ETHANOL - GOOD OR BAD? - How it Works | SCIENCE GARAGE

[@mateusoliveira8373]

Brazil uses ethanol powered vehicles since the 80's. Every car manufacted in Brazil must be able to run on gas and ethanol. Here our ethanol is made from sugar kane

[@almirjorge5462]

the only problem is that when the motor is cold is hard to burn the ethanol, i realy wish that the ethanol here uses 10% of gas like in the us

[@BlackCatRedScarf]

Adding 20% on ethanol allows even gasoline engines with modern ECUs to run on ethanol. Certainly not recommend if you don't know what you are doing, but on every racing engine that I opened, there is not difference in terms of wear... Except the gasoline engines got some thicker coal coating on the pistons and cylinders head. Ethanol is a blessing for racing car and much more healthy for people who like to tune cars or work on engines. In Brazil, the price per km can be better than gasoline, but that may vary due to ethanol vs gasoline prices on the pump and the efficiency of the ethanol vs gasoline (engines vary between 60% and 80% of the gasoline milage due to several factors). In US, ethanol isn't exactly a good deal outside the high performance automobiles spectrum.

[@ASPthespeedyboy]

Mateus Oliveira i’m going to brazil (This is a joke)

[@hqwthe]

but it doesn't matter because here in brazil we have flex fuel cars, cars with a balanced compression rate so it can run both gasoline and ethanol, which in practice doesn't run good in any fuel. in the 80' to the 2000' we had monofuel cars, gasoline or ethanol, then the difference mattered because ethanol was much more cheap

[@mateusoliveira8373]

@@hqwthe some better than others. I have a 2013 Honda Civic MT 1.8l it the efficiency compared to 'gas' is 83%

[@tvrsh_yuri]

The Gallons per Acre of land depends a lot on what vegetal you're using as a base for Ethanol. Here in Brazil we make Ethanol from sugarcane, it's fermentation process takes less time and you get about double the amount of fuel/land. Also, we have E-100 ethanol on every fuel pump, great for performance and costs about half the price of gas with about 3/4 of the mileage, so at least a good 85% of new vehicles here come with a flex fuel option (except for diesel trucks and stuffs like that).

[@Hartigan0809]

in brazil we use ethanol as much as gasoline, but we extract it from sugar cane and not corn. a few decades ago there were only-ethanol and only-gas cars, now almost all new cars are flex fuel.

[@modergav]

Great. In Europe we use E10 Gasoline. I have a Renault (in Brazil, Renault are popular cars) and I put ethanol E100, derived from sugar cane. No burning oil, no issues or something like that. Big like from Romania!

[@rafaelmoreir]

Here in Brazil I drive a 34 year old Mercedes which uses ethanol blended gasoline for about 27 years. From 15% in 1992 it has raised to 27% today. Not because I have a option (it's mandatory to gasoline here to have between 25 and 27% ethanol), but despite changes in the fuel hoses and a carburetor diaphragm, I don't have a single issue here. The car was once sat for about 4 months and started right away. The carbon build up is really low, the fuel tank is pristine and the carb actually has zero corrosion. But again, it's a carbureted engine, which I could fine tune it to perform with the same mileage to the european or US fuel. Friends with fuel injected ones blame a 30% drop in fuel efficiency. But my point is: Change your fuel hoses (as I would recommend to any old car driver) to a good ethanol-resistant one, advance your ignition timing a bit, maybe a colder plug and test it. I know it's not better than pure gasoline in overall performance but considering the benefits regarding less pollution, it's a very little compromise. Sad to know it's so expensive to make in the US.

[@cmte.brazinazzo2061]

Actually you don't need to use a cooler plugs if you didn't raise the compression ratio of the engine.

[@stefanobonaiuti8243]

unfortunately this is possible only in few places in the world, like Brazil where production of sugar cane and ethanol is cheap. I don't see how it could be done in other places like Europe or north america, unless super heavy subsidies (usa subsidize a lot the corn production, to get to 10% ethanol in petrol.)

Another point that speaks for ethanol is that you can manufacture it anywhere you can grow starchy crops. Which is basically anywhere humans live. Oil you have to find and have. Maybe not so relevant for the US, but if you depend on pipelines and huge ships to get your oil, it looks a lot more interesting. (Considering the ships probably do not use light oil extra de-sulfured, but rather whatever dregs are left in the refinery...)

[@Pornetini]

1:15 A very important distinction tho is that an enzyme is a catalyst, not a reagent. So it doesn't partake in the reaction, but it speeds it up.

