Abstract
Direct injection stratified charge gasoline engines are becoming increasingly popular due to their potential for improved fuel economy and emissions. However, the benefits are restricted to low speed and load conditions due to the large air requirements during stratified operation. With boost, the air flow can be increased, extending the stratified operating regime and potentially the fuel economy and emissions benefits as well. This study assesses the feasibility of this technology using a variable geometry turbocharger and a supercharger as boost devices. The effect of boost on fuel economy, delivery of recirculated exhaust gas, and exhaust gas temperature are considered.
