Abstract

A combustion system for an internal combustion engine includes a cylinder wall; a cylinder head disposed at an end of the cylinder wall, an internal surface of the cylinder wall and the cylinder head defining a combustion chamber; a fuel injector having a discharge nozzle disposed within the combustion chamber and configured to discharge a fuel jet along a fuel jet axis; and a bluff body disposed within the combustion chamber, the fuel jet axis intersecting an exterior surface of the bluff body. The exterior surface defines a first aperture and a second aperture therethrough, and an interior surface of the bluff body defines a first flow passage extending from the first aperture to the second aperture. The first aperture faces away from the fuel jet axis and the second aperture faces away from the fuel injector along the fuel jet axis.
