    Abstract: A cylinder head cover for a hydrogen-fueled internal combustion engine includes a head cover body and an outlet passage. The head cover body defines a main passage for blow-by gas that has leaked from a combustion chamber to a crankcase. The outlet passage is connected to a downstream end of the main passage and conducts the blow-by gas to an intake passage. The main passage includes a restriction in a middle of the main passage. The cylinder head cover further includes an auxiliary passage. The auxiliary passage is connected to a section of the main passage that is on the upstream side of the restriction. The auxiliary passage conducts the blow-by gas to the outlet passage or the intake passage.

    Abstract: Various embodiments include a method for monitoring the ventilation of a crankcase of an internal combustion engine with combustion chambers and a nitrogen oxide sensor arranged in an exhaust system, the sensor configured to detect an amount of nitrogen oxide in exhaust gas of the internal combustion engine. An example method includes: determining a predefined operating mode of the internal combustion engine defined by substantially no combustion of an air/fuel mixture taking place inside the combustion chambers; determining an amount of nitrogen oxide in the exhaust gas during the predefined operating mode of the internal combustion engine using the exhaust gas sensor; and identifying functional ventilation of the crankcase if the detected nitrogen oxide level exceeds a predefined nitrogen oxide threshold or identifying a malfunction if the detected nitrogen oxide level is below the predefined nitrogen oxide threshold.

    Abstract: An oil collection device for use with an engine having an oil filter mounting structure and an oil filter mounted thereto is provided. The oil collection device comprises a tray including a concavity that is open from above. The oil collection device further comprises a first connector formed on the tray, in which the first connector includes an attachment structure configured to removably attach to a portion of the engine below the oil filter. The oil collection device further comprises a second connector formed on the tray, in which the second connector has a drain hole formed therein, the drain hole extending through the tray and opening to the concavity, the second connector being configured to attach to a drain hose.

    Abstract: A functional component of a fluid filter is provided with at least one component connection element of a mechanical connection device, wherein the at least one component connection element can be connected releasably to at least one corresponding housing connection element of the mechanical connection device by a rotation/push-in movement about a virtual axis. The at least one corresponding housing connection element is provided at a filter housing of the fluid filter. The at least one component connection element has at least one securing contour that interacts with at least one joining element to secure the mechanical connection device and prevent an accidental release of the mechanical connection device, wherein the at least one joining element is connected to the filter housing after the functional component has been mounted at the filter housing.
