<< Regardless of how the fuel is ignited, diesel contains roughly 30% more BTU's than gasoline.>>
Dave - According to my reference books that is not accurate. According to "Internal Combustion Engines" a mechanical engineering text book by Obert - Motor gasoline - 20,300 Btu/lb or 124,300 Btu/gal Diesel No 2 - 19,700 Btu/lb or 137,000 Btu/gal Diesel fuel contains about 10% more chemical energy than gasoline. Diesel No 1 values are similar. The hottest of any fuel oil is "No 5 light" at 151,000 Btu/gal. But No 5 light is very dense and viscous. Ned Kleinhenz
