What does N14 mean?
N14 is a designation used in vehicle emissions regulations set forth by the International Organization for Standardization (ISO). The designation refers to a type of hydrogen-rich (hydrocarbon) gaseous fuel intended to be used in non-road applications, such as forklifts, construction equipment, and agricultural equipment.
N14 fuel contains a minimum of 14% hydrogen content by volume, as well as a maximum of 75% carbon dioxide (CO2) by volume. The fuel may also contain a maximum of 5% methane (CH4), with higher percentages of other hydrocarbons, such as propane and butane, being allowed.
The purpose of the regulation is to help reduce harmful pollutants from non-road machinery, as hydrocarbons like those found in N14 fuel burn more efficiently than traditional diesel, resulting in fewer emissions.
