Fully flexible exhaust valve actuator control systems and methods |
| 摘要 |
A system for a vehicle includes a mode control module and a valve control module. The mode control module selectively sets a desired ignition mode for an engine to one of a spark ignition (SI) mode and a homogenous charge compression ignition (HCCI) mode. Using a fully flexible valve actuator, the valve actuator module selectively adjusts closing timing of an exhaust valve in response to: the desired ignition mode transitioning from the HCCI mode to the SI mode; and the desired ignition mode transitioning from the SI mode to the HCCI mode. |

1. A system comprising:
a mode control module that selectively sets a desired ignition mode for an engine to one of a spark ignition (SI) mode and a homogenous charge compression ignition (HCCI) mode; and a valve control module that, using a fully flexible valve actuator, incrementally adjusts closing timing of an exhaust valve at least twice in response to:
the desired ignition mode transitioning from the HCCI mode to the SI mode; andthe desired ignition mode transitioning from the SI mode to the HCCI mode. |
