    Hello, I have recently been tormented by the question whether alcohol can be used instead of gasoline, I read the article ----> http://www.drewnozamiastbenzyny.pl/alkohol-zamiast-benzyny/ and concluded that you could drive on alcohol.
    What do you think about it?
    Has anyone already tried to drive on alcohol?
    Regards.

    Hello .
    Alcohol instead of gasoline is widely used, probably the most in South America - all in all, it is a good, relatively ecological fuel. :D

    Of course it is possible, I will say more ethyl alcohol is a better fuel than gasoline, not long ago I saw on TV how Saab engineers made a comparative test of a car running on gasoline and alcohol. In the latter, the ignition was shifted accordingly because alcohol has a higher octane number. They put two cars next to each other and raced, conclusions - gasoline had no chance!

    Ethyl is also suitable.

    Once a strong agri-fuel lobby is formed, oil exhaust gas will be more carcinogenic :|

    Niemiaszki as their allies cut off robbery.
    As well as on coal fuel, gasified wood etc.

    Hello .
    The old-fashioned way - in winter it is good to add a bottle of denatured alcohol to the tank. Contrary to gasoline, alcohol mixes very well with water and it can save us from unpleasant surprises. :D

    Well, that's how it was on TV yesterday. They converted beer wastewater into ethanol.

    "The cost of producing 1 liter of bioethanol fluctuates around PLN 2.5. It is interesting that the cost of producing one liter of diesel oil costs around PLN 1.80 at a refinery"

    Everything is nice, you can run on ethanol (Brazil and Beetles are produced as adapted to drive this fuel) but do you know what the social costs will be after switching to this fuel?
    Do you know how much the price of food has risen? After all, this alcohol has to be made from something, and today it is easiest to make from potatoes, beets or grains.

    Recently I saw crosses run on alcohol they have an amazing shoe compared with gasoline no chance with alcohol in the program they only said that you need to make small modifications such as increase the nozzles, set the right lead angle and reduce the air dose because alcohol needs less air than gasoline.

    Of course, you must remember to increase the clearance between the piston and the cylinder so that they do not seize.

    Well, but with partial engine wear, you don't have to.

    Dear colleagues, I recommend reading that you probably do not know:
    http://www.zss.lublin.pl/html/motor/20.%20Paliwa%20silnikowe.pdf
    Methyl alcohol is only half the calorific value of gasoline, and ethyl alcohol is 2/3. This means that to drive the same distance at the same speed, you need to use 2 times more methyl alcohol, or 50% more ethanol than gasoline. The addition of 5% ethyl alcohol to gasoline increases fuel consumption by about 8%, and the 5% addition of methyl alcohol to gasoline increases fuel consumption by 10-12%.
    Additionally: both engines and fuels have come a long way of matching, and an engine optimized for gasoline will perform significantly inferior to other fuels - including both power loss and shorter service life.
    Brazil used a mixture of ethyl alcohol, but for this fuel, engines were specially produced there.
    As for the different ideas of alternative fuels enthusiasts: I suppose most of the forum participants have secondary education, so they probably can calculate (from stoichiometric equations) what is fuel consumption, air consumption, CO2 production and other such trifles. Why is there such a great reluctance to take advantage of basic school knowledge? Are you deliberately leaving "backlash" for cheaters and freaks?
    So far, the basic laws of physics and chemistry have not been abolished, despite many attempts by those who somehow did not learn these laws.
    Enthusiastic statements about "fantastic performance" remind me a bit of the advertisement of a calculator seller: "buy our calculators, only with us 2 times 2 is 5!" ...

    Rzuuf, there are serious mistakes in the descriptions in your link.
    One example would be the statement in the first sentence.
    It would result in the cooling of the internal combustion engine being a decrease in efficiency.

    The thermal energy of combustion is only part of the engine's energy.

    Added after 6 [minutes]:

    Take detonation combustion (which harms engines), but causes more power, despite the fact that the heat energy is the same.

    Added after 3 [minutes]:

    Explosives also do not obtain all their destructive power from thermal energy.

