A starter assembly includes a housing defining an interior, a rotatable pinion gear wherein the rotatable pinion gear extends exteriorly of the housing and operably coupling to a combustion engine, a torque sensor providing a torque output indicative of a torque experienced by the pinion gear, and a controller module configured operate a starting sequence for the starter assembly.

A barring-tool system improving safety, speed, effectiveness, and number of personnel required for maintenance, repair, and inspection of large engines, generators, and turbines, providing controlled bidirectional rotation and locking of crankshafts during maintenance, and a method for maintenance of large engines, generators, and turbines using the barring-tool system.

A method actively dampens a start-up resonance of a torsional damper when starting an internal combustion engine. The torsional damper (4) is fixed between an internal combustion engine (1) and a secondary side (5) of a torsional elasticity, and the internal combustion engine (1) is started using a starter generator (3) arranged on a side of the internal combustion engine (1) counter to the torsional elasticity. A counter excitation is applied to a torque generated by the starter generator (3) when the internal combustion engine (1) is started, which counter excitation is modulated on the basis of a parameter of the internal combustion engine (1) which changes when the internal combustion engine (1) is being started.

A fuel filter element, which may be selectively arranged in a filter housing and may separate in the filter housing an untreated space communicating with an inlet and a return line of the housing from a treated space communicating with an outlet of the housing, may include at least one end disk, and at least one closure element, which in an operationally ready state of the fuel filter may close off the return line. The closure element may protrude eccentrically axially away from the at least one end disk. The closure element may have a seal on a surrounding surface and that, in the operationally ready state, may be in contact with a surface of the return line. In the operationally ready state, a portion of the closure element may be located in a filter chamber of the filter housing and another portion of the closure element may be located in the return line.
