Single Sensor Individual Cylinder Air-Fuel Ratio Control of an Eight Cylinder Engine with Exhaust Gas Mixing

P.E. Moraal, J.A. Cook, Jessy W. Grizzle

Open publisher page 15 citations

Abstract

This paper describes the application linear periodic control techniques to the analysis and design of an individual cylinder air-fuel ratio controller for an 8-cylinder engine. A model of the engine including exhaust gas mixing in the manifold is developed. The resulting system was determined to be nearly unobservable. The exhaust manifold was subsequently redesigned, and a successful controller implemented.
