Title: Masashi Mizutani: Innovator in NOx Sensor Technology

Introduction

Masashi Mizutani is a prominent inventor based in Fujisawa, Japan. He has made significant contributions to the field of automotive technology, particularly in the development of systems that enhance the efficiency and reliability of emissions control.

Latest Patents

Mizutani holds 3 patents, with his latest innovations focusing on NOx sensor diagnosis and urea water temperature sensor systems. One of his notable patents is the NOx sensor diagnosis apparatus, which effectively diagnoses an NOx sensor located in an exhaust pipe. This apparatus detects the concentration of NOx in exhaust gas by utilizing a calculation value operating unit that assesses the engine's actuation state. An error determining unit identifies sensor errors when discrepancies between calculated and detected NOx concentrations exceed a set threshold. Additionally, a determination threshold value setting unit adjusts this threshold based on various environmental factors, including water cooling temperature, atmospheric pressure, and outdoor temperature.

Another significant patent is the competence diagnosis system for a urea water temperature sensor. This system is designed to prevent misdiagnosis when urea water is replenished in a urea tank. It features a urea water level condition determination unit that records the urea water level before the engine is turned off. Upon restarting, it compares the stored level with the current level to facilitate accurate diagnosis through temperature comparison, provided the level difference remains within a predetermined threshold.
