Latest Patents

One of Oota's latest patents is a catalyst deterioration recovery device. This device is designed to restore the efficiency of a platinum catalyst used for engine exhaust purification that has temporarily deteriorated due to oxidation. The device applies a stoichiometric air-fuel ratio or a richer air-fuel ratio to the engine. It detects the engine running condition and the decrease of catalyst oxidation, setting a recovery treatment temperature based on the degree of oxidation. By determining whether the running condition is within the suitable range, the device performs recovery treatment efficiently, minimizing fuel costs and improving exhaust gas composition.

Another significant patent is a fuel gauge system for indicating the amount of mixed fuel. This system includes multiple devices that work together to visually indicate the amount of mixed fuel in a container, detect the real amount of fuel, and determine the mixing ratio of compositions. It also judges whether the real amount is less than a critical effective amount and controls the visual indication accordingly. This innovation enhances the management of fuel resources and ensures optimal performance.
