Title: Yasuhiro Fujiwara: Innovator in Gaseous Fuel Measurement
Introduction
Yasuhiro Fujiwara is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of fuel measurement technology. His innovative work focuses on the instantaneous flow rate measurement of gaseous fuel injectors.
Latest Patents
Yasuhiro Fujiwara holds a patent for an "Instantaneous flow rate measurement instrument of gaseous fuel injector." This invention involves a gaseous fuel injector that supplies gaseous fuel from a compressed gas cylinder into a measuring portion thin tube. The pressure change in the tube is measured by a pressure measuring device through a small hole provided in the thin tube. An extension thin tube is included to remove the influence of reflected waves on the downstream side of the measuring portion thin tube. A back pressure valve is also provided at the downstream side end of the extension thin tube to uniformly increase the pressure in the tube, bringing it close to the actual environment in the engine cylinder. Additionally, a tapered-shape nozzle is arranged in the measuring portion thin tube. The pressure measured by the pressure measuring device is transduced into mass flow rate in the thin tube according to a predetermined calculation formula. This allows for the measurement of the instantaneous mass flow rate of gaseous fuel injected from the gaseous fuel injector.
