Title: Kazuaki Nemoto: Innovator in Valve Timing Technology

Introduction

Kazuaki Nemoto is a notable inventor based in Kariya, Japan, recognized for his contributions to valve timing technology. With a total of three patents to his name, he has made significant advancements in the automotive industry, particularly in the development of devices that enhance engine performance.

Latest Patents

One of Nemoto's latest patents is a valve timing adjusting device. This device features an intake variable valve mechanism and an exhaust variable valve mechanism. The exhaust variable valve mechanism includes an exhaust electric driving portion and an exhaust phase shifting portion that contains an input shaft. This phase shifting portion is strategically placed in the rotation transmission path between the exhaust camshaft and the crankshaft, allowing for the adjustment of the rotation phase of the exhaust camshaft. Notably, the input shaft rotates in the opposite direction of the crankshaft when advancing the rotation phase. Additionally, the phase shifting portion is designed to shift to a most advanced angle phase when the exhaust electric driving portion is de-energized or fails, ensuring optimal performance under various conditions.

Another significant patent by Nemoto is the valve timing controller. This invention includes a joint that consists of a rotation transmitting portion and a stopper portion. The rotation transmitting portion engages with a relative rotating portion in a circumferential direction. The stopper portion is capable of abutting the relative rotating portion to restrict its axial position. This design prevents sliding movement between the relative rotating portion and the stopper portion, thereby enhancing power transmission efficiency and reducing abrasive wear.
