  • Implementing variable valve actuation on a diesel engine at high-speed idle operation for improved aftertreatment warm-up
    Patent number: 11359564
    Abstract: Increasing engine idle speed, combined with modulating the timing of the exhaust valve during idling, increases heat transfer from the engine to aftertreatment systems to reduce the time required for the aftertreatment system to reach a minimum temperature for efficient operation. The resultant increases in heat transfer include an increase of at least 30% in the flow rate of exhaust gases and an increase of exhaust temperature by at least 25° C.
    Type: Grant
    Filed: March 30, 2021
    Date of Patent: June 14, 2022
    Assignee: Purdue Research Foundation
