Title: Daijiro Nakamura: Innovator in Occlusion Diagnosis Technology

Introduction

Daijiro Nakamura is a prominent inventor based in Wako, Japan. He has made significant contributions to the field of automotive technology, particularly in the area of occlusion diagnosis devices. With a total of five patents to his name, Nakamura's work has advanced the understanding and functionality of fuel-vapor sealing systems.

Latest Patents

Nakamura's latest patents include an innovative occlusion diagnosis device. This device executes occlusion diagnosis of a vent passage with high accuracy based on an estimated value of the volume of a sealed space. The diagnosis unit determines whether the vent passage is suspected of being occluded by comparing the estimated volume to a predefined volume threshold. If the estimated volume is equal to or less than the threshold, the device indicates a potential occlusion. Conversely, if the estimated volume exceeds the threshold, it confirms that the vent passage is not occluded. Additionally, he has developed a blockage detection device and method that operates by opening a purge valve while a negative pressure pump is in action. This device calculates gas information based on internal pressure variations, allowing for effective blockage detection in a vent line.
