Latest Patents
Hohkita holds a patent for a "Method and apparatus for attenuating fuel pump noise in a direct injection internal combustion chamber." This invention addresses the challenge of fuel pump noise by suspending the direct injection fuel nozzle from a fuel rail, thereby preventing direct metal-to-metal contact with the engine block. Additionally, the design incorporates spaced-apart seals that help equalize longitudinal pressure on the nozzle during operation. To further mitigate noise from fuel pump pulsation, the system may include enlarged diameter fuel reservoirs and/or a restricted orifice positioned fluidly in series between the fuel pump and the direct injection nozzle.
