Modern clean diesel fuel delivery and engine management technology from Robert Bosch LLC are featured on Volkswagen of America’s 2009 Jetta TDI and SportWagen, the country’s first-launched 50-state compliant clean diesel vehicles. The cars are being displayed at the Los Angeles Auto Show. Today’s clean diesel is cleaner and more fuel efficient, without customers having to sacrifice fuel economy for engine performance.
The vehicle’s 2.0-liter turbocharged direct injection (TDI) engine uses the latest generation of Bosch clean diesel common rail system capable of up to 1800 bar (nearly 30,000 psi) and multiple (up to five) pre- and post-injections through piezo-electric injectors.
Additional vehicle content from Bosch includes the high-pressure pump, engine electronic control unit, diesel particulate filter, low-pressure exhaust gas recirculation pressure sensors, cam sensors, lambda sensors and the hot film air mass sensor, and glow timing electronic control unit.
