Bosch celebrates production milestones

In our last issue, we covered the Bosch international press briefing, where the company unveiled its strategy for development over the next few years. In the same month, Bosch also celebrated two production milestones: the manufacture of 25 million HDEV5-series fuel injectors and five million HDP-line high pressure pumps within its ‘Gasoline Systems’ business division. Both products went into largescale series production in 2006, with the HDP line first featured in GM’s Ecotec engine, while the HDEV5 series was initially applied in PSA/BMW’s Prince engine. The company produces high-pressure pumps and fuel injectors at its lead plants in Nuremberg and Bamberg (both in Germany) as well as in Turkey and China. The high-pressure pumps and fuel injectors are part of its Motronic Electric Engine Management system, which - combined with turbocharging - reduces fuel consumption and CO2 emissions of internal-combustion engines with petrol direct injection, by 15%. With increasing focus from automakers on engine downsizing, the company believes the international market for petrol direct injection systems will only rise. “Bosch expects the share of gasoline direct injection to triple by 2015, to 18% of global car production,” says Dr. Rolf Bulander, President of the Gasoline Systems division. The HDEV5 high-pressure injection valve works by virtue of up to seven individually positioned injection holes that enable the spray pattern to be adapted to each engine. The highpressure injection valve and pump are designed for system pressures of up to 200 bar, yet remain compact and light, weighing in at just 780 grams. The use of stainless steel means that the current components of the petrol direct injection system are designed for worldwide use and thus for great fuelquality tolerance.
