ABSTRACT:
A method includes operating an internal combustion engine according to a four-stroke combustion cycle. The four-stroke combustion cycle includes a combustion stroke, an exhaust stroke, an intake stroke and a compression stroke. A valve associated with a cylinder of the internal combustion engine is opened at a first time during the four-stroke combustion cycle. The valve is closed at a second time during the four-stroke combustion cycle. The valve is opened at a third time during the four-stroke combustion cycle. The valve is closed at a fourth time during the four-stroke combustion cycle.
