Latest Patents

One of Hisamoto Aihara's latest patents is a fuel injection apparatus for an internal combustion engine. This innovative apparatus features at least one fuel injection valve and an annular or ring-shaped electrode that encircles the injected fuel. A high voltage generator creates an electric field between the electrode and the fuel injection valve, which is connected to the ground. This design allows electrified fuel particles to be finely atomized, preventing them from adhering to the surrounding wall, thereby improving the engine's operation, starting characteristics, and transient response.

Another significant patent by Aihara is for an internal combustion engine with direct fuel injection. This engine comprises at least one combustion chamber equipped with a fuel injection valve. A charging electrode is positioned in the combustion chamber near the fuel injection valve and is supplied with a high DC voltage from a voltage source. This setup charges the particles of fuel injected from the valve, promoting better dispersion.
