school help: well i’m in high school and i’m in a gifted program where i go to college for math and science classes. - Help.com

…does that kind of gas work on any kind of motor…like say a lawn mower? Could you test it that way…?? Do a bunch of trial runs…I mean maybe it’s not the same thing…at the very least you can see which works better for a lawn mower :D

-PS This may be one have the stupidest thing I’ve ever said, unless lawn mowers really can run on biofuel :P

Yay!! Well I hope it works out for ya!!

get a modern diesel engine. That should work splendidly.

you could use a bomb calorimeter which measures the amount of energy given off by the complete combustion of the biofuel

lol does biofuel go through complete combustion? anyway i say light em up an see how much/fast it burns haha

You could always show the differance in the way they are made, and the amount of exaust they spew, but i’m with whoever said use a lawnmower, that was a good idea.

Enter “Biofuel comparisons” or “Biofuel testing” in your browser bar and reaserch the test results of other biofuel projects and see if you can pick up on a way to make your demonstration. record information on comparisons between fuels. If you can not afford to use an actual motor, you can make charts and paragraphs, photos, and references to make your presentation work. If you understand the theory behind it, you should be able to make your point in class.

You also have to remember that most lawn mowers are 2 cycle engines that use premix! This means that the biofuel may react differently in a 2 stroke engine than in a car where the oil is separate.
