What is the Difference Between Gasoline and Diesel?
1 Answers
The differences between gasoline and diesel are as follows: 1. Volatility differs: Diesel is difficult to volatilize; gasoline has strong volatility. 2. Reaction with air differs: The mixture of diesel and air is uneven, with local oxygen deficiency or local oxygen-rich conditions; gasoline easily mixes with air and the mixture is not easily separated. 3. Chemical differences: Diesel contains more carbon atoms, ranging from 12 to 15; gasoline contains fewer carbon atoms, ranging from 8 to 10. 4. Combustion methods differ: Due to its higher carbon content, diesel requires more air and is not easily ignited by spark plugs, so a compression ratio of 15 to 18 times is needed to compress the diesel-air mixture for combustion; gasoline molecules are smaller and more active with a lower ignition point, so an ideal state is achieved when the gasoline engine mixes air in an ideal ratio and compresses it to around 10 before ignition by the spark plug.
