Design Concept of Magnesium Accessory Drive Brackets 910553

Chrysler Jeep & Truck Engineering Division has developed a new accessory drive system for the 2.5L and 4.0L in-line engines. This system was designed to comply with program management assumptions which were set to meet customer needs and satisfy government requirements. The design objectives dictated a lightweight and cost efficient engine without compromising its quality or durability. These objectives were achieved by introducing magnesium as a replacement to aluminum in the engine accessory drive mounting brackets. The selection was based on strength-to-weight ratio, weight reduction, durability, corrosion performance, prototype requirements and cost efficiency.
