The first oxygen sensor is resistive-based, and responds relatively faster to changes in the temperature and/or composition of the exhaust gas. The second oxygen sensor is voltaic-based or ampometric-based, and responds relatively slower to changes to the temperature and/or composition of the exhaust gas. When the temperature and/or composition of the exhaust changes rapidly but transiently due to a combustion misfire event, the different response rates of the first and second combustion signals allows for the combustion misfire event(s) to be detected. Either and/or both oxygen sensors may be used to control the engine in a conventional fashion."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sensing combustion misfire events in engines by comparing signals derived from two different types of oxygen sensors","description":"Method and apparatus for monitoring and/or detecting combustion misfire events in periodic combustion processes in internal combustion engines, using combustion signals derived from a first oxygen sen","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10526990","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.
