Abstract: A method of manufacturing a bearing pin with an external lubrication channel and the bearing pin formed thereby are disclosed. The method includes fixing a rotational orientation of the bearing pin along a pin axis, cutting an outer surface of the bearing pin in a first straight line across a first convex portion thereof to create a first open external groove of the lubrication channel; and cutting an outer surface of the bearing pin in a second straight line across a second convex portion thereof to create a second open external groove of the lubrication channel. The grooves have a concave sectional profile and circumferential open ends disposed intermediate and not intersecting the ends of the bearing pin.

Abstract: An engine braking system includes a camshaft, a follower, an exhaust armature, a lever, and a hydraulically actuated piston. The camshaft includes at least one cam. The cam has a lobe and a brake bump. The follower engages the cam. The exhaust armature is coupled to the follower. The lever is coupled to the exhaust armature. The hydraulically actuated piston moves the lever. Hydraulic actuation of the piston causes a change in lash distance between the cam and the follower. In an engine brake mode, the follower contacts the cam throughout rotation of the cam.

Abstract: The invention relates to an aerosol separator for separating aerosols in a blow-by gas, which comprises at least one feed opening for feeding a blow-by gas provided with aerosols, an outlet opening for discharging a blow-by gas cleaned of aerosols, at least one outflow opening for releasing aerosols removed from the blow-by gas, and which is arranged between a flow path of the at least one feed opening and the outlet opening, and a plurality of projections for configuring the flow path running from the at least one feed opening to the outflow opening in a meandering manner, in order to decelerate the blow-by gas which enters the feed opening and which is provided with aerosols, in terms of its flow rate. The separator is characterized in that the projections in their end region, around which blow-by gas flows, have a portion with increasing projection width.
