COMBUSTION CHAMBER OF AN ENGINE

摘要

A combustion chamber system for an engine includes a main combustion chamber and an auxiliary combustion chamber. The main combustion chamber is defined by a cavity recessed on an operative top face of a piston crown of a piston that traverses within the cylinder of the engine, inside surface of cylinder wall and a cylinder head. The main combustion chamber receives fuel to be combusted from an injector disposed on the cylinder head. The auxiliary combustion chamber is defined by an auxiliary cavity extending radially outward from and in fluid communication with the cavity, wherein the auxiliary cavity creates vortices and directs fuel flow received therein towards a center of the cylinder, thereby diverting the fuel flow away from wall quench zones and fuel entrapping crevices of the cylinder wall to prevent incomplete combustion of fuel caused by quenching and entrapment of fuel at the cylinder wall.
