Application of Life Cycle Design to Aluminum Intake Manifolds

Life cycle design (LCD) is a framework for designing product systems which are both economically and ecologically sustainable. Key elements of this framework are systems analysis, multicriteria analysis and multistakeholder participation. This paper illustrates the application of life cycle design for a comparative evaluation of a prototype sand-cast 2.0 l aluminum manifold for the 1995 Ford Contour and a 2.0 l equivalent of the 1.9 l multi-tube brazed aluminum manifold for the 1995 Ford Escort.
