SINGLE-SINTERED CON RDDE FOR AUTOMOBILES

Connecting rods are becoming on increasingly high volume market for the powder metallurgy industry. At present the Components are powder forged. Many efforts have been made recently to develop a single-sintered Connecting rod. Within the scope of the European Community's COST 503 program,two cooperative projects were undertaken with Swedish,British and German partners,with the aim of developing single-sintered and weight-optimized connecting rods for relialble operation in 1.8 to 2.0 litre automotive engies. The fatigue strength behaviour obtained with single-sintered connecting rods is equivalent to that of the present used optimized cast connecting rods. The performed engine test runs proved that reliable operation is assured.
