how does petrol and ethanol blended petrol differ in terms of engine performance?

Question

how is the procedure of blending ethanol with petrol?

Answer 1

It is no recommendable, blend petrol with ethanol.
The best is gasoline with ethanol.

Answer 2

The addition of ethanol in gasoline fuel in small amounts (10%-ish) will boost the octane level of the gasoline while doing little to nothing to the efficiency. It is also proported to help the gasoline burn a little cleaner and reduce emissions.
The lastest thing is to use high percentage ethanol (85%). The fuel acts a little differently, so the car you use it in need to be capable of handling the different fuel charge. Generally, these high ethanol content fuels burn cleaner then the normal gasoline, but the heating value of the mix is lower, so you don't get as much energy out of the fuel (use more fuel). The jury is out as to whether the cost vs. fuel efficiency will work out favorably. Also some questions about availability of ethanol production and distributio

Answer 4

First you have to have what you need.

In most cases with slight adjustment you can use other fuels.

Jury is not out on Ethanol, you are trading fuel effeciency for cleaner burn. But since you will use more fuel the total polution figure are not yet available. Need research. In USA lots of state already require the use of up to 15% minimum ethile alcahol.

Blending is a simple mixing process, but both gas and the ethile alcohol are highly flameble, luckily it is not economical for a person to blend the two on its own.

Production is another thing, both are very eleborate process.

Answer 5

Diesel is a bit more expensive than petrol in the uk. Diesel cars are a bit more expensive petrol cars. diesel cars have no ht leads , no spark plugs , no coil , or electronic timing. Diesel cars are a bit more slugish at pulling away , reving up etc , but once going deisels out perform petrol at say accelerating from 50 mph to 80 mph. Diesel engines will do more mileage in a lifetime that petrol. Road tax and emmisions may be different depending on make of car cc engine etc. In general go for diesel if you drive more on motorways , long distance , petrol if more around town.

Answer 6

arun, as far as a city-based driver is concerned, the difference would be negligible.

do note that ethanol mix fuel is less polluting, and you'll be doing your bit to conserve the planet's diminishing resources...

however, if you don't give 2 hoots about the ecology, then you'll sorely miss petrol!

an ethanol mix fuel will decrease engine peak-end performance, and acceleration time will take longer. that's why ethanol fuel is recommended for city-based situations.

in a race-situation, it would be considered a very poor fuel.

however, one must admit that ethanol mix fuel has a much cleaner burn, and the reduced emission means you have lower carbon deposits in your engine, and fewer service problems...

so choose your fuel wisely!

enjoy...!

Answer 7

ethanol can be corrosive to fuel systems. Not generally a problem with proper materials selection.
