Title: The Innovations of Hideki Yukumoto
Introduction
Hideki Yukumoto is a prominent inventor based in Kariya, Japan. He has made significant contributions to the field of engine control technology, holding a total of 7 patents. His work focuses on improving engine performance and efficiency through innovative control systems.
Latest Patents
One of Yukumoto's latest patents is a knock control apparatus for engines. This apparatus features a knock sensor that detects vibrations within the engine. It determines the occurrence of knock using various processes, including statistical analysis, waveform processing, and FFT (Fast Fourier Transform) techniques. By employing multiple methods, the apparatus enhances the accuracy of knock detection. Additionally, it learns a corrective value during stable engine conditions, which is then utilized to adjust ignition timing during transitional conditions, thereby reducing knock effectively.
Another notable patent is an engine control apparatus and method that incorporates cylinder-charged air quantity correction through intake and exhaust valve operation. This method begins by determining a basic cylinder-charged air quantity using first-order delay processing of the intake air quantity per rotation. It then computes an estimated change in the cylinder-charged air quantity based on engine speed and intake valve timing. By applying a second-order delay processing, the method accurately adjusts the actual cylinder-charged air quantity, accommodating changes in intake valve timing.