[@StatusQuo209]

Ethanol with proper tuning is the bee's knees. Much better partial and full throttle power and even a smoother running engine. (Given you have enough injector) The MPG loss can be minimized as well because you can run a bit leaner partial throttle and also advance timing. I drove 60 miles on the freeway last week and got 33mpg on my B7 2.0T on E50.

Ethanol is actually amongst the simplest fuels. You can create it with water, sugar and yeast. You get the sugar from the corn, add the water and the yeast, fermented, distill it and you have ethanol.

[@stefanobonaiuti8243]

yep, that's how is made in Usa, but you could do it from a variety of sources that can be transformed into sugar and subsequently ethanol. In Brazil is done with sugar cane, but it could be made from every starchy or sugary crop; the main thing is that it has to be as cheap as possible, otherwise it won't make much sense.

@@cyjan3k823 producing ethanol from sugar cane is cheaper and more efficient than from corn. Sugar cane grows like a weed in Brazil, whereas the US has millions of acres devoted to growing corn. It's all about economies of scale. Corn is a less efficient input, but it's far cheaper to grow in the US than sugar cane. Brazil simply has the advantage in growing sugar cane and invested in developing the processes and industries for manufacturing ethanol from it cheaper than the US can.

[@calebshonk5838]

Ethanol does not negatively impact food prices, nor does it take crop space away from other crops. The corn used for ethanol production is "field corn", which is grown for livestock and isn't digestible by humans anyway. The fermentation process consumes the starches and leaves behind nutrients and protein which makes for a more nutritious feed for livestock. You also can't drink ethanol (even before it's mixed with gasoline), as it contains high levels of toxins and other chemicals that are harmful if swallowed.

[@ZacharySolomon0429]

Also, most of the time, at least around here in north western Illinois. We take the corn dust that's in the grain bins and around the other stuff then take it to the ethanol plant. Might as well be used for something rather than being burned off. That's what they used to do to corn dust.

[@emptyshirt]

Fuel ethanol actually stabilizes food prices. Excess production of feed corn in good years doesn't tank the price of corn because ethanol plants can just run at 100% capacity. In really bad years the ethanol plants run slower and there is still enough corn for the pigs and cows. Caleb, you are wrong about the edibility of field corn though, it can be eaten if it is converted into hominy. Also, fuel ethanol is safe to drink too. You might want to carbon filter it and distill off the methanol, but methanol can be broken down easily by the body if you drink a little of it.

If it's not equipped with flex fuel sensors, etc. it'll run poorly if you mix more than 15% ethanol content. The effective octane rating of the fuel in your tank will go up, but your ECM will have to adjust the mass flow from injectors to compensate since ethanol has about 2/3 the combustion energy density of gasoline. BTW most E85 sold at gas stations isnt exactly 85% ethanol. there is always some variance to ethanol content. Some gas stations will have 70% some have 82%, etc. The content matters because fuel maps will need to be calibrated based on how much ethanol is in the fuel mixture.

nothing except better performance. I've run my BMW on full ethynol E85 for almost a year and its fantastic. Those who say otherwise have never used it they just repeat information they hear or read from unreliable sources.

[@alextheonewarrior]

Precise timing and high compression also increases efficiency does it not? Modern engines could run up to a 12.1:1 compression ratio on E85 while current E10-E15 usually run a 9.4-10.1 compression ratio. Higher compression means more heat and more heat means more efficiency, precise timing also means more efficiency and both of those also increase power gains, on top of that, eco-boost cars could run more boost to save on fuel economy.

Science Garage these days feels like "Keep it down in the Science Garage, the baby is sleeping in the next room over" - I don't know if this was a production decision or Bart is just feeling low on energy or what, but it's just not the same. :\

Noticeable, yes but still just as informative and interesting. You can clearly tell who’s the grownup in the Donut trio.

A bit sad when he says compression engines like my hapiness a thing of the past but also funny. I think he can make a joke out of sad

If you don't have a flex fuel vehicle you don't have the proper rubber seals or plastics. Don't use it.

[@Haloruler64]

Flex fuel isn't an issue of rubber seals, it's an issue of engine management and sensors. Modern fuel systems can support E85 just fine, but they need to be tuned for it.

[@ExileXCross]

Also most car engines have long switched from fiber/cork gaskets to exclusively multi-layered steel (MLS) gaskets a long time ago to the point where that is more of a falsehood than a truth. To ballpark, If it was made after 2005, chances are that a tune is the issue.

