Title: **Makoto Adegawa: Innovating Valve Position Detection in Internal Combustion Engines**
Introduction
Makoto Adegawa is an accomplished inventor based in Kawasaki, Japan, known for his significant contributions to the field of internal combustion engine technology. With three patents to his name, Adegawa has focused on enhancing the functionality and efficiency of valve mechanisms in engines.
Latest Patents
Adegawa's latest innovations include two patents for a valve position detector. The first patent describes a mechanism wherein a poppet valve moves up and down within a valve operating system of an internal combustion engine. The invention incorporates a cylindrical fixed electrode attached to a support plate on the cylinder head, while a cylindrical moving electrode is linked to the lower surface of a valve spring retainer, connecting to the poppet valve through a cotter. This setup enables the detection of valve position by measuring variations in electrostatic capacity during the engine's operation, resulting in precise voltage readings.
The second patent further refines this idea by utilizing a fixed electrode supported on the cylinder head and a moving electrode carried by the poppet valve. This version emphasizes a ground connection in the circuit, enhancing the accuracy of valve position detection by assessing changes in electrostatic capacitance as the valve operates during the firing sequence.
