Title: Yuichi Momose: Innovator in Engine Technology

Introduction

Yuichi Momose is a notable inventor based in Nagano, Japan. He has made significant contributions to the field of engine technology, holding 2 patents that showcase his innovative approach to improving internal combustion engines.

Latest Patents

One of his latest patents is a decompressor for an internal combustion engine. This invention features a decompressor designed to start an engine using a recoil starter. The compression pressure within the cylinder is adapted to escape, allowing for a compact engine layout. The decompression valve is positioned vertically with respect to the crankshaft, preventing lateral projection from the cylinder and avoiding interference with the cowling. This design simplifies the interlocking mechanism of the decompression valve with the recoil starter. Additionally, the cam at the recoil reel is variable, allowing for adjustments based on the engine type to optimize the starting mechanism.

Another significant patent by Momose is related to a four-stroke-cycle engine. In this design, air is drawn into the crank chamber when negative pressure is built up. The air, mixed with blowby, is then led as secondary air to the exhaust gas discharge section when positive pressure is established. This mixture is burned again in the exhaust gas cleaning section, effectively cleaning the exhaust gases. The invention includes two valves to check the backflow of air while maintaining airflow from the crank chamber to the exhaust gas discharge section.
