TM 9-2350-275-BD ENGINE SECTION VI. Engine Fuel System 3-12. General. The engine fuel system provides the pressurized fuel needed for proper operation of the compression ignition engine. An engine mounted mechanical fuel pump provides fuel to the fuel injectors which inject fuel into the cylinder in the proper quantities. The fuel injectors are cam-operated by pushrods and a rocker arm arrangement to provide fuel injection at the proper time. Figure 3-13. INJECTOR FAILURE General. 3-4. Engine Fuel System Fuel injector failure should be noticeable through a loss of power or excessive smoke. Within the Detroit Diesel family of engines the injectors are physically interchangeable although their operating characteristics differ for the engine configuration they are designed for. Injectors should be exchanged, if possible, in full sets to keep engine operation balanced between cylinders. Single replacement is, however, possible. The defective injector can be located by following this procedure. 3-11
