Optimization of Intake Manifold Design using DFSS (Design for Six Sigma) 2007-01-3534

DFSS (Design for Six Sigma) is a very useful method to optimize product design in various fields of the industry. This paper presents the implementation of the DFSS method to optimize an engine intake manifold with PDA system. The focus of optimization is to maximize the swirl strength and mass flow rate in the cylinder chamber. There are so many factors that affect the swirl strength and mass flow rate in intake manifold system, but only six main control factors such as plenum shape, primary and secondary length, port diameter, primary pipe section shape, etc. are adopted. The L18 orthogonal table is used for calculating CFD simulation to evaluate the swirl number and mass flow rate in the cylinder chamber.
