Introduction

Yukio Noda is a notable inventor based in Wako, Japan, recognized for his contributions to the field of internal combustion engine control. With a total of 5 patents to his name, Noda has made significant advancements that enhance engine performance and efficiency.

Latest Patents

Noda's latest patents include a control apparatus for internal combustion engines and an air-fuel ratio control system. The control apparatus features a diagnosis device that includes a determination section and an exhaust flow rate calculator. This system calculates an exhaust flow rate that accurately reflects the volume flow of exhaust gas. Additionally, it employs a filter to extract a 0.5th-order frequency component of engine speed from the air-fuel ratio signal. The integrator accumulates the filtered signal over a predetermined period to compute an integration value, which is then corrected to determine cylinder-to-cylinder air-fuel ratio imbalances.

The air-fuel ratio control system incorporates an oxygen concentration sensor in the exhaust system, which provides feedback to an ECU for maintaining the desired air-fuel ratio. The system detects the activated state of the sensor and limits the correction of the air-fuel ratio based on this state, ensuring optimal engine performance.
