Title: Munehiro Tabata: Innovator in Diesel Engine Technology
Introduction
Munehiro Tabata is a notable inventor based in Isehara, Japan. He has made significant contributions to the field of diesel engine technology, particularly in the area of diesel particulate filters. With a total of 3 patents to his name, Tabata's work focuses on improving the efficiency and effectiveness of diesel engines.
Latest Patents
One of Tabata's latest patents involves a regeneration device for diesel particulate filters. This device is designed to trap particulates in exhaust gas discharged from a vehicle's diesel engine. It features a condition detecting sensor that monitors the state of the diesel particulate filter, a vehicle speed sensor that tracks the speed of the vehicle, and a controller that stores a map defining a predetermined running region of the diesel engine where filter regeneration is possible. The controller is programmed to adjust the diesel engine's running point to maintain vehicle speed while ensuring it lies within the predetermined running region. Additionally, it controls the engine rotation speed and the speed ratio of the automatic transmission based on the maintained vehicle speed.
Another patent focuses on the regeneration of the diesel particulate filter itself. This filter captures particulate matter from the engine's exhaust gas. The regeneration process involves burning the trapped particulate matter by raising the filter's temperature. When specific regeneration conditions are met, the controller increases the exhaust gas temperature to a target level and burns the trapped matter. If the engine rapidly decelerates during this process, the controller adjusts the exhaust gas temperature to prevent the filter from exceeding its upper temperature limit.
