Adaptive dilution control system for increasing engine efficiencies and reducing emissions

摘要

An adaptive dilution mixture control system for internal combustion engines including an apparatus for measuring a combustion force within a combustion chamber communicating with an apparatus for calculating the real-time work output of the engine from the measured combustion force, and an apparatus for controlling the variable dilution of the fuel-air mixture delivered to the combustion chamber to achieve a desired work output, the controlling apparatus responsive to the real-time work output. The apparatus for controlling the variable fuel-air mixture dilution includes a compensator for comparing the real-time work output and other engine parameters to an adaptive optimizing control model, and calculating the desired work output. Also included is a fuel injection system, and an exhaust recirculation valve to vary the dilution of the fuel-air mixture to achieve the desired work output. The adaptive optimizing control model is adapted to change over time based on a change in engine conditions.
