Abstract
An internal combustion engine operable in a premixed charge compression ignition mode and a method for operating the engine, the engine including an engine body with a piston assembly, a combustion chamber formed in the engine body by the piston assembly, an intake system for delivering intake air to the combustion chamber during an intake stroke, 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 at least one early control injection, and preferably, a plurality of early control injections of the second fuel into the combustion chamber before start of combustion of the premixed charge.
