High Strength Light-Weight Valve Spring for Automotive Engine to Enhance Fuel Efficiency 2012-01-0528

High strength oil-tempered wire was developed to apply to light-weight valve spring for automotive engine. By adding Mo, V, B and Ni, tensile strength increased by 20% compared to the conventional oil-tempered wire. Higher tensile strength of wire enabled a constant of valve spring to lower by reducing the size of spring. As a result, reduction of spring constant lowers the load of spring, thereby enhancing fuel efficiency.
