Title: Innovations by Makoto Ohtake
Introduction
Makoto Ohtake is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of automotive technology, particularly in the area of particulate filter regeneration. With a total of 4 patents to his name, Ohtake's work has had a meaningful impact on vehicle emissions control.
Latest Patents
One of Ohtake's latest inventions is a particulate filter regenerating device. This device is designed to regenerate a particulate filter that collects particulate matter from engine exhaust gas. It is specifically configured to prevent the temperature of the particulate filter from exceeding an allowable limit during the regeneration process. This is particularly important when the estimated quantity of accumulated particulate is lower than the actual amount due to variations in estimation. The device intelligently reduces the temperature rise of the exhaust gas when it detects that the temperature of the particulate filter is approaching its maximum allowable temperature.
Another aspect of his particulate filter regenerating device is its ability to prevent uneven distribution of particulate matter, which can occur if the regeneration process is interrupted. The device increases the frequency of regeneration by determining the optimal time to initiate the process based on the exhaust gas temperature and the quantity of accumulated particulate matter. The regeneration is achieved by raising the exhaust gas temperature to combust the accumulated particulate matter effectively.
Career Highlights
Makoto Ohtake is currently employed at Nissan Motor Company Limited, where he continues to innovate and develop technologies that enhance vehicle performance and reduce emissions.
