Abstract
A fuel injection system for a diesel engine operating at retarded fuel injection timing includes a fuel cam configured to increase a fuel injection pressure and decrease a fuel injection duration, thereby improving fuel atomization and combustion in a plurality of engine cylinders and improving an indicated efficiency of the engine and reducing exhaust emissions. The fuel cam is oriented in a phase relationship with a compression stroke top-dead-center position to accommodate the retarded fuel injection timing and to optimize an engine brake efficiency and performance.
