Title: Tetsuya Asami: Innovator in Exhaust Gas Purification Systems

Introduction

Tetsuya Asami is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of exhaust gas purification systems, particularly for diesel engines. With a total of 2 patents to his name, Asami's work focuses on improving environmental standards and engine efficiency.

Latest Patents

Asami's latest patents include an innovative exhaust gas purification system designed to enhance the performance of diesel engines. The first patent describes a diesel particulate defuser (DPD) that collects particulate matter (PM) in exhaust gas. When the PM in the DPD reaches a predetermined level, the system increases the exhaust gas temperature of the diesel engine through exhaust pipe injection, allowing for automatic regeneration of the DPD. This system also features a PID control mechanism that adjusts the exhaust pipe injection amount based on the difference between the detected exhaust gas temperature and a target regeneration temperature.

The second patent focuses on an exhaust gas purification system specifically for high altitude use. This system determines the upland full-load injection quantity based on atmospheric pressure and engine speed while the vehicle is in motion. During the regeneration mode, it calculates an upland drive regeneration injection quantity by adjusting the full-load injection quantity to accommodate post-injection requirements. The system gradually decreases the injection quantity as the vehicle transitions from normal drive mode to regeneration mode, ensuring efficient operation.
