MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202647092366 A) filed by Kabushiki Kaisha Toyota Jidoshokki on July 30, 2026, for Exhaust Purifying Device For Internal Combustion Engine And Method For Controlling Same.
Inventors include Tsutsui Yuto; Takagi Akihiro; and Kawachi Takashi.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: An engine ECU (100) executes a fuel addition process using a fuel addition valve (80) before executing a DPF regeneration process. For the fuel addition process, after implementation of refueling, when an exhaust temperature reaches a temperature (T2) lower than a temperature (T1pset) preset as a fuel addition implementation temperature (YES in S10), the engine ECU (100) implements fuel addition from the fuel addition valve (80) (S20). Then, when the exhaust temperature rises to a threshold temperature (?T) or above (YES in S40), the engine ECU (100) changes the fuel addition implementation temperature from the preset temperature (T1pset) to the temperature (T2) lower than the preset temperature (T1pset) (S50).
