Introduction

Toshihiro Nagano, an accomplished inventor based in Omiya, Japan, has made significant strides in the field of engine technology. With a total of nine patents to his name, Nagano has a proven track record of innovation that enhances engine performance and efficiency.

Latest Patents

Among his latest inventions is the "Exhaust Timing Control Apparatus for Two-Cycle Engines." This apparatus is designed to optimize engine performance across varying speed ranges. At low to medium speeds, the control valve is projected toward the cylinder by the spring's biasing force, effectively lowering the upper edge of the exhaust port. This action opens a resonance chamber, thereby boosting the engine's power. Conversely, at high speed ranges, when combustion pressure is significantly higher, the control valve retreats, enlarging the exhaust port and closing the resonance chamber to further enhance power output.

Another noteworthy patent is the "Separate Oiling Type Two-Cycle Engine." This innovative engine features a diaphragm-type float-less carburetor that incorporates a metering chamber and a needle valve. It includes a unique fuel reservoir and a fuel return port designed to prevent corrosion and clogging of vital carburetor components by ensuring that lubricating oil is continuously mixed with fuel.
