  • LOW EMISSIONS, HIGH WORKING CAPACITY ADSORBENT AND CANISTER SYSTEM
    Publication number: 20240207813
    Abstract: The present description provides high working capacity adsorbents with low DBL bleed emission performance properties that allows the design of evaporative fuel emission control systems that are lower cost, simpler and more compact than those possible by prior art. Emission control canister systems comprising the adsorbent material demonstrate a relatively high gasoline working capacity, and low emissions.
    Type: Application
    Filed: December 21, 2022
    Publication date: June 27, 2024
    Inventors: Laurence H. Hiltzik, James R. Miller, Roger S. Williams, Cameron I. Thomson, Michael G. Heim, Emma M. Card, Stephan Charles Cronin
