Students can actually see which fuel produces more torque! Which burns hotter, propane or alcohol. Information like this can be graphed, and compared on a computer, then saved or printed. The software package, is a powerful training aid for any student learning alternate fuels. Graph multiple runs of the, using alternate fuels (propane, methanol, ethanol, etc.), showing the properties of each. Study high performance engines, as the engine allows for different compression ratios and timing to be selected, then Horsepower and Torque to be viewed on screen.
