Bosch recently started production of a new, enhanced-efficiency generator series. An improved electrical configuration and optimized materials have enabled the manufacturer\u2019s 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\u2019s electrical consumers. This reduces fuel requirements \u2013 and therefore CO2 emissions, too. The new Bosch generators were first introduced at MINI and in the Ford Transit.<\/p>\n
<\/p>\n
The demand for electricity in cars has been rising constantly in recent years due to the increasing number of comfort and safety systems in vehicles. As a result, more and more attention is being devoted to the efficiency of all consumption components and the generator. With ultra-efficient diodes, which are available as an option, the efficiency of the new generators can even be improved by as much as 77 percent. \u201cIn real-time driving, Bosch EL generators can reduce fuel consumption by up to 2 percent,\u201d says Dr. Ulrich Kirschner, president of the Bosch Starter Motors and Generators division.<\/p>\n
Already in engine idle \u2013 which is equal to a generator speed of approximately 1,800 revolutions per minute \u2013 the EL generators produce about 10 percent more power. They are therefore an ideal complement to start-stop systems, as they ensure the fastest possible battery charging. As a consequence, the start-stop function can be used more frequently. \u201cBoth technologies are elements of Bosch\u2019s Efficiency Plus Solutions. Together, they enable consumption savings of up to 10 percent,\u201d Kirschner says.<\/p>\n
An additional analogue or digital communications interface such as LIN (Local Interconnected Network) creates the conditions for intelligent generator regulation. This in turn allows most of the electricity to be generated in coasting mode, which in turn means a fuel saving of up to 2 percent. The EL series is available in various sizes and covers a performance range of 130 to 210 amperes (at 6,000 rpm). The generators are therefore ideal for the reliable energy supply of the most diverse vehicle electrical systems \u2013 from passenger cars to vans. Designed for especially quiet operation, they can also be used at high ambient temperatures of up to 125 \u00b0C.<\/p>\n","protected":false},"excerpt":{"rendered":"
