With a total of 3 patents to his name, Okayasu's work reflects a commitment to innovation and environmental sustainability.

Latest Patents

One of Kouji Okayasu's latest patents is an exhaust emission control system and method for internal combustion engines. This system includes a filter in the exhaust system designed to collect particulates from exhaust gases. The engine control unit (ECU) performs post-injection, adding fuel into the combustion chamber after the combustion stroke to regenerate the filter. A vehicle speed sensor monitors the travel distance, allowing the ECU to calculate a post-injection allowable amount that increases with the detected travel distance. The system inhibits post-injection when the allowable amount reaches a predetermined threshold.

Another significant patent is the exhaust gas temperature sensor inspecting apparatus. This invention involves a temperature sensor located in the engine's exhaust system. It determines whether the conditions for inspecting the temperature sensor are met based on the current engine load range. The time required for the exhaust system temperature to reach an appropriate value for checking the sensor is calculated according to the engine's water temperature. The output of the temperature sensor is then evaluated to ensure its normal functioning.
