  • Systems and methods for controlling exhaust flow through an aftertreatment device
    Patent number: 9238468
    Abstract: Various methods and systems are provided for a system for an engine. In one example, the system includes an exhaust passage through which exhaust gas is configured to flow from the engine. The system further includes an aftertreatment system disposed in the exhaust passage, the aftertreatment system including an aftertreatment device and a bypass with a bypass control element, the bypass control element adjustable to reduce exhaust gas flow through the aftertreatment device during tunneling operation.
