Abstract

An engine system that delivers torque to a driveline of a vehicle includes an internal combustion engine (ICE), a manifold, an exhaust gas recirculation (EGR) circuit, an electric turbine (eTurbine) and a controller. The EGR circuit has an EGR valve that selectively moves between open and closed positions. The eTurbine is driven by an electric motor and is configured to deliver air away from the manifold. The controller determines an ICE start request and, based on the ICE start request, sends a signal to the EGR valve to open thereby fluidly connecting the manifold and the eTurbine. The controller sends a signal to the eTurbine to rotate and move air out of the manifold through the EGR circuit. The eTurbine is used to deplete air in the manifold before starting the ICE. As a result, a reduction in fuel used and therefore a reduction in emissions at startup is achieved.
