MUMBAI, India, Aug. 29 -- Intellectual Property India has published a patent application (202441014087 A) filed by Bosch Limited; and Robert Bosch Gmbh, Bangalore, Karnataka, on Feb. 27, 2024, for 'a controller and method to monitor a three-way catalyst in exhaust conduit of a vehicle.'
Inventor(s) include Prashanth Devendran Sumathi; and Nidith Rai.
The application for the patent was published on Aug. 29, under issue no. 35/2025.
According to the abstract released by the Intellectual Property India: "The controller 110 configured to measure the first temperature, using the first temperature sensor 116, at mid-point of the TWC 106, measure the second temperature, using the second temperature sensor 118, post the TWC 106 and calculate a relational value between the first temperature and the second temperature in a drive cycle. The first temperature sensor 116 and the second temperature sensor 118 measure/determine the respective temperature continuously in real-time at every time instant and do not correspond to a single value, but to a series of values. The controller 110, characterized in that, configured to process the calculated relational values using the computational module 120. The controller 110 then determines ageing (or aging) of the TWC 106 based on comparison of an output of the computational module 120 with the respective threshold value. The threshold value is stored separately for the difference and ratio based relational values."
