Experimental Analysis of Bending Stresses on the Crankshaft in a V-Type Six-Cylinder Diesel Engine 2005-01-2488
Engine vibration is a great disadvantage of a V-type six-cylinder engine because ignition does not occur at regular intervals. The engine achieves ignition at regular intervals by having a crank pin offset crankshaft. The shape of the crank pin offset crankshaft is so complex that the location of the crank pin on which bending stress concentrates cannot be obtained easily. This paper reports on the mechanism that generates bending stresses on the crank pin, and discusses the location at which the maximum bending stress is generated with crank pin offset crankshaft.
