Abstract
Herein disclosed is a combustion cell adapted for an internal combustion engine, comprising i) a hydraulic engine valve actuation portion capable of providing a selection of two different and stable engine valve lift (i.e., open) positions per engine valve or per coupled engine valves and ii) a fuel injection portion capable of providing a selection of comprising i) a hydraulic engine valve actuation portion capable of providing two stable engine valve lift positions and ii) a fuel injection portion capable of providing a selection of one, two or three injection pressure levels for injection fuel.The combustion cell provides more flexibility in control of incoming intake air, outgoing exhaust gas, and/or incoming injection fuel relative to an engine combustion chamber so as to better match engine operating conditions that may change over time.
