Abstract: An internal combustion engine has a multi-joint crank drive which includes a plurality of coupling members rotatably mounted on a crankshaft and a plurality of articulated connecting rods rotatably mounted on an eccentric shaft, wherein each of the coupling members is pivotably connected to a piston connecting rod of a piston of the internal combustion engine and to one of the articulated connecting rods. In order that the second-order mass forces can be better compensated without a considerable increase in the friction losses, the required packaging space, the weight of the multi-joint crank drive, or the bearing forces in the bearings of the crankshaft, the articulated connecting rods are provided with additional masses and have a center of mass that lies outside the longitudinal center planes of the articulated connecting rods.

The vibration alleviation unit is disposed at least one of upon the crankshaft and upon a part that operates in unison with the crankshaft. The three cylinder is supported by engine mounts that are positioned upon at least both ends of the engine in the direction of the crankshaft axis. Given that KV and KH represent spring constants of one of the engine mounts in the pitch and yaw directions of the crankshaft, MV and MH represent components of a primary couple that occurs in the three cylinder engine in the pitch and yaw directions, and MV0 represents the sum of MV and MH, then spring constants of the engine mounts are set such that KV>KH and the vibration alleviation unit is set so as to satisfy the condition 0

Abstract: An internal combustion engine includes a crankcase, a cylinder, a piston, a crankshaft, and a piston connecting rod. A counterweight connects to the crankshaft through a counterweight connecting rod. The counterweight pivotally connects to the crankcase. The engine is constructed such that the crankshaft drives the counterweight less than 180 degrees out of phase with the motion of the piston. A center of gravity of the crankshaft is offset from the crankshaft's axis and moves out of phase with the piston by less than 180 degrees. The offset counterweight and crankshaft balance out inertial forces in the engine to reduce engine vibrations and improve engine performance.

Abstract: In an engine operated machine system including a hollow support rod connected at one end to an engine through a vibration insulator, an auxiliary weight is mounted at the other end of a crankshaft for generating a centrifugal force in the same direction as an inertia force of a piston, when the piston reaches top and bottom dead centers. Thus, it is possible to bring a center of gravity of the engine closer to the position of the vibration insulator, thereby suppressing the application of the vibration from the engine to the support rod to the utmost.

Abstract: An improved counterweight for a crankshaft having a main body which is adapted to rotate about a predetermined axis. The main body includes a major lobe on one side of the axis and a diametrically opposed minor lobe. Two recessed surfaces extend on opposite sides of a diametric line bisecting the major and minor lobes so that the recessed surface forms a portion of the outer periphery of the crankshaft. A pair of inserts is provided and each insert has a surface complementary to one of the recessed surfaces on the main body. Each insert is inserted into the main body to form a generally cylindrical counterweight.
