Title: The Innovative Mind of Kouzi Ohara
Introduction: Kouzi Ohara is a distinguished inventor based in Aichi-ken, Japan, recognized for his significant contributions to the field of internal combustion engine technology. With a total of six patents to his name, Ohara has developed advanced devices and methods that enhance engine performance by accurately determining and managing engine knock.
Latest Patents: Ohara's latest innovations are centered around an internal combustion engine knocking judging device and a knocking judging method. The engine's electronic control unit (ECU) is designed to calculate a 15-degree integrated value, which integrates vibration intensity across six crank angle ranges. The device detects changes in this integrated value between ignition cycles, specifies ranges with notable changes, and identifies crank angles with intensities greater than neighboring angles. A coefficient of correlation is then calculated to compare detected vibrations with a knock waveform model. If this coefficient exceeds a specified threshold, the system concludes that knocking has occurred. Additionally, his knock determination device assesses knock intensity by contrasting the detected vibration waveform with a stored knock waveform model, determining engine knock based on predefined reference values.
Career Highlights: Throughout his career, Kouzi Ohara has been affiliated with notable companies, including Nippon Soken, Inc. and Nippondenso Co., Ltd. His work at these organizations has played a pivotal role in advancing engine technology and ensuring the development of reliable automotive solutions.
Collaborations: Ohara has collaborated with esteemed colleagues such as Katsuyuki Tanaka and Tokio Kohama, contributing to a dynamic exchange of innovative ideas and technical expertise that has expanded the horizons of engine technology.
Conclusion: Kouzi Ohara's inventive contributions, characterized by his six patents, exemplify his dedication to improving internal combustion engine efficiency and reliability. His innovative methods for determining engine knock are essential advancements that continue to influence the automotive industry, positioning him as a notable figure among contemporary inventors in Japan.
