The diagnosis section is adapted to diagnose that the sensor is abnormal when only one of a first condition and a second condition is satisfied. The first condition is that the purification rate η calculated by the calculation section is greater than or equal to a reference purification rate. The second condition is that the detected value Cur acquired by the acquisition section is greater than or equal to a reference concentration."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Diagnostic device for urea water supply system","description":"A diagnostic device for a urea water supply system having a sensor for detecting a concentration of urea water includes an acquisition section that acquires a detected value of the sensor, a calculati","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9708952","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.
