Design for Environment (DfE) of Ultralight Aluminum Camshaft Development
In order to solve problems modular type camshafts have, that is, reducing weight, increasing oil filling time and designing multi-valve system, research was initiated about feasibility for DfE (Desing for Environmrnt) about ultralight camshaft . Through LCA (Life Cycle Assessment) and properties and process evaluation, an attempt has been made to develop cost-effectvie process for ultiralight aluminum camshaft without the problems modular type camshaft have. The results clearly show 50% weight reduction achieved and better environmental impact of the ultralight aluminum camshaft compared with that of modular camshafts.
