Title: Innovations of Yuji Sasaki

Introduction

Yuji Sasaki is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of fuel injection technology, holding a total of four patents. His work primarily focuses on enhancing the efficiency and accuracy of common rail fuel injection systems.

Latest Patents

One of Yuji Sasaki's latest patents is the "Common rail fuel injection control device." This invention computes a base duty equivalent to a base target opening degree of a metering valve and a correction coefficient based on the engine operation state. It adds the value obtained by multiplying an oscillation duty, which oscillates periodically, by the correction coefficient to the base duty, ultimately determining the final duty equivalent to a final target opening degree of the metering valve.

Another significant patent is the "Filter processing device for detecting values of common rail pressure and common rail fuel injection control device." This device reads detected values of common rail pressure within crank angle periods that are not more than half of a pumping cycle of a supply pump. The values detected within one pumping cycle preceding a reading time are averaged during each of the reading times. The resulting value is used as a common rail pressure after averaging processing, which serves as a representative or control value of the actual common rail pressure. This innovation allows for higher accuracy in the feedback control of common rail pressure.
