  1. Per ASTM 5798-11A approved this year, the current range of ethanol content can be 51 to 83 percent ethanol. What can be up to that 49 percent non-ethanol make up can be anything the rack wants it to be as long as the fuel meets RVP. No consideration for performance or emissions was given and the reason the ethanol industry supported it was stated as "we are going to take away the oil companies excuse for not blending E85". "Hydrocarbon blendstocks for meeting ethanol fuel blends performance requirements are unleaded gasoline, gasoline blendstocks for oxygenate blending (BOBs), natural gasoline or other hydrocarbons in the gasoline boiling range." This leads to a combination of products that can boil at room temperature to high distillation gasoline as long as vapor pressure can be achieved.
  2. We have a gift right now that we are exporting at a rate of nearly 1 billion gallons of ethanol. The writing is on the wall that RFS II may see new limitation attached and we need to take a serious look at how we approach distribution. We as an industry need to push for changes in how ethanol is blended in the market place. We have OEM's asking for more octane in the market yet we have the EPA saying they plan to remove E10's one psi waiver. We have ASTM requirements that conflict to intermediate blends yet no one at RFA or Growth will listen to these issues. We need to collectively demonstrate that the RVP swing of ethanol with in one PSI of base gasoline has less effect on emissions then the fact that oil companies are allowed to dump high distillation components. It is beyond reason that the EPA will not grant the 1 PSI waiver for E15 or intermediate blends in general. Is this the doing's of the oil industry to control the ethanol market. It certainly looks that way. We need to show the benefits, especially for health effects that any blend from E15 to E85 and then support what will win in the market place.
  3. Advanced Biofuels wrote the article from the data we had collected and provided.
  4. We all know we can see higher power output from E85, much of this comes from the cooling effect as well as octane. One has to ask, how do we become more competitive in the market place with ethanol. There is value for E30 today but the full benifit comes if OEM's plan for it. E30 can offer the same mileage but now we can also compare E30 to better then Premium performance. This attachment is not saying we stop asking for FFV's that can operate up to E85 blends but we need to offer the OEM engineers a fuel they can plan for, both for emissions and efficiency reasons. We also need to collectively put forth a strategy that can change the policies at EPA and DOE. Welcome any feedback. 393_.pdf
  5. Several states have held up blender pumps as issues are brought up by state regulators. There is testing under way that would be helpful for octane labeling. We could address the concerns and start at a point that offers the best solutions allowable with in today's regulations. The blender pump could still pump E98 as well but may need special device or code to allow. I think you would be surprise how many hot rodder's and racing teams avoid E85 today because they fear what is in that 15 to 30 percent gasoline mix. Here we have found winter blends still in the tank in June. How can these guys appreciate ethanol when they continue to have various results.
  6. What we need is a strategy that even the oil companies can't put holes in. We offer a fuel blend choice that consumer would appreciate, the right information like recommending consistant fueling to offer the best mileage result and information that by dilution, we are displacing the components of gasoline that have a significant health effect issue. The highest blends to offer initially is E60 winter and E70 summer. The reason is that at some point, API and others will contend we are selling fuel with to low of RVP. By knowing our limits and offering consumer a fuel with good RVP and performance we can avoid a vehicle that may not have been fully adapted to a new fueling prior to cold start. We also are giving all the octane the vehicle needs to maintain best spark timing while giving them a little more energy in the tank by blending actual gasoline. I see that the average FFV vehicle would only see a mileage loss of no more the 10 percent at E60. At 10 percent mileage loss with E60 and at today's prices, ethanol could compete even if we lost most tax credit.
  7. What would the public say if it can be demonstrated that the lack of EPA attention on RBOB has allowed the oil companies to actually produce a gasoline prone to higher emissions as long as ethanol is added. One should ask why US gasoline tested rather poorly in a world wide study that tested over 1440 gasoline samples and found the US near the bottom of the barrel. Time to argue ethanol is a fuel and not an additive.
  8. Has anyone notice the huge upswing in the media about ethanol burns hotter. This newest push started right after API and thirty some companies signed a letter sent to the EPA. Just Google "ethanol burns hotter October 2010" as see the trace. This statement is so out of context of the E15 testing yet there is certainly a push by ethanol critics to see this gets repeated as much as possible. If people hear it enough times, they will believe it. What I find interesting is that SEMA has followed suit. Contact the corporate headquarters and continue to get sent back to their DC office. So much for SEMA being for the consumer, they have no interest in putting out information that can help the industry.

    The main product of combustion that gets all the criticism is acetaldehyde. This VOC/HAPs like all VOC's is the product of incomplete combustion. Two ways to improve this emission is to put back in the ethanol sensor. Significant amount of overfueling occurs during cold start in order that the driver has a quick start up. The value of direct injection is that injection during the compression stroke can also reduce the amount of overfueling and multiple SAE papers have shown catalysis temp and activation occurring equal to optimized gasoline cold start. I still find it interesting that though ethanol has one key emission that gets all the attention, ethanol reduces 85 gasoline VOC's to near zero by E75. Ethanol in one study shown 10 identifiable VOC's By the way, Acetaldehyde is listed as a HAP yet if you like a beer or glass of wine, your body produces Acetaldehyde and if you have fruit on your kitchen counter or grill hamburgers, you expose yourself to this compound.
  10. Has anyone really looked into current E15 testing. Is ethanol being tested as an octane enhancer, an addition to gasoline or as an octane displacement being that ethanol is added to a cheaper gasoline. For emissions, why is ethanol compared to Indolene rather then consumer intent gasoline. It is interesting that the ethanol industry is not able to have access to the testing program with fuel breakdown but per the monthly report by SWRI, there are multiple oil companies listed each month.
  11. The nice thing about this higher fuel pressure, ethanol will look even better. One concern by engineering is if particulate emission become regulated even for spark ignited engines. While PM goes up with DI and gasoline, Oakridge demonstrated on a GM Ecotec engine, e20 reduced PM by 40 percent. A GM study shows that the injection timing is much narrower for gasoline at high loads and that E85 had nearly twice the allowable range of crank angle available. Most importantly though is that with higher fuel pressure, several studies show that if E85 is injected during the compression stroke, catalysis light off was equal to gasoline at much less fuel enrichment. Along with this also comes what MIT and other have demonstrated, little to no fuel enrichment at wide open throttle with E85 because we get the full value for the 4X's cooling effect you can get with DI. This will significantly reduce cold start emissions and make an all around reduction to emissions with ethanol. This should shut up them critics from Standford.
  12. I suggest talking to Dan or Chris at flexfuelus.com. What they are seeing by installing the ethanol sensor that the OEM's removed years ago, is getting good result. They have certification on several engine platforms and fleet applications like police cars is a great way to promote the value of any blend up to E85.
  13. This comment from an article on automotive.com should be stamped “give me a break”. *Replace the fuel in your tank every few weeks if not driving the car. Gasoline has a long shelf life, but ethanol blends have a shelf life of approximately 90 days, after which components begin to separate. Exposure to moisture speeds up the process.
  14. Remember, this vehicle will most likely be premium fuel only, we just gained 20 cent on the price spread. If they followed GM's own study from 2008 then the cold start emissions will see significant improvements and just like the 2006 Saab FFV, no to very little fuel enrichment at WOT. This should be demonstrated as soon as possible for both efficiency and emission benefits.
