WASHER 1483528 - Caterpillar

Intended Use
This Power Generator is intended to generate electrical power.Engine Description
Fuel System (Air/Fuel Ratio Control)
The fuel system includes these components:
Fuel metering valve
Engine control module (ECM)
Inlet Manifold Pressure Sensor
Knock sensor
Load Signal
Inlet manifold temperature sensorThe fuel metering valve controls the flow of fuel to the engine. The ECM determines the requirement for the mixture of air and fuel. The ECM sends a signal to the fuel metering valve. The fuel metering valve controls the volume of the gas flow to the engine.The fuel flows through the fuel metering valve into the air inlet elbow. The mixture of air and fuel flows through the turbocharger compressor. The mixture enters the aftercooler through a throttle which is electronically controlled. The air/fuel mixture is cooled in the aftercooler. The mixture then enters the inlet manifold.The ECM sends an electronic throttle signal to the electronic actuator. The throttle is controlled by the actuator.Ignition System
The engine is equipped with an electronic ignition system. The system provides dependable firing and low maintenance. The system provides precise control of the spark and the ignition timing for each cylinder.The system also provides diagnostic capability that enhances troubleshooting.The engines are equipped with protection from detonation. A detonation sensor is located between every two cylinders. The ignition timing is delayed for a cylinder when excessive detonation is sensed in that cylinder. If the maximum delayed position is attained and detonation continues to occur, the ECM shuts down the engine.The engines are equipped with flame arresters. The flame arresters are at the entrance of each inlet port. If the engine backfires, the flame arresters prevent the fire from entering the intake manifold.Lubrication System
The engine lubrication oil is circulated by a gear-driven pump. The oil is cooled and filtered. A bypass valve provides unrestricted flow of lubrication oil to the engine parts if the oil filter elements become plugged.The prelube pump, if equipped, is controlled by the engine Electronic Control Module (ECM). Settings can be modified in ET. The recommended prelube operation time is 120 seconds.Cooling System
The cooling system uses a water pump. The cooling system has temperature regulators that regulate the temperature of the coolant. The temperature depends on the application.The turbocharged engine has a Separate Circuit Aftercooler (SCAC). The temperature depends on the engine rating and the application.For a more detailed description, refer to the Systems Operation/Testing and Adjusting manual.Description of the Generator
The brushless generator can be used with the following loads: mixed loads of motors and lights, SCR-controlled equipment, computer centers, and petroleum drilling applications.Generators are utilized in three-phase full-wave excitation and regulation. The generators are four pole designs. The generators have six lead configurations.This generator set is to be used in utility parallel mode.Island Mode
Island Mode refers to an application for Generator Sets that is not paralleled to a public utility. In this operational state, the gas engine must maintain torque and crankshaft speed during steady state operations.
