Abstract
Developing engine calibrations to help achieve improved fuel economy, emissions and performance has become an increasingly complicated task as emission standards become more stringent and fuel economy standards become effective. A methodology was devised to project the economy that a specific vehicle could achieve over a selected driving cycle. This method can be used to determine the potential of control systems, exhaust treatment devices and drivetrain configurations to improve economy at specified emission levels. Optimum engine calibrations are defined to utilize these devices fully, from which automatic engine calibration strategies can be developed for vehicle verification.
