Bosch Supplies Key Powertrain Technologies for Ward’s 10 Best Engines for 2010


FARMINGTON HILLS, Mich. – Bosch supplies powertrain technologies to multiple vehicles named to Ward’s 10 Best Engines of 2010 list, including four applications featuring its diesel common rail and gasoline direct injection systems. The Ward’s 10 Best Engines of 2010 Awards were presented in Detroit on Jan. 13, during the North American International Auto Show (NAIAS).

Award-winning engines featuring Bosch technologies include:

  • Audi AG’s 2.0L TFSI turbocharged direct-injection 4-cylinder on the A4
  • BMW’s 3.0-liter DOHC I-6 Turbodiesel on the BMW 335d
  • Ford’s 3.5-liter EcoBoost twin-turbocharged DOHC V-6 in the 2010 Ford Taurus SHO
  • Volkswagen’s 2.0-liter DOHC Turbodiesel on the Volkswagen Jetta SportWagen TDI

“This year’s list of finalists symbolize the auto industry’s progressive movement toward achieving environmentally friendly vehicles, while making advancements in the areas of increased fuel economy, emissions reduction and performance improvements,” said Peter Marks, chairman, president and CEO, Robert Bosch LLC.

According to Bernd Boisten, regional president, Bosch Diesel Systems North America: “Clean diesel technology is one of the greenest powertrain solutions available today, providing a great fuel efficiency advantage, good resale value, a lower cost of ownership and tax incentives for consumers.”

Mindful that the industry seeks a variety of solutions and consumers appreciate having choices, Sujit Jain, regional president, Bosch gasoline systems, North America, pointed out the advantages of gasoline direct injection technology:

“Bosch’s gasoline direct injection technology embraces the need for smaller, more fuel efficient engines, while improving torque and performance. In collaboration with Ford, we supply a technology that is integral to the current family of Ford EcoBoost™ engines. We also teamed with Audi for the 2.0L TFSI turbocharged direct-injection 4-cylinder on the A4.”

Diesel Common Rail System Improves Fuel Economy and Performance
Bosch’s clean diesel engine technology includes electronically controlled high-pressure common rail and unit injector systems. Its advanced injection process improves fuel economy by more than 30 percent, reduces carbon dioxide emissions by nearly 25 percent and increases torque by 50 percent as compared to its traditional gasoline equivalents.

The Volkswagen Jetta SportWagen TDI engine uses the latest generation of Bosch clean diesel common rail system, capable of up to 2000 bar and up to five pre- and post-injections through piezo-electric injectors and realizes 140 horsepower and 236 pound-feet of torque, while delivering 29 mpg city and 40 mpg highway.

The BMW 335d features in addition to Bosch’s diesel common rail system the Denoxtronic with Selective Catalytic Reduction (SCR) technology, both of which are integral part of the overall injection and emission control system to aid in removing NOx emissions and improving efficiency.

The BMW 335d, featuring the 3.0-liter DOHC I-6 Turbodiesel engine, with 265 horsepower and 425 pound-feet of torque, can accelerate from 0 to 60 mph in 6 seconds while achieving exceptional fuel economy – 23 mpg city and 36 mpg highway.

Gasoline Direct Injection Increases Horsepower and Torque, Maintains Fuel Economy
Bosch’s second generation Motronic system for gasoline direction injection further optimizes the gasoline engine. The main components include the high-pressure fuel injector, high-pressure pump, high-pressure sensor and engine control unit. Through precise control of fuel injection and timing, the Bosch system increases horsepower and torque without sacrificing fuel economy. Coupled with turbocharging, the fuel economy can be improved by up to 20 percent when compared to a larger displacement port fuel injection engine.

Ford’s EcoBoost technology, powered in part by Bosch’s gasoline direct injection technology, is a gasoline engine that combines aspects of gasoline direct injection with turbocharging. The Ford Taurus SHO achieves 350 pound-feet of torque and 365 horsepower.

Audi’s A4 features Bosch’s gasoline direct injection technology combined with turbocharging generates 211 horsepower and 258 pound-feet of torque and is the best selling vehicle in Audi’s U.S. line up.
