A hydramechanical governor controls the fuel injection pump output in order to maintain the engine rpm that is selected by the operator.Fuel is metered and pumped by a fuel injection pump under high pressure to the fuel injector nozzles (one per cylinder). The automatic timing advance provides the best fuel injection timing over the full range of engine rpm.Engine Cooling and Lubrication
The cooling system consists of the following components:
Centrifugal pump that is driven by gears
Water temperature regulator which regulates the engine coolant temperature
Oil cooler and a radiator which incorporates a shunt systemThe engine lubricating oil that is supplied is cooled. The 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 the Operation and Maintenance Manual as a guide for required engine maintenance.Expected engine life is generally predicted by the average power that is demanded. The average power that is demanded is based on fuel consumption of the engine over a period of time. Reduced hours of operation at full throttle and/or operating at reduced throttle settings result in a lower average power demand. Reduced hours of operation will increase the length of operating time before an engine overhaul is required. For more information, refer to the Operation and Maintenance Manual, "Overhaul Considerations" topic (Maintenance Section).
