Abstract
A method and internal combustion engine operable in a premixed charge compression ignition mode, comprising a combustion chamber, an intake system for delivering intake air, a mixing device that mixes a first fuel with the intake air to provide a premixed charge of air and the first fuel, a direct fuel injector adapted to directly inject a second fuel into the combustion chamber, and a control system adapted to control the direct fuel injector in a manner to provide a post-ignition injection where the second fuel is directly injected into the combustion chamber after onset of ignition of the premixed charge in the combustion chamber. The second fuel is preferably injected into the combustion chamber during combustion of the premixed charge and/or shortly after combustion of the premixed charge in the combustion chamber.
