  • Multicomponent exhaust treatment system including an oxygen storage catalyst
    Patent number: 11073061
    Abstract: Methods and systems are provided for a multicomponent aftertreatment device arranged in a vehicle exhaust gas passage. In one example, a system may include an oxygen storage catalyst and an underbody trap catalyst comprising metal modified zeolite, the oxygen storage catalyst arranged upstream of the underbody trap catalyst in an exhaust passage of the vehicle.
    Type: Grant

  • Methods and systems for an exhaust aftertreatment device
    Patent number: 10634078
    Abstract: Methods and systems are provided for an aftertreatment system arranged in a vehicle underbody downstream of close-coupled aftertreatment devices, the aftertreatment system including a first aftertreatment device and a second aftertreatment device adjacent one another. In one example, the first aftertreatment device is a hydrocarbon trap and the second aftertreatment device is a three-way catalyst.

  • Hydrocarbon retaining and purging system
    Patent number: 8413433
    Abstract: Methods and systems are provided for reducing hydrocarbon emissions from an engine having a hydrocarbon retaining system. One example method comprises flowing exhaust gas over a hydrocarbon trap, the trap having a plurality of layers with different porosity and/or a different adsorptive affinity to hydrocarbon chains, and flowing hydrocarbons from a fuel tank over the hydrocarbon trap.
