MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202647126078 A) filed by Schaeffler Technologies AG & Co. Kg on October 22, 2026, for Method For Monitoring The Ventilation Of A Crankcase Of A Hydrogen Internal Combustion Engine, And Hydrogen Internal Combustion Engine.
Inventors include Fink, Fabian; Rodatz, Paul; and Haft, Gerhard.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The invention relates to a method for monitoring the ventilation of a crankcase (120) of a hydrogen internal combustion engine (100) and to a hydrogen internal combustion engine (100), which has combustion chambers (110) and a gas sensor (140) that is provided in the exhaust tract (130) of the hydrogen internal combustion engine (100) and is designed to generate a gas signal that is representative of the hydrogen content or oxygen content in the exhaust gas of the hydrogen internal combustion engine (100). The method according to the invention has the steps of: determining a specified operating mode of the hydrogen internal combustion engine (100) during which substantially no combustion processes of an air-hydrogen mixture take place within the combustion chambers (110); receiving a gas signal from the gas sensor (140) in the specified operating mode of the hydrogen internal combustion engine (100); determining the hydrogen content in the exhaust gas of the hydrogen internal combustion engine (100) at least partly on the basis of the received gas signal; and determining a functional ventilation of the crankcase (120) if the determined hydrogen content in the exhaust gas of the hydrogen internal combustion engine (100) exceeds a specified hydrogen content threshold value.
