Title: The Innovative Contributions of Shinichiro Kikuoka

Introduction

Shinichiro Kikuoka is a prominent inventor based in Nishikamo-gun, Japan. He has made significant contributions to the field of internal combustion engines, holding a total of 14 patents. His work focuses on enhancing the efficiency and functionality of engine components through innovative mechanisms.

Latest Patents

One of Kikuoka's latest patents is a variable valve mechanism for internal combustion engines. This mechanism includes multiple swing members and a variable device that displaces a control shaft. This design allows for simultaneous adjustment of valve lifts across several swing members through the meshing of helical splines. The mechanism features a first swing member designated for a specific cylinder and a second swing member for other cylinders, with varying helix angles to optimize performance. Another notable patent is a valve timing controller for internal combustion engines. This invention sets the cam profile based on the relationship of a stop position of a vane rotor at its most retarded phase. The design ensures that a communication passage opens in a second retardment chamber when the camshaft is at a neutral position, minimizing torque applied from the cam to the camshaft.
