Hey guys,

I'm a senior engineering student working on modeling internal combustion engines and temperature regulation through the use of advanced technology.

Being a Nitro guy, I suggested to my professor that we use an RC engine as a simple model, and he loved the idea!

The first step of my research is trying to find the heat Energy released by the engine, but I need some information that is not found in Thermodynamic books. What is the chemical composition of our nitro fuels (say 30%)?

For those of you who may be fellow mechanical engineers, any idea where I can find the heating value for RC fuels? I have never seen a "spec sheet" for our fuels listed on manufacturer's websites.

Any help is highly appreciated!

Fuel is easy, it's just three main components.

Some percentage of nitromethane, usually 20 to 30%

7-12% oil. Usually a blend of castor oil and synthetic.

The rest is methanol. That's pretty much it.

Some brands will add small amounts of anti-foam agents, corrosion inhibitors, etc. but usually it's just the three mentioned earlier.

Contact Byrons. From what I have seen on their website, they are one of the only manufacturers that give alot of information regarding their fuels. They may give you some more information since you are doing a project.

I did find some spec sheets on the Byrons website. I will contact them in regards to the blend's Heating Value, which will help me in calculating the amount of energy released in the combustion process (most of it being released as heat, of course). Thanks!
