Abstract
A method of operating a dual-fuel combustion system includes reciprocating a piston between a bottom dead center and a top dead center of a cylinder, the piston including a piston bowl, a circumferentially extending recess located radially outside of the piston bowl, and a plurality of diverters in the recess. The method includes opening an intake valve to introduce a first fuel, and injecting, by a set of fuel injector orifices substantially aligned with the diverters, a second fuel toward the diverters. The method also includes autoigniting the second fuel to ignite the first fuel.
