Latest Patents
One of Uchiyama's latest patents is a fuel injection strategy for four-cycle engines. This invention includes a combustion chamber designed with a substantially flat surface, allowing for a larger area where fuel can collect and evaporate. The injection strategy involves two stages; the first stage begins before the top-dead center and halts before reaching a range that produces smoke. The second stage commences after this range and concludes when the intake valve reaches its maximum lift.
Another significant patent is for an in-cylinder injection gasoline engine. This invention features various combustion chamber configurations for direct-injected engines. The fuel injectors are designed to inject at least two fuel patches in circumferentially spaced locations. The fuel is directed into a cavity arrangement in the piston head, which guides it upward toward a pair of circumferentially spaced spark plugs, ensuring complete combustion within the combustion chamber.
