Heavy Trucks & Buses
Freight-hauling heavy trucks consume a significant portion of any country’s annual fuel needs. With rising fuel prices, truck manufacturers are under ongoing pressure to improve fuel economy.
At the same time, trucks contribute a large portion of vehicular pollutant emissions. With significant public concern over greenhouse gas and other pollutant emissions, truck manufacturers are being pressured to drastically reduce tailpipe emissions. In 2010, the U.S. Environmental Protection Agency (EPA) enacted highly stringent emissions standards for trucks, and the European Union will implement tightened standards (Euro-6) at the beginning of 2013.
The bus sector is growing as well, primarily due to rising public transportation needs in emerging economies — such as China, India and other developing countries — and renewed interest in public transportation in developed nations, such as the United States. Like truck manufacturers, bus manufacturers face pressures to reduce tailpipe emissions and fuel consumption.
To address these issues, truck and bus makers as well as suppliers are busy developing technologies such as selective catalytic reduction (SCR) and diesel particular filters (DPF). At the same time, they are working continually to optimize diesel engines to reduce emissions and fuel consumption. Organizations are researching completely new technologies, such as opposed piston engines, that show great promise. Rounding out the list are hybrid–electric powertrains and fuel cells, particularly in the bus segment: Driven by green initiatives, many cities are incorporating environmentally friendly electric buses into their municipal fleets.
Whether the application is SCR, opposed piston engines, hybrid–electric powertrains, fuel cells or optimized aerodynamics, ANSYS is ready with powerful and validated tools to solve technically advanced leading-edge engineering problems.
