Latest Patents

Yonekawa's latest patents showcase his ingenuity in designing fuel supply systems. One notable invention is the "Fuel Supply System with Fuel Dust Removing Structure." This system incorporates a fuel return branch connection that allows part of the fuel passing through a fuel filter to be returned to the fuel tank. By extending the connection to the tank's bottom, the system facilitates continuous filtration of the fuel, thereby improving dust removal and enhancing fuel flow efficiency. This design also contributes to better cooling of the fuel pump, effectively preventing vapor generation and promoting durability.

Another significant patent is the "Fuel Supply System for Engines with Fuel Pressure Control." In this system, Yonekawa utilizes a differential pressure sensor to measure the actual fuel pressure, which is then averaged to yield two distinct values. While one value is designated for controlling fuel pressure, the other is used to adjust pulse width. The resulting correction value is determined by the engine load and aids in fine-tuning the fuel discharge pressure from the pump.
