Abstract

PURPOSE:To cut off the vibration of an engine and to reduce the noise emitted from the surface of the engine by a method wherein metal members having vibration absorption properties are inserted between members of the engine that can propagate impulse vibrations due to piston slap generated by reciprocating movement of a piston. CONSTITUTION:In a diesel engine, when a clearance between a piston 6 and a cylinder liner 5 is large, the piston will be knocked to a side wall of the cylinder liner and then to the opposite side wall thereof, and therefore the piston slap is rusulted. Metal members 18-22 (Fe-Cr-Al alloy, etc.) having vibration absorption properties are inserted into at least three positions respectively, that is, a position between the cylinder liner 5 and the frame 1, a position between the frame 1 and a platform plate 2, and a position between upper and lower bearing metals 13, 14 of a crank journal 11 and a platform bearing portion 3 and bearing cap 4. Thereby the impulse vibration due to the piston slap is cut off on the way of propagation and also the noises emitted from the surface of the engine are reduced.
