Compression-ignition engine configuration for reducing pollutants and method and system thereof

摘要

In accordance with one aspect of the present technique, a method of reducing pollutant emissions from a compression-ignition engine is provided. The method includes adjusting timing of fuel injection into a combustion chamber of a piston-cylinder assembly of the compression-ignition engine. The method of adjusting timing of fuel injection includes indexing a drive mechanism intercoupling a camshaft to a crankshaft by at least one tooth away from a standard position. The method of adjusting timing of fuel injection further includes adjusting a pre-stroke of a plunger of a fuel injector assembly.
