An internal combustion engine may have an engine block having a plurality of cylinders. The internal combustion engine may also have a piston reciprocatingly mounted with each cylinder and defining a combustion chamber therebetween. The internal combustion engine may also be configured with a fuel injector communicating fuel to the combustion chamber, the fuel creating a plurality of flame plumes when ignited. The internal combustion engine may also have a piston crown extending from the piston and defining a piston bowl, the piston crown including a circumferential wall terminating in a top ledge. Further, the internal combustion engine may include a plurality of fluid passageways in the piston crown, each fluid passageway including an ingress in the top ledge and an egress in the circumferential wall proximate the piston bowl.
