Akira Shibanaka is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of internal combustion engines, particularly with his innovative designs that enhance engine efficiency.

Latest Patents

Shibanaka holds a patent for a "Multiple cylinder internal combustion engine having mixture cut off means." This invention features a multiple cylinder engine equipped with an intake passage for each cylinder. The design includes shut-off valves in the intake passages leading to selected cylinders downstream of the throttle valve. During idling operation, these valves close to ensure that the combustible mixture is fully supplied to the remaining cylinders, thereby increasing the mixture charge. Additionally, when the shut-off valves are closed, air is supplied to the selected cylinders, which raises the peak pressure. The air supply is cut off during deceleration to prevent the weakening of the engine-brake effect.
