In this way, purging of the first canister may be prioritized and completed without passing desorbed fuel vapors through the second canister, thereby reducing the amount of time needed to purge the first canister, and reducing overall emissions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for reducing airflow restriction through emissions control systems","description":"A method for a fuel system is presented, comprising directing purge air through a first fuel vapor canister but not a second fuel vapor canister based on a load of the first fuel vapor canister being ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9611814","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
