摘要： A valve motion measurement assembly is provided for a cylinder valve of an internal combustion engine provided with a valve stem and with a valve head. The valve motion measurement assembly includes a valve position sensor, a supporting bracket provided with at least one sensor seat for the valve position sensor, and a sensor target element configured to be coupled to the valve stem at a distance from the valve head to follow the motion of the cylinder valve. The valve position sensor interacts with the sensor target element for determining the position of the cylinder valve.

摘要： A roller tappet for a fuel unit pump of an internal combustion engine is provided with a roller tappet bore for inserting the roller tappet within the internal combustion engine. The roller tappet includes a roller tappet body having a body longitudinal axis for connecting the roller tappet to a reciprocating element of the fuel unit pump. A cam roller contacts a cam lobe of a rotatable shaft of the internal combustion engine. The cam roller is rotatably mounted to the roller tappet body around a cam roller rotation axis. The external surface of the roller tappet body is configured to allow tilting of the roller tappet within the roller tappet bore for aligning the roller tappet with respect to the cam lobe of the rotatable shaft.
