation at full continuous load. The fuel tank can supply fuel for the engine for approximately 24 hours of operation at 75% or the standby rating.Fuel Transfer System
A fuel transfer system is standard for the power module. During the operation of the power module, the fuel transfer system will automatically fill the fuel tank from a fuel reservoir.
