Benefits of using TI6AL4V alloy for connecting rod and crankshaft of a four-stroke ICE

Abstract

The article presents the process of designing a connecting rod and crankshaft made of titanium alloy Ti6Al4V in accordance with the assumed dimensions. The Engine unit will power a vehicle taking part in the Shell Eco-Marathon competition. The elements were subjected to FEM simulation for static and fatigue strength to check their trouble-free operation. The research has had positive effects, making further modification of the designed parts unnecessary. The energy needed to set in motion elements made of steel and Ti6Al4V alloy was compared, which results in a difference in fuel consumption.
