Gates improves fuel economy in trucks Vehicle accessories typically consume 30-50 percent of the energy produced by internal combustion engines. They consume more energy during highway driving, less energy during city driving, and much less energy during the engine idle cycle. Accessories are sized mostly for the engine idle cycle. Gates advances in belt technology are driving research and development of Two-Speed Accessory Belt Drive Systems. Gates new E3 Drive System optimizes engine accessories for significantly improved vehicle performance. Technological advancements • Allows accessories to operate at reduced speeds at off-idle conditions. • Reduces fuel consumption and C02 emissions up to 5 percent in the city and up to • Vehicle accessories operate more efficiently, and with greater reliability and durability. • Vehicle acceleration is improved because less torque is required to drive the accessories at lower speed. • Reduces engine at idle to further reduce fuel consumption and emissions. System components The E3 Drive System incorporates two main components (dual pulley clutch assembly) connected by a Micro-V® belt. Rochester Hills, Aachen, Germany Nara, Japan
