Emissions Properties of NGVs
                               Lower in:
                                   Carbon monoxide (CO)
                                   Hydrocarbons (HC)
                                   Nitrogen oxides (NOX)
                                   Greenhouse gas
                                       emissions (CO2)

                               Zero:
                                   Particulates
                                   Evaporative emissions

How Natural Gas Compares to    Source and Physical State
Gasoline and Diesel            Ignition and Flammability
                               Weight and Energy

                                  Comparison
                               Octane and Cetane Rating
                               Transportation and Storage

What Is Octane?                Rating for the ability to resist
What Is Cetane?                   detonation
                                    The higher the number,
                                        the higher the
                                        temperature required to
                                        ignite the fuel

                               Rating of the speed at which
                                  fuel begins to combust
                                    The higher the number,
                                        the faster the ignition
                                        begins
