In diesel engines, the fuel must be in a highly atomized form for proper combustion. Usually, this is accomplished with a plunger and cylinder arrangement (solid injection), which forces accurately measured amounts of liquid fuel into the combustion chambers through atomizing nozzles. Compressed air (air injection) is sometimes used in place of a plunger. These injectors are widely used in such diesel equipment as railroad locomotives, trucks, buses, earthmovers, ships, and stationary power plants and are sometimes found in aircraft and motor truck spark-ignition engines.
