Yukinori Nose is a prominent inventor based in Shizuoka, Japan. He has made significant contributions to the field of outboard motor technology, holding a total of 8 patents. His innovative designs have enhanced the performance and efficiency of marine engines.

Latest Patents

One of his latest patents involves an outboard motor that features an exhaust passage designed to discharge exhaust gases generated in a V-type engine into water from an exhaust opening. This exhaust passage includes first and second branch passages connected to cylinders and arranged inside a V-shaped line. Additionally, it has a first upstream collecting passage connected to each of the first branch passages, a second upstream collecting passage connected to each of the second branch passages, and a downstream collecting passage that connects the first and second upstream collecting passages. Notably, a portion of the downstream collecting passage is positioned outside the cylinder heads of the V-type engine.

Another significant patent pertains to an eight-cylinder engine that fires cylinders at intervals corresponding to a crank angle of 90 degrees. The firing occurs in four cylinders of each of the first and second banks at uneven intervals. In pairs of cylinders where firing is conducted consecutively at an interval corresponding to a crank angle of 90 degrees, the central angle of the exhaust cam for one cylinder is larger than that of the other cylinder. This innovative design optimizes engine performance and efficiency.