    J. Kleban!
    If you have "competitive" and reliable data, I'd love to know it.
    I don't see the error you're talking about:
    Using Alcohol as Fuel Alternative: Experiences & Possibilities - Ethanol vs Gasoline
    I do not know how this sentence may suggest that the engine cooling causes a decrease in its efficiency. This is some new, unknown theory? Did you dump the radiator in your Maybach and it started to drive like a Ferrari?
    You write that thermal energy is only part of the engine's energy. How big part? Where does "rest" energy come from? Is it possible to run the engine with this "rest" without fuel? That would be a brand new Perpetuum Mobile! So far, scammers or fools have the sole share in promoting "PM", maybe you will finally make a breakthrough?
    Why do you think detonation combustion gives more power if all engine and fuel manufacturers are trying to optimize both fuels and engines so that detonation combustion does not occur? Do you know a secret of fuels and engines that is unknown to their manufacturers? Or is it another unknown new theory?
    If you know what explosives get their strength from, why not share this knowledge as well? I read somewhere that the energy that can be obtained from burning 1 kg of coal is several times greater than from 1 kg of dynamite!
    I searched, found: coal - 27MJ / kg, and dynamite 3MJ / kg - comes out 9 times ...
    However, if your "revelations" do not have any basis in documented knowledge, and are only your guesswork, then do not let people raspberries, as this is an offense against the Electrode Regulations.

    Hmm, I don't know what the point of your argument is, it goes far beyond the topic. The topic clearly asked whether you can drive on alcohol, it was explained, the obvious fact is that it is possible and you can get much better results even after minor modifications than with gasoline, it is forbidden in our country, but there are countries where it is normal for he drives it, so I don't know why throw some coal or dynamite into the topic and argue about what ???? If you want to argue, it is better what to do to make our beloved government let people live.

    Rzuuf Tell me one thing, can the temperature alone (heat of combustion) increase several times the volume of gases in the combustion chamber?
    Read about the principle of operation of internal combustion engines before you write anything like that.

    Added after 26 [minutes]:

    As you can see from the link, this is a PDF from the basic driving school in Lublin and you should explain to the instructors of this school that they duplicate the error (wrongly formulated sentence)

    The engine energy comes from the change of the volume (several times) of combustion products (exhaust gases) in relation to the volume of fuel and oxygen used for combustion, supported by the combustion heat.

    Added after 13 [minutes]:

    In other words, ... the exhaust gases formed after fuel combustion at atmospheric pressure have several (or even several) times greater volume (depending on the fuel) than the fuel and oxygen from which they were formed, so by burning them in the engine compartment, they cause a sharp increase in pressure, and with the participation of the heat of combustion, this effect is magnified, causing an even higher pressure increase.
    So do not write that the heat of combustion is the main source of energy for the internal combustion engine.

    Alcohol is also used to purify tap water from nitrates. It is transported by tanker trucks to treatment plants and is one of the cheapest options.

    However, minor modifications such as switching the ignition or changing nozzles may not be enough to achieve better results. With a lower calorific value of spirit but a higher octane number, the compression ratio would have to be increased and I don't know if raising it to the maximum for this fuel would be enough?
    Maybe these much better effects are achieved with nitro-methanol (Nitromethane)?

    >>7436811 I live in Brazil and here every petrol station sells ethanol which is cheaper than petrol and all cars and motorbikes have been flex fuel here for years, I myself drive on ethanol and the fuel consumption compared to petrol is subtle and does not affect the economy as ethanol is about 1.20 zloty cheaper, manufacturers report higher consumption of ethanol by about a percent but also higher power, but these are also insignificant differences unless someone drives competitively on public roads and streets. For the record, there is no ethanol-blended petrol here - pure ethanol made from sugar cane. Regards

Topic summary

The discussion centers on the feasibility of using alcohol, specifically ethanol, as an alternative to gasoline for fueling vehicles. Participants share experiences and insights, noting that ethanol is widely used in South America and can be more environmentally friendly than gasoline. Ethanol has a higher octane rating, which can lead to better performance in modified engines. However, concerns are raised about the cost of sourcing alcohol, potential health risks associated with methyl alcohol, and the social implications of using food crops for fuel production. Some users mention the need for engine modifications to optimize performance with alcohol fuels, while others highlight the existence of flex-fuel vehicles designed to run on ethanol. The conversation also touches on the economic aspects of ethanol production and its impact on food prices.
