Development and Application of ADI Crankshaft for Turbocharged Diesel Engine

The technology and production possibility of using ADI for making turbocharged diesel engine crankshaft, as well as its economic benefit and market was analyzed. The development process and result of the ADI crankshaft for a turbocharged 6 cylinders diesel engine was described. The properties of the trial ADI crankshaft was as following: tensile strength of 900~1 070 MPa,elongation of 7%~9%;hardness of 31~34HRC,fatigue bending moment M-1=3 100 N-M,safety factor 1.8. Suggestion was also proposed on the industrialization of ADI crankshafts.
