1. A hybrid powertrain system, comprising:
an internal combustion engine having a piston configured to reciprocate within a cylindrical bore, the piston and the cylindrical bore at least partly defining a combustion chamber; an electric generator operatively coupled to the internal combustion engine; a fuel injection system in fluid communication with at least one fuel source and the combustion chamber; and a controller operatively coupled to the fuel injection system, wherein the controller is configured to:
effect a first mixture including a first portion of fuel and a first portion of oxidizer while the internal combustion engine operates at a first predetermined load, the first mixture being lean of stoichiometric and being substantially homogeneous throughout the combustion chamber at a first start of combustion time,effect a second mixture including a second portion of fuel and a second portion of oxidizer while the internal combustion engine operates at a second predetermined load, the second mixture being lean of stoichiometric and being substantially homogeneous throughout the combustion chamber at a second start of combustion time, andeffect a third mixture including a third portion of fuel and a third portion of oxidizer while the internal combustion engine transitions from the first predetermined load to the second predetermined load, the third mixture including a fuel-rich region being rich of stoichiometric at a third start of combustion time. |
