Abstract
In one embodiment, a combustion system for an engine is disclosed. The system includes a cylinder block that defines a cylinder bore and opposing pre-chambers located along a circumference of the cylinder bore. The system also includes a fuel injector located equidistant from the circumference of the cylinder bore that injects fuel in a direction perpendicular to a diameter of the cylinder bore. The system further includes a piston located within the cylinder bore that has a substantially conically shaped crown having fuel direction grooves that direct the fuel from the fuel injector towards the opposing pre-chambers.