[@StatusQuo209]

@@Haloruler64 Yup. You are absolutely right.

[@TheMrFlyBoy18]

Its possible to run E85. You would have to upgrade the fuel system components and get a tune for it. But if you’re saying just a regular car and the owner tries to put in E85, yeah thats a big hell no. Don’t ever do that.

Bart, i told your wife you coming to NY next weekend!

[@friskoskiez3761]

Depending what your car was made for, E-85 helps out LATER in the process. First modifications towards leading E-85 is a full exhaust system, starting with the headers, than a tune, a better intake filter, THAN E-85. Not doing this is a waste of fuel with minimal power gain. This fuel is awesome, but not when the weather is cold.

I have a 2000 and 2001 truck/car put ethanol free gasoline in both vehicles everything has improved. Gas mileage, overall performance,engine temperatures, reduced idle rpm’s, same Highway speeds at lower rpm’s- drive exact 260 mile route round trip 3X week . Use all grades from 87 thru 91 octane rates.

[@iviaverick52]

One other point is that ethanol absolutely demolishes typical engine seals, especially in older vehicles. If you love having a big 'ol puddle of oil in your driveway on a regular basis, use E15. If it wasn't for that fact, it would be a great consideration for a lot of folks.

[@Drzika8000]

Here in Brazil ethanol is obtained by sugar cane fermentation This process is make in really large scale So, most of the new cars sold in Brazil can use ethanol, gasoline or both at the same time This usage in large scale begined in the 2000's when the governament started do incentivate the usage of a fuel that coud be used on most of the new cars and wasn't so dependent on oil price due to the oil crysis

[@karlwashere123]

My car gets significantly better gas mileage when I avoid ethanol

[@3O2MuStAnG]

That's normal as ethanol naturally burns more efficiently than gasoline. You still save money as ethanol is a lot cheaper depending where you live while increasing the power potential of your engine. It's good for the environment, too.

[@karlwashere123]

@@3O2MuStAnG I have a turbo kit on a 3.5 VQ Putting 349 down at the wheel. Not only do I get valve chatter during cold start ups with ethanol but sluggish pedal response all around. And although the price is negligible when comparing the two types of gasoline almost all ethanol laced gas in my area is 15%.

[@atomicmillenial9728]

OneTT It really does depend where you live. In Australia E10 is the "cheap" fuel and is generally avoided since most cars run like ass on it. E85 on the other hand is fairly uncommon at the pumps and is usually 40-50 cents MORE expensive than petrol.

[@Sandi_shores_lands_fish]

@@atomicmillenial9728 is it a question of whether the cars poor performance on that fuel can be tuned to run ok

[@jeep13ca]

The better mileage is due to the fact that the power density of ethanol is lower than that of gasoline. So to get same amount of heat out of the fuel you need to use more of it.

[@joekoy7495]

As an owner of a 1971 Datsun 240z (twin carbs) Efuel is a disaster, when the fuel is fresh the cars starts and runs just fine however, if I let it sit as little of 2 weeks the fuel becomes useless, the car refuses to start properly and once started it will not run properly, it refuses to idle and drive as it should, I have to drain the gas and put fresh gas into it , problem goes away, strangely, fuel injected cars are not effected by the same problem. Also, I noticed that my fuel filter (the reusable cleanable glass job) keeps getting clogged with what can be described as a very fine mud...color is tan, not sure what that is all about. I'm in Las Vegas so water absorption from the air should not be an issue, As the car is not a daily driver I do not keep any fuel in it, I put in couple of gallons at a time when its to be driven. Its a PITA but it is what it is.

[@americansmark]

Put E15 aka Unleaded 88 in my car yesterday and set off the emissions CEL. GM says I can run it, but it still freaks out the system. Gonna switch to E85 this summer so I can make more power.

[@jerkimerjames3545]

I'm the nerd here. We have to make ethanol as a byproduct of feed for livestock and inputs for many Agra chemicals. Washer fluid, de-icing chemicals, feedstocks for thousands of products. If we used more ethanol for transport, it would help our obesity epidemic. The tech is here now but it takes leadership to balance out our resource consumption.

Here in Brazil ethanol is made of sugar cane and is as common as gas, so every car that is built here has a corrosion protection, since all of our gasoline has some ethanol in it. The more you know *rainbows

[@spencertaylorcrowe]

E85 turns my 2010 ford escape 3.0l Dohc v6 (flex fuel) into a freaking beast. The fun part is when the rpms get into 4k range it feels like it's taking off like a jet 😂
