Bosch’s Innovative Powertrain Technologies Improve Fuel Economy, Reduce Emissions

Bosch Offers Full Range of Powertrain Solutions Including Diesel Common Rail, Gasoline Direct Injection and Powertrain Electrification
FARMINGTON HILLS, Mich. –The demand for fuel efficient vehicles in the U.S. continues to grow as consumers become more aware of alternative, fuel-friendly technologies. This, coupled with the new energy policy focused on reducing dependence on oil, creates a landscape ready for innovative powertrain technologies. Bosch, a leading supplier of powertrain systems, is working with automakers to meet these growing demands.

“We are firmly committed to developing innovative and quality technologies that improve fuel economy and reduce emissions,” said Peter Marks, chairman, president and CEO, Robert Bosch LLC. “We are working with automakers on a wide range of products that help achieve market demands.”

Bosch is uniquely positioned to provide a full range of powertrain solutions. Today, the company offers advanced systems and technologies for clean diesel, gasoline direct injection, hybrid and transmission control. According to Marks, Bosch has the flexibility and experience to work with automakers to develop a powertrain that meets the specific needs and characteristics of a vehicle, while improving its fuel efficiency independent of what type of fuel the vehicle uses.

Additionally, Bosch remains focused on advancing future powertrain technologies, including parallel electric hybrids and full electric vehicles. Joe Slenzak, manager, hybrid-electric vehicle business development, Bosch North America said, “we see powertrain electrification as an evolution from current hybrids, to more advanced hybrid systems, and finally, to pure electric vehicles. “

In 2008, Bosch announced the creation of SB LiMotive, a 50-50 joint venture with Samsung to produce lithium ion batteries, advancing the company activities in the electrification of powertrain.

Following is a closer look at Bosch technologies available today:

Diesel Common Rail
Over the last two decades, Bosch diesel common rail systems have dramatically improved performance while providing one of the “greenest” powertrain options available today.

Bosch’s emission-reducing diesel engine technology includes high-pressure common rail and exhaust aftertreatment systems for improved performance and superior fuel economy, also for long distance driving. Clean diesel technology combines clean diesel fuel, advanced engines and effective exhaust control technology into a more efficient, environmentally friendly and fun vehicle to drive.

In comparison to gasoline port-fuel injection, the latest generation common rail system from Bosch, powered by piezo-inline technology, increases fuel economy by more than 30 percent, reduces carbon dioxide (CO2) emissions by nearly 25 percent and increases torque by 50 percent.

“Bosch has been developing for more than three decades various systems to make diesel engines clean and extremely fuel efficient,” said Bernd Boisten, regional president, Diesel Systems North America, Robert Bosch LLC. “We continue our efforts and will develop and manufacture diesel systems to meet the growing U.S. market for clean diesel technology.”

Recently, Bosch was recognized by the 2009 Automotive News Premier Automotive Suppliers Contributions to Excellence (PACE™) Awards program with an honorable mention in the product-Europe category for the Denoxtronic which in combination with the selective catalytic reduction (SCR) catalyst, converts the exhaust gas nitrogen oxides to steam and nitrogen. This enables the modern clean diesel vehicles to be compliant in all 50 U.S. states.

Gasoline Direct Injection (GDI)
Bosch’s innovative second generation gasoline direct injection system, DI-Motronic, allows for increased performance without sacrificing fuel economy. The system includes the engine control unit, high-pressure pump and magnet solenoid or piezo fuel injector.

GDI, when combined with turbocharging, allows for the production of smaller displacement engines that achieve the same output while consuming less fuel and producing fewer emissions. Furthermore, the technology helps reduce CO2 emissions by up to 15 percent through an improved gas and air mixture process.

“Our innovative GDI system is a unique, fuel-saving technology that is widely adopted by automakers today,” said Sujit Jain, regional president, Gasoline Systems North America, Robert Bosch LLC. “Together, with our customers, we’re able to bring this technology and better fuel economy to life for consumers.

Bosch will be manufacturing the core components that make hybrid systems functional, including electric machines, power electronics (inverters, DC/DC converters) and on board chargers. In addition, Bosch can supply complete hybrid solutions - hybrid control software, ECUs and system engineering.

“Bosch has been focused on developing and implementing advanced hybrid technologies for many years,” Slenzak said. “Bosch’s first production hybrid system will be available in the U.S. in 2010 through collaboration with a European automaker.”

Bosch’s hybrid technology has the ability to improve fuel economy up to 30 percent while reducing emissions by 25 percent.
