Title: Innovations by Hiroyuki Ishikawa
Introduction
Hiroyuki Ishikawa is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of internal combustion engine technology, holding a total of four patents. His work focuses on enhancing the efficiency and effectiveness of exhaust gas purification systems.
Latest Patents
One of Ishikawa's latest patents is an exhaust gas purification device for internal combustion engines. This device includes an exhaust gas after-treatment system that features an oxidation catalyst and a diesel particulate filter (DPF). The system is designed to inject fuel into the oxidation catalyst and includes a control unit that manages the regeneration of the filter. The control unit assesses whether the filter is in a state suitable for regeneration and halts the process if necessary until optimal conditions are met.
Another significant patent is a diesel particulate filter system that aims to reduce clogging and improve convenience. This system includes an estimator for the accumulated particulate matter (PM) in an idle state. It also features a long low idle forced regeneration unit that automatically performs regeneration of the DPF when the estimated PM quantity exceeds a predetermined threshold. This innovative approach allows for the regeneration of the filter even while the vehicle is in motion.
