Abstract

A servo control which adjusts the supply of combustion diluent (either excess air or EGR) upwards until the statistical variation of flame speed achieves a set limit. The system is intended as a control coefficient input to an automatic control system capable of more rapid dynamic response than the roughness controller itself. For engines characterized by ex­ ceptional homogeneity and in-cylinder flow control, control of flame speed variability up to set limit nearly minimizes NOX emissions and very nearly optimizes fuel efficiency at all engine speeds and loads. Two «measures» of flame speed are dis­ closed, first peak blowdown pressure in the exhaust, and sec­ ond, the ionization breakdown voltage of an additional spark fired a specified number of crank angles after the ignition spark.
