Control Systems and Methods for Reducing Vibration in Internal Combustion Engines

摘要

Systems and methods are for controlling internal combustion engines having a plurality of piston-cylinders that cause rotation of a crankshaft. A crankshaft sensor is configured to sense rotational speed of the crankshaft. A controller is configured to calculate an acceleration for each piston-cylinder based upon the rotational speed of the crankshaft and then balance the accelerations of the respective piston-cylinders by modifying a combustion input to one or more of the piston-cylinders in order to reduce engine vibration.

1. A system comprising an internal combustion engine having a plurality of piston-cylinders that cause rotation of a crankshaft; a crankshaft sensor configured to sense rotational speed of the crankshaft; and a controller having a processor and a memory, wherein the controller is configured to calculate an acceleration of each piston-cylinder based upon the rotational speed of the crankshaft and then balance the accelerations of the respective piston-cylinders by modifying a combustion input to one or more of the piston-cylinders.
