Abstract
A crankshaft of a V-type 6-cylinder internal combustion engine which ensures a decrease of the engine vibration and surface pressure affecting each crank journal by achieving effectively dynamic balance of a whole crank shaft and dynamic balance couple between inner main bearings with an optimum size of balance weight.
The crankshaft of a V-type 6-cylinder internal combustion engine of this invention including first to sixth crank pins connected with connecting rods, having first to fourth crank journals between the first to sixth crank pins, and first to ninth crank arms between first to sixth crank pins and the first to fourth crank journals, comprises:
a first balance weight provided to the first crank arm, the center of gravity of the first balance weight being mal-distributed to the lower part with respect to the center axis of the crankshaft; a second balance weight provided to the second crank arm, the center of gravity of the second balance weight being mal-distributed to the lower part, and deviated from the first balance weight in a counterclockwise direction; third and fourth balance weights provided respectively to the fourth crank arm and sixth crank arm and having centers of gravity deviated upward and downward and orthogonally in a clockwise direction with respect to the center of gravity of the first balance weight a fifth balance weight provided to the eighth crank arm, the center of gravity of the fifth balance weight being in vertical symmetry with the second balance weight; and a sixth balance weight provided to the ninth crank arm, the center of gravity of the sixth balance weight being mal-distributed to be in vertical symmetry with the first balance weight.
