  • Publication number: 20230184183
    Abstract: A method for checking the association of structure-borne noise sensors of an internal combustion engine having a plurality of cylinders, which internal combustion engine can be operated in diesel operation or with individualized gas injection and in the case of which internal combustion engine a structure-borne noise sensor is arranged in the region of each cylinder, wherein the output signals of the structure-borne noise sensors reflect a knock index and are captured by a computing unit, wherein the internal combustion engine is operated in order to perform the method. The output signals of all structure-borne noise sensors are determined during at least one working cycle, which is formed by two revolutions of a crankshaft, in the respective positions of the crankshaft. The output signal of a cylinder is compared with the average value or the median value of the output signals of other cylinders.

  • Patent number: 9248394
    Abstract: An air scoop-cyclone filter assembly having an air scoop for guiding untreated air, which including an inlet opening, a deflection area for deflecting untreated air and an outlet opening, and having a cyclone filter for cleaning untreated air, which is connected downstream of the air scoop in the flow direction and is connected in an airtight manner to the air scoop A perforated plate is arranged in the cyclone filter as a filter inlet opening. The perforated plate has a first passage area having a high number of holes, a second passage area having a low number of holes at the geodetically deepest point, and a baffle plate. The baffle plate distributes the untreated air flow through the first and second passage area and, with the outer wall of the air scoop, forms a collecting chamber that stabilizes the flow.
