Trends: Bosch Contributes Key Technologies as Engines Become Smaller, More Powerful

Bosch’s Gasoline System Technology Featured on 9 of Ward’s 10 Best Engines for 2012

tFARMINGTON HILLS — With automakers squarely focused on meeting the 2025 CAFE regulations and consumers wanting more miles per gallon and lower emissions, Ward's 10 Best Engines of 2012 indicate the direction in which the automotive industry is headed – smaller, turbocharged engines with direct injection.

tBosch technology is featured on nine of the 10 Best Engines of 2012, and its direct injection technology appears on five of the winning engines.  The main elements of the Bosch direct injection system include the engine control unit, high-pressure pump, and high-pressure fuel injector.

t"Direct injection is a key technology in current and future engines, and we remain committed to developing the most innovative and advanced engine technologies," said Sujit Jain, regional president, Gasoline Systems North America, Robert Bosch LLC. "Providing advanced technologies, such as direct injection and turbocharging, are essential in helping automakers meet the demand to bring the most fuel-efficient vehicles to market."

tBy 2016, the number of highly efficient four-cylinder engines will increase by 20 percent to more than 20 million units globally, according to Bosch Mahle Turbo Systems, a joint venture between Bosch and MAHLE that produces turbochargers for passenger cars and commercial vehicles. "Based on this trend data," Jain said, "the forecast is clear: In the near future, every automaker will offer turbocharged gasoline engines."

tIn addition to direct injection systems and components, other Bosch technologies including port- fuel injectors, throttle body, oxygen sensor, mass air flow sensor, and other key sensors, to the various winning engines:

  • tt5.0-liter DOHC V-8 (Ford Mustang Boss 302)
  • t

  • tt2.0-liter EcoBoost DOHC I-4 (Ford Edge)
  • t

  • tt2.0-liter TwinPower Turbo DOHC I-4 (BMW Z4/328i/528i)
  • t

  • tt3.0-liter TwinPower Turbo DOHC I-6 (BMW 135i, 335i, 535i, X3)
  • t

  • tt3.6-liter Pentastar DOHC V-6 (Chrysler 300S/Jeep Wrangler)
  • t

  • tt2.0-liter Skyactiv-G DOHC I-4 (Mazda3)
  • t

  • tt3.0-liter TFSI Supercharged DOHC V-6 (Audi A6)
  • t

  • tt2.0-liter Ecotec Turbocharged DOHC I-4 (Buick Regal GS)
  • t

  • tt1.6-liter Gamma DOHC I-4 (Kia Soul, Rio/Hyundai Veloster)

tDirect Injection Improves Fuel Economy, Reduces Emissions
tAs automakers strive to reach new CAFE standards of 54.5 mpg by 2025, Bosch's high-precision injection technology allows vehicles to consume less fuel and produce fewer emissions without sacrificing torque performance. This technology, coupled with turbocharging and variable valve timing, can lead to as much as 18 percent reduction in fuel consumption and emissions.  In combination with additional technology packages and extreme downsizing, Bosch aims to achieve a 30 percent fuel efficiency improvement for the gasoline engine. Bosch anticipates that in 2020 U.S. sales will reach 16.3 million vehicles, with 39 percent featuring gasoline direct injection.

t"This lineup of engines honored by Ward's goes a long way toward changing customer perception about the relationship between engine size, fuel economy and power," Jain said. "These smaller engines are, in fact, powerful as well as fuel-efficient."
