G3516C Engine design (A) Inlet valves (B) Exhaust valves (C) FlywheelFuel System (Air/Fuel Ratio Control)
The fuel system includes these components:
Fuel metering valve
Engine control module (ECM)
Inlet Manifold Pressure 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 air/fuel mixture is cooled in the aftercooler. The mixture enters the manifold through a throttle which is electronically controlled.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 retarding of the ignition timing will take place when excessive detonation is sensed in that cylinder. If the maximum retarding 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 located at the entrance of each inlet port. If the engine backfires, the flame arresters prevent the fire from entering the air/fuel mixture.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.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.The circuit for the aftercooler may be combined or the circuit for the aftercooler may be separate circuits. In the combined system, a pump circulates water through both the aftercooler and oil cooler cores. The combined system uses a thermostatic control to regulate the oil temperature. The thermostatic control prevents overcooling.For a more detailed description, refer
