A method of operating an internal combustion engine employs exhaust gas recirculation (EGR) in combination with directly injected gaseous fuels that are burned within the engine in a stratified combustion mode. An engine that employs EGR includes an injector adapted to provide a high pressure quantity of fuel into a combustion chamber within a given pressure range, at a given angle and through a nozzle hole size to help provide for EGR tolerance and, consequently, reduce emissions. |
