There's an old saying in engine tuning that when adjusting the mixture of your engine you can be too rich a bunch of times, but only too lean once. With that in mind, determining the air-fuel ratio ...
Better fuel economy, reduced exhaust emissions and better drivability strongly depend on precise control of airfuel ratio (AFR) during both steady and transient engine operations. A discrete, ...
This paper describes the results of a study that examined the mechanism of phased perturbation as an emissions control technique. Phased perturbation involves independently controlling the fuel ...
