METHOD AND SYSTEM FOR EMISSIONS REDUCTION

Methods and systems are provided for coordinated operation of electric variable geometry turbocharger (e-VGT), an exhaust gas recirculation (EGR), and electric motor coupled to the e-VGT for expedited catalyst light-off. In one example, a method may include, during a cold-start, decreasing each of an opening of e-VGT vanes and an opening of an EGR valve while operating the electric motor for braking and reducing the e-VGT speed.
