  • Twin turbo diesel aftertreatment system
    Patent number: 8371108
    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.
    Type: Grant
    Filed: August 4, 2009
    Date of Patent: February 12, 2013

  • Diesel Engine Aftertreatment Control Operation with Waste Heat Recovery
    Publication number: 20090107117
    Abstract: A diesel engine exhaust gas aftertreatment system is described. The system may comprise a heat transfer device comprising a first side and a second side; a heater downstream of the first side of the heat transfer device, a filter downstream of the heater; and, an exhaust path downstream of the filter leading to the second side of the heat transfer device, wherein the exhaust path is isolated from an external surface of the filter to inhibit heat transfer from the heated exhaust gas exiting the filter to the external surface of the filter.
