Systems and methods for controlling engine combustion stability |
| 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. |

1. A control system for an engine, the control system comprising:
a first module that determines an oxygen concentration within an intake manifold of the engine; and a second module that regulates a flow of exhaust gas recirculation (EGR) into the intake manifold based on the determined oxygen concentration, wherein the engine is a homogeneous charge compression ignition (HCCI) engine, and wherein the second module selectively disables an HCCI combustion mode of the HCCI engine when the EGR valve is closed based on the determined oxygen concentration. |
