摘要：
A control system for an engine includes first and second modules. The first module determines an oxygen concentration within an intake manifold of the engine. The second module regulates a flow of exhaust gas recirculation (EGR) into the intake manifold based on the determined oxygen concentration. In a homogeneous charge compression ignition (HCCI) engine, the second module may also disable an HCCI combustion mode of the HCCI engine based on the oxygen concentration.
