Urban Air Initiative: Ethanol Reduces Engine Wear
by Joanna Schroeder (DomesticFuel.com) The Urban Air Initiative (UAI) has released a study that finds ethanol free gasoline blends actually increase the wear and tear on engines including hoses, seals and fuel tanks. In other words, the data supports ethanol blends lead to cleaner engines. The findings were presented at the semi-annual meeting of ASTM by Steve Vander Griend, technical director for UAI who also works for ICM.
The report demonstrated that high aromatic content of gasoline, including toxic aromatics like benzene and toluene, negatively impact engine parts. Vander Griend explained in his presentation that the toxic aromatics create a significant increase in the escape of harmful emissions that can have a devastating impact on public health as these are considered by the Environmental Protection Agency has known and suspected carcinogens.
“What we are seeing is that benzene and toluene are increasing permeation, which means increasing the amount of fuel vapors that seep from a vehicle. For anyone who has a garage at home and smells gasoline, vapors are escaping through the vehicles fuel system or small engine gas tank,” said Vander Griend.
Also during his presentation Vander Griend explained that extensive testing was conducted on fuel lines, gas containers, and plastic components. The materials were each soaked in straight gasoline (E0) and a 10 percent ethanol blend (E10) for extended periods of time. In every case, said Vander Griend, the ethanol free gasoline increased the damage to fuel lines, gas containers, and plastic components, while the materials soaked in E10 were impacted less.
ASTM said it will begin to study the aromatic levels of gasoline. READ MORE and MORE (Ethanol Producer Magazine)
Excerpt from Ethanol Producer Magazine: To better visualize the damaging effects of straight gasoline, click here to watch a time lapse video involving a simple Styrofoam cup. The E10 blend contained 20 percent aromatics and had a slower impact on the cup. The E0 blend, with 26 percent aromatics, instantly destroyed the cup. While not as scientific as soak testing, the results are similar. READ MORE
Hybrid, EV Sales Tumble in 2015
by David Shepardson (Detroit News) Sales of hybrid and electric vehicles fell sharply in the first half of 2015, hurt by low gas prices, fewer incentives and a broader market shift away from cars.
This is shaping up to be the toughest year for electrically powered vehicles since General Motors Co. and Nissan Motor Co. launched mass-market advanced vehicles in 2009.
A new Georgia law takes effect this week that ends the $5,000 state tax rebate on EV sales and adds a $200 yearly registration fee for EV owners to pay for road repairs.
Despite hefty discounts, low gas prices and aging EV models are helping to drag down sales of fuel-sipping plug-in electric hybrids and full-electric cars. They are also being hurt by a consumer shift away from cars toward crossover and sport utility vehicles.
Chelsea Sexton, a long-time industry consultant and electric vehicle, advocate, says a big reason for the slow down is “aging models” and “anticipation of fall updates than gas prices or market interest,” Sexton said, saying it is not a surprise and may not fully rebound until 2017 as California mandates will boost industry offerings.
