Point of combustible diesel makes easier the ignition is good. The combustion. However, there are no little carbon black smoke. (Particulate) and sulfur dioxide over the environment A constant viscosity
The flammable than diesel The explosion did well Complete combustion So little smokeless carbon black (Particulate) and sulfur dioxide worsen the environment. Constant viscosity
Fire point than diesel fuel. The ignition, combustion, good complete carbon monoxide, so less "no black smoke. (Particulate)), and sulfur dioxide aggravate environment viscosity constant.
