His work focuses on improving engine performance and diagnostics, showcasing his expertise and innovative thinking.
Latest Patents
One of Drexel's latest patents is related to engine synchronization. This invention provides a method for synchronizing relative engine angular position information without an absolute engine position input signal. By inducing misfires in a known engine cylinder and monitoring the misfire behavior, the system can correct the assumed engine absolute position through the application of a position offset. This method ensures accurate engine operation even in the presence of misfires.
Another significant patent by Drexel addresses misfire detection in internal combustion engines. This invention diagnoses misfires by monitoring changes in engine speed and generating an acceleration spike index for each cylinder event. The corrected acceleration spike index is then compared to misfire thresholds, allowing for the diagnosis of misfire severity based on the frequency of excursions above these thresholds.
