At a clean diesel event in California, Robert Bosch Corporation predicted that the US market for light diesel vehicles will reach 15 percent over the next 10 years.
Advantages offered by today’s diesel passenger vehicles, in comparison to conventional gasoline vehicles, include an average increase in fuel economy of 30%; a decrease in carbon dioxide emissions by up to 25%; and an increase in torque of up to 50%.
Bosch will support this growth through continuing to provide advanced diesel engine technology, such as fuel injection and aftertreatment and engine management systems.
Diesel gives consumers the fuel economy and performance they desire. At the same time, diesel provides the means to decrease carbon dioxide emissions and reduce dependency on foreign oil—issues of particular importance in the California market.—John Moulton, president, powertrain division, Robert Bosch Corporation
According to a model developed by the US Department of Energy, if diesel vehicles make up 30% of the US market share by 2020, the US could reduce its consumption by 350,000 barrels of oil a day (about 1.7%).
Seventeen diesel vehicle models are currently offered for sale in the US today, including entry-level cars, SUVs and pick-up trucks, a 55% increase in availability since 2000.
US demand for diesel passenger vehicles is expected to grow stronger after Tier 2 Bin 5 emissions standards take effect next year. Diesel passenger vehicles will meet the new standards through a combination of ultra-low sulfur fuel (available nationwide in October) as well as advanced fuel injection and aftertreatment technologies.
Bosch recently announced plans to launch dosing units and control concepts for selective catalytic reduction (SCR) systems in 2008. These systems will assist in removing NOx emissions, enabling diesel vehicles to meet the US Environmental Protection Agency’s (EPA) Tier 2 Bin 5 emissions standards.
