Abstract:
The primary objective of this study was to provide an efficient system solution for the removal of fuel from an Active Drain Liquid Trap (ADLT), used in automotive vent systems; using a Jet Pump. The Voice of Customer was collected and analyzed. The two major focus areas identified were - improvement in robustness of Jet Pump performance and maximization of induced flow. Robust design of such a Jet Pump was carried out using Taguchi's Orthogonal Crossed Array based parameter design, through computer simulation. Two Jet Pumps were designed for Gasoline based vehicles; one with the conventional approach and the other with the robust design approach. Both were put on a field trial, integral with the vent system. The robust design showed a tremendous improvement in performance over the conventional design, due to the elimination of cavitation and insensitivity to noises.
