Reduced consumption and CO2 emissions New “Efficiency Line” generators from Bosch Ideal addition to start-stop systems
Bosch recently started production of a new, enhanced-efficiency generator series. An improved electrical configuration and optimized materials have enabled the manufacturer’s engineers to increase the efficiency of all variants to over 70 percent (according to VDA). The Efficiency Line (EL) generators consequently need less mechanical power to generate the energy for the vehicle’s electrical consumers. This reduces fuel requirements – and t...
