Abstract
In this paper, Front Engine Accessory Drive (FEAD) system of automotive engine is modeled with ADAMS software. The model is validated using engine test data. It is then used to investigate the effect of design parameters on the system performance such as belt vibration and loads on the idlers. Three alternative layouts were developed in order to improve the performance of original EEAD system. The validated model was used to study the effect of changes made to the layouts on the reduction of vibration and loads. Several system outputs indicated that for the modified layouts, large reductions in vibration and loads were achieved. It was concluded that one of proposed layouts was more appropriate and could be a useful substitution to the original layout. The developed model also proved useful for the design of engine FEAD systems and could be used for further developments.

Abstract
the primary objective of this work is to introduce a gear ratio selection strategy for a CVT equipped vehicle and show
its effectiveness on the fuel consumption reduction. AFuzzy control algorithm is designed for this purpose. Anonlinear
model is developed for simulating the longitudinal vehicle dynamics with accelerator pedal applied by the driver as an
input. In order that pedal input values can be used for evaluation of control strategy, a pedal cycle concept was
introduced. With the help of these cycles different driving conditions were simulated and the fuel consumption results
were obtained using Advisor software. Results showed that the control system was successful in reducing the fuel
consumption, especially in low acceleration driving cycles
