Title: Masaaki Shinojima: Innovating Valve Timing Control Mechanisms
Introduction
Masaaki Shinojima, an accomplished inventor based in Kariya, Japan, has made significant contributions to the automotive industry. With a total of four patents to his name, Shinojima's work focuses on enhancing internal combustion engine performance through advanced valve timing control mechanisms.
Latest Patents
Shinojima's latest innovations include a patented valve timing control mechanism for internal combustion engines. This mechanism precisely manages the rotational phase difference between an engine crankshaft and camshaft, utilizing a closed-loop feedback system. Notably, this feedback system possesses a learning capability, allowing it to adjust and converge the phase difference toward a target value based on the operational state of the engine. The learning process employs retaining outputs to fine-tune the actuation degree of the phase adjustment mechanism, thereby optimizing engine performance.
Another remarkable patent by Shinojima is the valve timing control system for engines. This system aims to achieve highly reliable feedback control of the valve timing by generating three reference signals from the crankshaft and an equal number of cam signals from the camshaft. To account for phase differences caused by installation variances of pulse inductors, these deviations are stored as compensation values in memory. During signal detection, appropriate compensation values are utilized to ensure precise control of the crankshaft and camshaft's rotational phases, aligning them with desired valve timing targets.
