Each year, Bosch spends more than $5 billion for research and development, and applies for some 3,800 patents worldwide. Some of the company’s latest innovation or technology advancements have been applied to key powertrain technologies to multiple vehicle named to Ward’s 10 Best Engines of 2010 list, including the popular and our favorite BMW 335d.
Bosch has been a key player in the automotive industry for years and the range of partnerships extends across a wide net of automakers around the world, from BMW to Audi, Ford, or VW, just to name a few.
One area where Bosch has continued to focus on was clean diesel. Vehicles powered by clean diesel benefit from 30 percent better fuel economy and up to 25 percent reduced emissions.
Award-winning engines featuring Bosch technologies include the 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 and Volkswagen’s 2.0-liter DOHC Turbodiesel on the Volkswagen Jetta SportWagen TDI.
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. As we have seen on the BMW 335d or X5d, the tax credit is up to $900 for the sedan and up to $1,800 for the diesel SAV.
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 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 achieves exceptional fuel economy – 23 mpg city and 36 mpg highway, while maintaining the dynamics and sportiness of a BMW, due to the increased torque.
Gasoline systems have also benefited from the latest research and development. Engines using Bosch technology continues to be more efficient, while improving torque and performance.
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.
For years, the focus seemed to have shifted towards hybrids, but recently diesel powerplants are capturing more attention and acceptance from a significant number of U.S. consumers who, when provided the option, are choosing diesel, due to equal or better fuel economy.[Photo by TheDieselDriver ]
