Summary:A lightweight connecting rod made of a low-carbon martensite steel was used in Nissan's V6 twin-cam VQ engine. The rod was developed with the aim of achieving additional weight savings while continuing previous manufacturing advantages. The design of small and large ends was optimized using the finite element method (FEM), bolts were lightened by adopting a new technique of tightening them to the plastic region and the weight of the pistons was reduced. These improvements contributed to a weight reduction of 25% compared with the previous engine model.
