Abstract:
1. A processor-readable medium storing code representing instructions to cause a processor to perform a process, the code comprising code to: open a valve associated with a cylinder when an internal combustion engine is in a first configuration corresponding to a first rotational position of a crankshaft of the internal combustion engine to allow a first gas to flow from a gas manifold into the cylinder; close the valve associated with the cylinder when the internal combustion engine is in a second configuration to fluidically isolate the cylinder from the gas manifold, the second corresponding to a second rotational position of the crankshaft of the internal combustion engine, the second rotational position being different than the first rotational position; open the valve associated with the cylinder when the internal combustion engine is in a third configuration to allow a second gas contained with the cylinder to flow from the cylinder into the gas manifold, the third configuration corresponding to a third rotational position of the crankshaft of the internal combustion engine, the third rotational position being different from the first rotational position and the second rotational position; and close the valve associated with the cylinder when the internal combustion engine is in a fourth configuration to fluidically isolate the cylinder from the gas manifold, the fourth configuration corresponding to a fourth rotational position of the crankshaft of the internal combustion engine, the fourth rotational position being different than the first rotational position, the second rotational position and the third rotational position, the first configuration, the second configuration, the third configuration and the fourth configuration each occurring within one combustion cycle of the internal combustion engine.
