Abstract
Gasoline engines that employ high levels of exhaust gas recirculation (EGR) may suffer from slow torque transients during tip-in and tip-out maneuvers. This is due to the residual EGR present in the engine intake manifold. In order to fill these torque holes, we explore the use of a belted alternator starter (BAS) mechanism. The BAS supplements the torque provided by the engine. In the present work, we investigate the operating modes and show that the power and torque levels of the BAS are adequate to add the necessary driveline torque for acceptable tip-in response.
