Latest Patents
One of Kato's latest patents is a high-pressure fuel feeding device for fuel injection engines. This invention features an outboard motor equipped with a fuel/air injection system. All major components of the fuel portion are contained within a sealed chamber, which includes a fuel drain. The conduits supplying fuel to the injectors are also enclosed within fuel-collecting conduits, preventing any fuel leakage into the atmosphere. Additionally, the air pressure supplied to the injectors is regulated, with any relieved air returned to an air inlet device that condenses fuel and returns it to a vapor separator. This innovative design is particularly suited for V-type engines, where the components are strategically positioned in the valley between the cylinder banks.
Another notable patent is a water injection propulsion device. This invention includes two embodiments of jet-propelled watercraft that feature improved electrically powered trim adjustments. In one embodiment, the trim adjustment allows for pivotal movement of the discharge nozzle of the jet propulsion unit. In the other, the electric power operates a trim plate of the hull that extends beneath the jet propulsion unit, enhancing the overall performance of the watercraft.
