Latest Patents

Among Uedahira's latest patents is a groundbreaking device for clarifying exhaust gas from internal combustion engines. This innovative exhaust emission control system incorporates a monolith catalyst that features an oxygen storage agent alongside a noble metal-based three-way catalyst composed of palladium (Pd), rhodium (Rh), and platinum (Pt). Positioned upstream in the exhaust gas flow, this arrangement optimally functions with a perovskite-type double oxide located downstream, effectively managing emissions.

The specific configuration and amounts of each component—0.97 to 1.68 g/L of Pd, 0.11 to 0.2 g/L of Rh, 0.06 to 0.11 g/L of Pt, 25 to 75 g/L of the oxygen storage agent, and 5 to 15 g/L of the perovskite-type double oxide—enable reduced production costs of the noble metal-based catalysts while maintaining a high rate of exhaust emission control.

Another notable patent from Uedahira encompasses an apparatus designed for controlling the air-fuel ratio in internal combustion engines. This system manipulates the air-fuel mixture to achieve a target output from an oxygen sensor positioned downstream of the catalytic converter, depending on the engine's operating state. It also assesses the deterioration of the catalytic converter using time-series data, enhancing the reliability and longevity of the emissions management system.
