Latest Patents: Ishikawa's latest patents showcase his expertise in engine intake systems. One notable patent is the "Intake Apparatus for Internal Combustion Engine," which features a unique configuration that divides air distribution into two cylinder groups. This design ensures that not all adjoining cylinders fire consecutively, optimizing the combustion process. The intake passage incorporates an upstream passage that is partitioned into two separate downstream passages connecting to the respective cylinder groups. A pivotal throttle valve is positioned to extend the path of each upstream passage when the throttle valve is fully open.
Another patent titled "Engine Induction System" describes an innovative induction mechanism for V-shaped engines. This system includes individually extending intake runners from each bank of cylinders, designed to converge at their upstream ends. Connected to a junction at a further upstream position, these common intake passages optimize the engine’s induction efficiency across a wider range of operating speeds. Additionally, a valve within the communicating passage allows for engine speed regulation, enhancing the overall performance of the engine while reducing its size.
