          Renault engine prototype designed for additive manufacturing

          Company & Department:
          Renault Trucks, Lyon Powertrain Engineering Department

          Project & Product:
          using metal additive manufacturing as a future engine manufacturing process, for engine prototype DTI 5 4-cylinder Euro-6 Step C Engine

          Approach:
          engine prototype is exclusively designed for additive manufacturing (DfAM), with the aim to reduce the weight and size

          Benefits:
          Weight reduce by 25% or 120Kg
          Component number reduced by 25% or 200 fewer parts

          Preliminary Validation:
          Engine rocker arms and camshaft bearing caps were manufactured by metal additive manufacturing
          Above parts were successfully bench-tested for 600hours inside a Euro-6 engine

          Suggestions:
          Priliminary test proved the durability of engine components made using metal additive manufacturing
          Design for additive manufacturing allows engineers to optimize the size of parts, reduce the number of component number in an engine and therefore the assembly operations (resulting in lighter and more functional and optimal performance for the engines of tomorrow)
