Abstract
An internal combustion engine includes an engine assembly that defines a bore, and a piston disposed and moveable within the bore. The piston and the engine assembly cooperate to define a combustion chamber therebetween. A direct injection fuel system directs a fuel spray into the combustion chamber along a linear path. The combustion chamber includes a contoured surface having a plurality of annular recesses. The contoured surface divides and re-directs the fuel spray from the linear path into each of the annular recesses to form a plurality of independent rotating vortices.
