What is the compression ratio for alcohol?
It’s not uncommon to see alcohol engines using as high as 13:1 or 14:1 compression rations with little fuel-related problems. Of course, high compression engines have other mechanical issues that aren’t related to fuel.
What is the best compression ratio for methanol?
Approximate compression ratios recommended for use with Nitro-methane / Methanol fuel mixes. It must be remembered that for all practical purposes 14 to 1 should be considered the maximum usable compression ratio in modern short stroke automotive type engines.
Can cars run on pure alcohol?
Practically any car could run on high-potency hooch, though the level of performance would vary. Most automobiles made prior to 2000 aren’t equipped to handle alcohol long-term, and fueling with ethanol can lead to leaks, rust, and corrosion.
Which alcohol is best for race cars?
Most race car drivers prefer fuel that is methanol- or ethanol-based, and the reason is simple, really. Overall, alcohol-based fuel has a high octane rating which increases fuel efficiency. Methanol burns cleaner and cooler, is less flammable, and less expensive than gasoline.
What is alcohol race fuel?
Alcohols like methyl alcohol (methanol) and ethyl alcohol (ethanol) are often used in race fuels. Methanol is commonly used “straight” – that’s why it’s called racing alcohol by many. Ethanol can also be used straight, and some racers do, but it’s more common to hear about E85, a blend of about 85% ethanol.
How do you make an engine run on alcohol?
To run effectively, an alcohol motor needs to burn approximately twice as much fuel as a gasoline motor.
How much compression can you run on methanol?
it can run with as little as 5 to 1 compression ratio…
Can I put 10 percent ethanol in my car?
All gasoline engine vehicles can use E10. Currently, only flex-fuel and light-duty vehicles with a model year of 2001 or newer are approved by the EPA to use E15. Flex-fuel vehicles can use any ethanol-gasoline blends up to E85. The energy content of ethanol is about 33% less than pure gasoline.
Is 10% ethanol bad for cars?
You might notice a slight improvement in fuel economy – ethanol has less energy per gallon, so ethanol-gasoline has about 4% less energy than straight gasoline. You have to ask yourself is it worth it to maybe get 1 MPG more than E85 considering that it costs more. Maybe 70 cents a gallon more.
