A new study by the Center for Integrated Manufacturing Studies at Rochester Institute of Technology indicates that the use of E20 fuel, which blends 20 percent ethanol with gasoline, reduces the tail pipe emissions of hydrocarbons and carbon monoxide, compared with traditional gasoline or E10 blends.
The data illustrates the potential benefits of E20 as a tool in reducing overall vehicle emissions at a time when many states and the U.S. Department of Transportation are considering policies that would increase the ethanol percentage in standard gasoline.
“Currently, numerous commercially available gasoline brands contain 10 percent ethanol,” notes Brian Hilton, senior staff engineer at the center, a component of the RIT’s Golisano Institute for Sustainability, and part of the research team. “There have been concerns raised that any increase in blend would negatively impact standard internal combustion engines, however our data shows that vehicle performance remained constant, while carbon monoxide and hydrocarbon emissions were decreased even over E10 blends.”
The RIT team, which was also led by Brian Duddy, a senior program manager at the Center for Integrated Manufacturing Studies, worked with the County of Monroe, N.Y., to test the use of E20 in 10 older gasoline vehicles that were not designed for ethanol fuel mixtures. The study utilized service vehicles used by the county, which logged over 100,000 miles on E20 fuel and were analyzed periodically both for emissions and overall wear and tear on the vehicle. The fleet showed an average emissions reduction for carbon monoxide of 23 percent as well as a 13 percent reduction for hydrocarbon emissions, compared to conventional gasoline, with no measurable stress on vehicle operation or mechanics.
The study results were published in the Journal of Automobile Engineering and are being used by the Environmental Protection Agency to promote the federal Renewable Fuel Standard program. This effort has mandated an increase in the volume of renewable fuel required to be blended into transportation fuel from 9 billion gallons in 2008 to 36 billion gallons by 2022. The RIT team is continuing to work with Monroe County to convert their entire conventional gasoline fleet to E20 and will provide additional analysis on the impact of ethanol on long-term vehicle durability.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
