Embodiment Construction

[0038] figure 1 A front view of piston engine 10 is shown schematically. The engine comprises at least one cylinder 15 in which a piston 20 is arranged to reciprocate during operation of the engine in a manner known per se. The piston 20 is connected to the crankshaft 25 of the engine via a connecting rod 30 . When the engine is running, the reciprocating motion of one or more (when the engine is a multi-cylinder engine) pistons causes vibrations of the engine, which vibrations are schematically indicated by the arrow V. In order to damp said vibrations, the engine is provided with a device for damping vibrations 100 attached to the engine. exist figure 1 In the embodiment shown, the device 100 for damping vibrations is attached to the oil pan 35 of the engine, which is advantageously positioned because the space therein can then be used efficiently and the installation of the device in the engine requires only Minimal changes in the engine. It is conceivable that the eng...

Abstract

The invention relates to an arrangement for attenuating the vibration of a piston engine comprising a tuned mass damper (110) having at least one mass element (120) and at least one spring element (130). The mass element is rotationally supported so that the rotational axis is set off from the axis of the center of gravity of the mass element (120) and the at least one spring element (130) is arranged to the mass element (120), driving the mass element to a rotational rest position of the tuned mass damper (110).

Description

technical field [0001] The invention relates to a method for damping vibrations of a piston engine according to the preamble of claim 1 . The invention also relates to a piston engine according to the preamble of claim 7, having at least one reciprocating piston arranged in a cylinder, which piston is coupled to the crankshaft of the engine. Furthermore, the invention relates to a method of damping vibrations of a piston engine according to the preamble of claim 10, in which method the vibrations are damped during operation of the engine by means of a tuned mass damper, which There is at least one vibrating mass element and at least one spring element arranged in association with the engine, and in the method excitation from the engine provides vibration of the mass element of the damper to damp vibrations of the piston engine. Background technique [0002] The vibrations of piston engines are known per se, and to reduce them there are many different solutions. In an engin...
