Different types of fuel for a metro????

Just pondering a question and need some feed back.

Can these fuels be used in a metros engine, and if not please state why not and what additives can be utilized in order for the fuel to work. I'm working under the assumption that a full 10.5 gallons of said fuel will be in the gas tank.


1. Unleaded gasoline

2. E0 gasoline

3. diesel fuel

4. Kerosene

5. E85 gasoline

6. Rubbing Alcohol

7. Moonshine

8. Jack Daniels whiskey

9. JP4

Thanks for your input.

My favorite 3 fuels are mid grade pump gas, lead acid batteries, and lithium ion phosphate batteries. I make it a point to avoid jp4, jp5, kerosene, and any other form of diesel.

No, I did not. I don't want to rebuild my engine so I could use that type of fuel. I just want to pour and play. B-)

Only the three that say gasoline in their name, and at that E85 is not a good idea.

I will trade you two gals. of gasoline for every gal of Jack Daniels you don't burn and give to me. ^o)

Thanks for your input Woodie.

Now I would like to know why the other non-gasoline fuels would not work. Why wouldn't moonshine or diesel work in an internal combustion engine. They ignite when a flame is put on them, so why not in the combustion chamber of a gasoline engine?

I really want to get down to the physics of this, so if you smart rocket scientists care to jump in, I would appreciate your info.

Thanks

They could conceivably work, but not well. They're different chemically, and require different conditions to burn well. Your engine is set up with 9.5/1 compression (I think, might be 9/1) and 14.7/1 air to fuel ratio. That is what gasoline requires. These factors and many others having to do with combustion chamber design and intake manifold design are carefully chosen and balanced with consideration for performance, emissions, driveability, and longevity.

Because alcohol has oxygen in it, the proper air/fuel ratio is very much lower, methanol is 6.4/1, ethanol is 9/1. It would also like a little more compression. This is one of the reasons why alcohol does not make sense as a fuel for cars, why pay for liquid oxygen when air is free?

Diesel fuel (Home heating oil, JP4, kerosine) wants an incredibly high compression ratio, sometimes 20/1, but will work with almost any air/fuel ratio. Diesels often run unthrottled (air intake is wide open at all times, and throttle control is performed by changing the amount of fuel ONLY. Therefore at idle, the engine is running on mostly air, with a crazy high air/fuel ratio. When you stomp on it the amount of fuel is increased drastically and the air/ fuel ratio drops down to what would be incredibly rich for a gas engine, that's why diesels get sooty when being flogged hard.

This is a quick and simplistic answer, I'm sure someone with a better understanding of the subject could explain it better, but that's the gist of it.

Thanks again Woodie..

Are there any additives which would make the compression ratio come DOWN on diesel, jp4? Sta-bil, MMO???

The compression ratio of an internal-combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its largest capacity to its smallest capacity. It is a fundamental specification for many common combustion engines.

5. E85 gasoline
7. Moonshine
These two are very similar except moonshine is basically E98-E100 depending on how many times it's been distilled.
