Abstract
A system for a vehicle includes a mode control module and a valve control module. The mode control module selectively sets an ignition mode for an engine to one of a spark ignition (SI) mode and a homogenous charge compression ignition (HCCI) mode. In response to the ignition mode transitioning from the SI mode to the HCCI mode during a first engine cycle, the valve control module operates an exhaust valve in a high lift mode during a second engine cycle, operates an intake valve in a low lift mode during the second engine cycle, and operates the exhaust and intake valves in the low lift mode during a third engine cycle. The first engine cycle is before the second engine cycle, and the second engine cycle is before the third engine cycle.
