FEAD (Front End Accessory Drive) transmits an appropriate driving torque to each accessory component such as Generator, Power steering pump, Air conditioning compressor, and Water pump on automotive engines. The purpose of this study is to investigate a possibility of a fuel efficiency improvement by applying FEAD Mechanical Isolator. Most of FEAD systems tend to have higher belt tension than required to prevent unwanted system behavior in transient conditions. This excessive belt tension contributes to increased friction torque, and in turn leads to additional fuel consumption. Dynamic torque fluctuation of FEAD is another contributor to increase the friction torque. At near the resonance rpm, dynamic torque is fluctuated by an interaction of belt speed fluctuation and accessory component inertia. In this study, FEAD Mechanical Isolator is applied in an attempt to reduce the belt tension and torque fluctuation. Motoring test is performed to determine the effectiveness of FEAD Mechanical Isolator on friction torque. Finally, computer aided analysis is used to estimate the fuel consumption.
