    Abstract: An engine valve actuation system includes a hydro-mechanical valve actuation module having a first hydro-mechanical linkage and a second hydro-mechanical linkage, each within a different housing block of a housing. Each of the first hydro-mechanical linkage and the second hydro-mechanical linkage includes a cam-follower piston in contact with a cam of a camshaft, and a valve-actuation piston hydraulically co-acting with the respective cam-follower piston. The hydro-mechanical valve actuation module may include hydro-mechanical linkages for an intake valve, for an exhaust valve, and for engine braking.

    Abstract: A system includes an ECM configured to control at least one subsystem of a machine, a plurality of sensors communicatively coupled to the ECM, the plurality of sensors configured to sense at least one identification device coupled to a fluid filter associated with the subsystem of the machine. A memory stories instructions that, when executed by the ECM, cause the ECM to cause a sensor of the plurality of sensors to sense the at least one identification device, receive a signal from the sensor based on the sensor sensing the at least one identification device, identify a coupling of the fluid filter to the machine based on the signal; and identify at least one physical characteristic of the fluid filter based on a code defined by electromagnetic energy generated by the at least one identification device. The code includes at least one component defining the at least one physical characteristic.
