Bosch Efficiency Line: New generators with increased efficiency of an ideal solution for the "start-stop" efficiency up to 77% higher power at low engine speeds fuel economy up to 2% in real driving conditions Bosch product line replenished new generators with increased efficiency. Models Series Efficiency Line (EL) are designed for vehicles with a variety of safety features and comfort, which require more electricity. Through further improve the electrical circuit and the use of additional diodes, developers were able to bring Bosch generator efficiency up to 77%. In other words, new models need less energy to mechanical making the same electrical power. "This would in real driving conditions to reduce fuel consumption and CO2 emissions by as much as 2%", – said Head of starters and alternators Stephan Bosch Azenkershbaumer. The company plans to start producing a new series of generators in 2010, official statistics on fuel consumption were obtained in laboratory tests, the parameters which define the conditions of the New European Driving Cycle (NEDC).
Electrical devices that operate during the test cycle, consumes about 350 watts from the mains of the vehicle. In the urban component of the NEDC Generators The EL reduce consumption by 0.5%. In more realistic conditions, when the average power consumption is 1000 watts, saving energy increases four-fold, to 2%. The largest number of fuel saving in the most efficient power generation during idling, ie when inertial motion or braking. This requires an intelligent generator control analog or digital interface (for example, a digital interface may serve as a LAN LIN).
In this case the generators can be installed in any point of the engine compartment: models of the new series can withstand temperatures up to 125 C. The ideal solution for the "start-stop" EL Series generators are available in three sizes with a current strength of 130 to 210 A. From the previous models they are different and higher power output at low engine speeds, making ideal for systems such as "start-stop." New Generators ensure that the battery will be effectively charged even at idle, ensuring reliable operation of the function "start-stop." As a result, this system can be used more often, which allows to further reduce fuel consumption. The combination of generator and Bosch EL system "start-stop" reduces fuel consumption (and hence emissions of CO2) emissions in urban driving mode as much as 10%.
