SECTION VI. Engine Fuel Systems
3-11. General.
The engine fuel system provides the pressurized fuel needed for proper operation of a
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.
