In order you raised the points. Fuel has BTU's not calories, possibly kilojoules, but definitely NOT calories. But if the water entrainment was 0.5% I probably wouldn't be worried about it but it's more like 5.0% (or a bunch more, see below) on average.
Wrong:
I can convert gasoline to any energy form I want. Watch me: 1 gallon of gasoline = about 31470 calories orrrrrrrrrrrr about 115,000 BTU's orrrrrrrrrr about 1317600000 jules. In fact, someone even
makes a nice little calculator
+of+automotive+gasoline/to/calorie+[nutritional]]for doing this.Phase separation does NOT require a particular temperature range or time frame. It is caused by exceeding the point at which the fuel blend (10% Ethanol) can no longer absorb any more water, but the ethanol can still absorb more water and it's available to be absorbed. When that threshold is surpassed the water-laden alcohol drops out of solution with the gasoline. At that point you no longer have 50 gallons of E10 in your tank, you have 45 gallons of E0 gasoline and 5 gallons of straight, albeit water-laden, Ethanol. When that hits your engine, the fertilizer hits the rotary air circulation device.
Wrong:
Phase separation occurs at a much lower temp between gasoline and alkie.
See figure 1 about phase separation for how wrong you are. If you read the entire article you will find out how little water E10 will hold. Holding water is a good thing in small amounts BTW. Straight gasoline can hold very little water so if you have any water in your straight gasoline it will phase separate and your engine will quit. Where as E10 will not and the water will pass harmlessly through your engine.
Speaking of the math being really that simple.....
If you get 20 mpg on straight gasoline (we're talking average everyday vehicles, not the very few RV's percentage-wise) but you lose just 10% (2mpg) of that (the typical real world experience of most people is 15% to 20%) on 90% gasHow much smog do little engines put out?oline / 10% ethanol a
nd you drive 1,000 miles you will use (1,000 miles / 18 mpg) 55.6 gallons of E10, which is 5.5 gallons of ethanol and 50.1 gallons of gasoline.
If however you'd got that original 20 mpg you would have only burned (1,000 miles / 20 mpg) 50 gallons of gasoline.
Except now you've burned 0.1 gallons MORE gasoline PLUS the 5.5 gallons of ethanol.
Can you please explain how burning MORE gas than before PLUS an additional 5.5 gallons of ethanol can possibly help with 'cleaning up our air' any?
Simple:
#1. You don't loose 10% as you and some people say they do. It's 3 to 5% just as I have said all along. Dyno readings have proved this over and over.
#2. Cleaning anything takes energy. To run the "air cleaning" (Cat, Air pump, EGR, ect) systems on an engine is no different.
I can tell by your last question you have never ran a smog machine. Do you really think that we have not made strides in air pollution in the last 50 years?
I had to smog my BMW and the machine measured 0 HC's coming out of the pipe as idle. That is ZERO!!! Yes, these new cars ARE that clean!
Now try this with a 3 HP lawn mower and see what happens. The needle will be pegged and then some. Your 3 HP lawn mower puts out many times more smog then my 235 HP BMW.
How much smog do little engines put out?LinkIf you don't believe me just look at a car with a cat on it. A car with a cat on it will use more gasoline because they need energy to make them work. Using your logic the car with no cat will produce less air pollution. If you believe that just cut the cat off of your car and take it down to be smogged and see what happens. LOL
Let me close by saying I'm no alkie fan. Not at all. But all of the wrong info being put out by a few is very disturbing.
