Latest Patents
Franz A. Lieder holds a patent for an "Idle Air Control System Diagnostic." This invention focuses on diagnosing idle RPM faults in internal combustion engines. The system utilizes RPM, engine timing, and intake airflow measurements to detect faults and verify the idle air control system as the source of the issue. The diagnostic process includes measuring engine idle RPM and comparing it with a commanded idle RPM. If the measured RPM falls within a predetermined range, an idle RPM fault is identified, prompting further testing. The non-intrusive test measures intake airflow against a predetermined value, while the intrusive test assesses variations in intake airflow in response to throttle-bypass airway pintle movements. This innovative diagnostic method ensures accurate identification of faults within the idle air control system.
