An engine brake for an engine, having a rocker shaft carrying rocker arms along a rocker shaft, has an eccentric mounted to the rocker shaft and couples one of the rocker arms to the rocker shaft to pivot eccentrically about the rocker shaft as the eccentric pivots. The eccentric may take a braked condition or an unbraked condition. An actuator is capable of pivoting the eccentric about the rocker shaft to move the eccentric from the unbraked condition to the braked condition. An anti-clatter assembly is movable from an active state associated with the unbraked position of the eccentric to an inactive state associated with the braked condition of the eccentric. The anti-clatter assembly provides to the eccentric a restraining force in the active state and a yielding force in the inactive state. The restraining force is greater than the yielding force. The restraining force is sufficient to impede the eccentric from pivoting about the rocker shaft in the unbraked condition. The yielding force is insufficient to impede pivoting of the eccentric in the braked condition.

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.

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.

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.
