| Abstract: | Material and process of engine connecting rod are discussed. The material of the connecting rod has developed from quality alloy structural steel with medium carbon level to micro alloying steel with medium carbon or high carbon level. The corresponding heat treatment process includes hardening and tempering, quenching by heat from the forging itself and controlled cooling after forging. The parting process of connecting rod big end bore has developed from cutting to fracture splitting. |

| Keywords: | connecting rod micro alloying steel fracture splitting process |
