Abstract
Methods and systems are provided for adjusting flow of exhaust gas from downstream of an exhaust turbine outlet to an exhaust gas aftertreatment device inlet via a compact turbine outlet cone with adjustable swirl vanes. Exhaust flow reaching the exhaust gas aftertreatment device is adjusted based on a desired exhaust gas temperature and exhaust gas flow rate at the aftertreatment device. During cold start conditions, the swirl vanes may be closed to concentrate exhaust gas flowing towards a portion of the aftertreatment device while after attainment of aftertreatment device light-off temperature, the position of the swirl vanes may be adjusted to introduce turbulence and homogeneity to exhaust flow reaching the exhaust aftertreatment device.
