Abstract
An internal combustion engine includes a first cylinder having an intake valve in fluid communication with an intake manifold, and a second cylinder having an exhaust valve in fluid communication with an exhaust manifold. A transfer passage fluidly connects the first cylinder with the second cylinder. A first fuel injector is configured to provide a first fuel to the first cylinder, and a second fuel injector is configured to provide a second fuel to the second cylinder. The first cylinder operates, at times, to push a first air/fuel mixture through the transfer passage into the second cylinder. The second fuel injector is configured to provide at least one fuel injection plume into the first air/fuel mixture.
