Title: Yutaka Hayakawa: Innovator in Combustion Detection Technologies
Introduction
Yutaka Hayakawa is a notable inventor based in Okazaki, Japan. He has made significant contributions to the field of internal combustion engine technology, holding two patents that focus on improving the detection of abnormal combustion.
Latest Patents
One of his latest patents is the "Abnormal Combustion Detection Apparatus for Internal Combustion Engine." This invention aims to provide a technology that enables accurate detection of abnormal combustion, such as pre-ignition and knocking, in spark ignition internal combustion engines with multiple cylinders. The apparatus enhances detection accuracy by adjusting the determination threshold based on the peak vibration intensity and engine speed when abnormal combustion is detected.
Another significant patent is the "Abnormality Detection Device for Exhaust Gas Recirculation Apparatus." This device performs abnormality detection concerning an EGR valve while minimizing the influence of the size relationship between intake and exhaust pressures. The Electronic Control Unit (ECU) processes intake pipe pressure values and executes Fast Fourier Transform (FFT) on the output waveform from the intake pressure sensor. It determines whether the amplitude size of the extracted pulse exceeds a threshold value, indicating a potential abnormality in the EGR valve.
