The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing an engine control system that provides precise performance control through real-time modeling and evaluation.
Promises improved fuel economy lower emissions and better performance by providing real-time and potentially more accurate estimates of key engine parameters Requires fewer calibration tables than competing approaches which reduces engine development time and possibly engine cost Models MAC for each cylinder individually allowing each cylinder\'s fuel injection and spark to be set in accordance with its own MAC estimate Because it accounts directly for cylinder gas dynamics the model minimizes errors in MAC estimates that often occur under transient engine conditions. Measured engine parameters can be fed back to the virtual cylinder enabling it to more accurately model actual engine states. In addition to intake parameters model can calculate and control residual exhaust gas and therefore NOX emissions.
