Abstract
A system and method for improving engine emissions is described. In one example, engine emissions may be improved via increasing rotational resistance of a turbocharger while a temperature of an exhaust after treatment device is less than a threshold temperature. The system and method may reduce an amount of time for the after treatment device to reach an operating temperature.
