  • Arrangement for and a method of maintaining the alignment of an internal combustion engine, and a method of aligning an internal combustion engine and maintaining its alignment
    Patent number: 9777626
    Abstract: An arrangement and method for maintaining an alignment of an internal combustion engine by utilizing an arrangement includes a number of fluid springs by means of which the engine is mounted on a foundation thereof, control valves arranged in communication with each fluid spring, at least three position sensors in communication with the engine, and an electronic control unit. The electric control unit is provided with preset engine position values. The method includes collecting engine position information to the electric control unit, comparing the position information to preset position values, determining, if the position information differs from the preset position values, such control valves that need to be operated, calculating the corrective measures, and giving corrective instructions to the control valves.
