  • Patent number: 10738674
    Abstract: An apparatus and method for improving warm-up of a catalytic aftertreatment device is disclosed in which the flow to a catalyst brick is controlled using a flow control device so as to restrict the flow of exhaust gas to only a central core of the catalyst brick when rapid heating of the catalyst brick is desired to reach a light-off temperature and to otherwise allow the flow of exhaust gas to the entire front face of the catalyst brick. By restricting the area of the catalyst brick to which exhaust gas can flow the energy density of the exhaust gas flowing to the central core is higher than it is when there is no restriction of flow thereby reducing the time needed to warm-up the catalyst brick to a minimum light-off temperature.

    Abstract: The present disclosure relates to an energy recovery system for a vehicle powered by an engine. The energy recovery system includes a thermoelectric module which is interfaced with a heat source of the vehicle. The heat source generates waste heat. Further, the waste heat provides a high temperature heat source for the thermoelectric module. A low temperature heat source is also interfaced with the thermoelectric module. A temperature difference between the high temperature heat source and the low temperature heat source generates thermoelectric power. A controller is configured to control a parameter of the engine to maintain an optimal value of the temperature difference between the high temperature heat source and the low temperature heat source.

  • Patent number: 8984864
    Abstract: An exhaust system for treating exhaust gas from an internal combustion engine is disclosed. The system comprises a three-way catalyst (TWC), a fuel reformer catalyst located downstream of the TWC, and a fuel supply means located upstream of the fuel reformer catalyst. The exhaust gas is split into two portions. The first portion of the exhaust gas bypasses the TWC and contacts the fuel reformer catalyst in the presence of fuel added from the fuel supply means, and is then recycled back to the engine intake. The second portion of the exhaust gas is contacted with the TWC and is then utilized to heat the fuel reformer catalyst before being expelled to atmosphere. The exhaust system allows for maximum heat exchange from the exhaust gas.
