Latest Patents

Walters' latest patents include a "Method and apparatus for diagnosing faulty cylinders in internal combustion engines." This invention provides a systematic approach to identifying faulty cylinders by analyzing the instantaneous angular velocity of the engine shaft. By computing a Percent Power Contribution (PPC) parameter, the method can indicate a faulty cylinder when the value is significantly less than zero. Additionally, an Average Energy Percent (AEP) parameter is calculated to assess the previous cylinder in the firing order. These parameters can be utilized independently or together to diagnose both continuous and transient engine faults, with results displayed on a monitor for operator awareness.

Another significant patent is the "Method and apparatus for feature extraction from internal combustion." This invention focuses on real-time extraction and analysis of features from ignition waveforms. It includes a sampling device and processor that detect anomalies by comparing waveform features against fixed thresholds. The ability to report anomalies as they occur allows for timely diagnosis of transient events, enhancing engine performance monitoring.
