Abstract
A fuel introduction system introduces fuel to an internal combustion engine operating on a six-stroke combustion cycle including a first compression stroke, a first power stroke, a second compression stroke, and a second power stroke. The fuel introduction system includes a first orifice set for introducing a first fuel charge to a combustion chamber of the engine during the first compression stroke and/or power stroke and a second orifice set for introducing a second fuel charge to the combustion chamber during the second compression stroke and/or power stroke. Combustion of the second fuel charge can assist in burning particulate matter left in the combustion chamber from combusting the first fuel charge. The first and second orifice sets can be configured to differentiate the first and second fuel charges by, for example, fuel quantity or spray pattern.
