| Bosch and Mahle are establishing a 50:50 joint venture to manufacture and market exhaust gas turbochargers. The firm will allow Bosch to offer OEMs a single source for the key engine downsizing technologies.
The use of exhaust gas turbochargers is already common in diesels and is expected to become more prevalent in gasoline engines too. Turbos, combined with the advanced injection technologies that Bosch already produces, will be a key technology in fuel-saving engine downsizing concepts.
Mahle chairman Dr Heinz Junker said: “Mahle and Bosch complement each other as partners for turbo development. We have experience in high temperature-resistant turbocharger components and the design and application of turbocharged engines; Bosch has a leading position with gasoline direct injection and commonrail diesel technologies.”
Bosch Mahle Turbo Systems will start series production in 2010. The turbos will not be standard units. Mahle has been working on a mechatronic actuator for the wategate that will improve response. It also has an electrically actuated variable flow turbine for diesels and an electrically actuated exhaust gas recirculation valve in development.
