Parametric Variations of a Heat Balanced Engine.

Abstract

Performance of a CFR engine over a wide range of experimental conditions is reported in detail for standard spark ignition operation and for heat balanced configurations. Operating conditions were mapped for primary combustion chamber and balancing chamber volumes giving nearly constant balancing ratios for three selected compression ratios; edge gap clearance was also varied. Three secondary air modes were investigated during optimization of performance giving more than a 30% increase in output over standard S.I. operation, an improvement in ISFC of 10% at best economy, 30% at best power with CO emission decreased to less than 0.1% and UHC to less than 100 ppm. A new method of engine performance analysis, the Run Quality Index (RQI) is proposed to help evaluate the heat balanced engine and compare it to other engines.
