TM 9-2350-273-BD ENGINE SECTION VI. Engine Fuel Systems 3-14. General. The engine fuel system provides the pressurized fuel needed for proper operation of a compression ignition engine. An electrical fuel pump provides fuel to the fuel injection pump which distributes high-pressure fuel pulses to the 12 injectors. The pulse is timed to the compression stroke of the piston in each cylinder. Fuel is injected into the cylinders in the proper quantities to ensure complete combustion. The engine houses a water separator assembly which is equipped with an automatic dump sensor. As water contacts the sensor the system will drain the contaminated fuel. Three fuel filters reside the separator ensure that water or other contaminants do not enter the fuel injection circuit. Fig 3-4. Engine fuel system. 3-13
