Latest Patents
One of Handa's latest patents involves a four-stroke internal combustion engine. This design features cylinders of noncircular cross-section, where the cylindrical curve is generated at a preselected constant outwardly normal distance from a closed curve. The closed curve is defined by two spaced points on a major axis of symmetry of the cylinder, with two continuously curved portions extending between these points and curving outwardly from the major axis. This design ensures a continuous change of curvature without discontinuity, which aids in mass production and cutter life. The patent also discloses various intake and exhaust port arrangements, illustrating four intake ports and four exhaust ports on opposite sides of the major axis of symmetry. In one embodiment, the outermost ports are smaller and positioned closer to the major axis of symmetry. In another embodiment, the valves are oriented such that their stems point to the centerline of the associated camshaft for direct actuation.
