Bosch reaches stop/start milestone

Bosch has announced that it has produced its five millionth stop/start system in Hildesheim. The German Tier 1 says that since production began in 2007, more and more orders have come in for the fuel-saving technology. “Stop/start is a cost-effective way to reduce fuel consumption considerably,” said Dr Ulrich Kirschner, president of the Bosch starter motors and generators division. “We are expecting every second new car in Europe to be fitted with a stop/start system by 2013,” Kirschner added. At present, one new car in three features the technology and almost all European car makers are now integrating Bosch stop/start technology into a range of vehicles, including compact cars, premium sedans, and even powerful sports cars.

In the NEDC, stop/start reduces fuel consumption and CO2 emissions by up to 5%, but in the NEDC urban cycle, the saving can be as much as 8%, helping OEMs to meet stringent emissions legislation.

In order to further reduce consumption and CO2 emissions, Bosch engineers will in future extend engine shutdown-times that the stop/start system implements. This will apply initially to the time when the vehicle is rolling to a halt, and later even to periods when the driver is merely no longer accelerating. “Depending on the type of route, the enhanced start-stop systems can save an additional 10% of fuel,” Kirschner added.
