Title: Innovations by Kimitoshi Tsuji: A Journey through Hybrid Vehicles and Valve Gear Technology
Introduction: Kimitoshi Tsuji, an inventive mind hailing from Susono, Japan, has made significant contributions to automotive technology, particularly in hybrid vehicles and internal combustion engine components. With a remarkable portfolio of 21 patents, Tsuji stands out as a notable inventor in the industry.
Latest Patents: Two of Tsuji's latest patents showcase his commitment to innovation and efficiency in vehicle design. The first is a hybrid vehicle that excels in acceleration response while minimizing pumping loss. This vehicle incorporates a unique mechanism where, upon an engine combustion stop demand, the engine is rotated associatively by executing a fuel cut-off operation. Additionally, it controls the generator's speed to maintain the engine at a predetermined speed, all while ensuring that the intake and exhaust valves remain completely closed.
The second patent revolves around a valve gear specifically designed for internal combustion engines. This innovation allows for the conversion of a motor's rotational motion into linear motion through a cam. The system ensures that the intake and exhaust valves of a cylinder are opened and closed in sync with this linear movement. The motor control apparatus is advanced, enabling the motor to operate in a rocking drive mode, changing the rotation direction of the cam during the valve lift. This makes the mechanism more responsive, as the cam starts rotating just before the valve begins to lift.
Career Highlights: Tsuji's career has been significantly shaped by his work with prestigious automotive companies. Notably, he has been associated with Toyota Motor Corporation, where he refined his skills in automotive engineering. Additionally, Tsuji contributed his expertise to Denso Corporation, further enhancing his repertoire in innovative automotive technologies.
Collaborations: Throughout his career, Tsuji has collaborated with esteemed colleagues, including Yasushi Kusaka and Toshiaki Asada. These partnerships have played a crucial role in fostering a collaborative environment that is often essential for technological advancements in the automotive sector.
Conclusion: Kimitoshi Tsuji's inventive spirit and dedication to improving vehicle technology position him as an influential figure in the industry. With his notable patents, including advancements in hybrid vehicle capabilities and internal combustion engine performance, Tsuji continues to contribute to the evolution of automotive innovation, leaving a lasting impact on the future of transportation.
