Abstract
Exhaust temperatures in emission control devices may be directly controlled by an intake air throttle, fuel injection timing, and exhaust pressure when an emission control device is placed between two variable geometry turbocharger exhaust turbines and coupled to a combustion engine. Such an approach may substantially raise the temperature of the exhaust aftertreatment devices in an emission control device during non-warmed exhaust conditions, leading to faster catalytic light-off.
