Title: Innovations of Yuri Sakamoto
Introduction
Yuri Sakamoto is a notable inventor based in Kariya, Japan. She has made significant contributions to the field of engineering, particularly in the automotive industry. With a total of 2 patents, her work focuses on enhancing fuel supply systems and exhaust gas purifying systems.
Latest Patents
One of her latest patents is the "Relief valve determination device for high-pressure fuel supply system." This invention involves an estimation unit that predicts fuel pressure on the discharge side of a high-pressure pump. It does this by analyzing the amount of fuel injected through a fuel injection valve when the detected fuel pressure drops from a higher to a lower status. The determination unit concludes that the relief valve is open based on the behavior of both the estimated and detected fuel pressures.
Another significant patent is the "Deterioration-determination apparatus for exhaust gas purifying system." This device employs a main feedback control using an upstream sensor's output and a sub-feedback control based on a downstream sensor's output. By inputting a specified fuel disturbance and measuring the downstream sensor's output, the system derives a characteristic value. This value is crucial for determining whether the purifying capacity of the exhaust gas purifying system, which includes the catalyst and both sensors, has deteriorated.
