Proposed 5th edition of Worldwide Fuel Charter introduces new Category 5 for fuel efficiency and emission control

9 January 2013

The proposed new 5th edition of the Worldwide Fuel Charter (WWFC5), which is available for comment through 28 February, introduces a new Category 5, which the Committee adopted to distinguish markets with highly advanced requirements for fuel efficiency as well as for emission control. The proposed WWFC5 provides automaker and engine manufacturer proposed recommendations for the quality of market gasoline and diesel fuel.

For gasoline, Category 5 raises the minimum gasoline research octane number (RON) to 95. For diesel fuel, this category establishes a high quality hydrocarbon-only specification that takes advantage of the characteristics of certain advanced biofuels, including hydrotreated vegetable oil (HVO) and biomass-to-liquid (BTL), provided all other specifications are respected and the resulting blend meetes defined legislated terms.

Category 5 markets are seen, for example, as those with Category 4 emission standards that also require US 2017 light-duty fuel economy, US heavy-duty fuel economy, California LEV III or equivalent emissions control and fuel efficiency standards.

Other changes from the previous edition include a new test method for trace metals, an update gasoline velocity table and updated information relating to biofuels, including ethanol, biodiesel and other alternatives to petroleum-based fuels.

The revised Category 4 will allow biodiesel in diesel fuel at levels up to 5% by volume. The Charter now also references the E100 and B100 Guidelines published by the WWFC Committee in 2009.

The WWFC Committee will produce a Response to Comments and a final version of the WWFC5 after reviewing any comments received.

The World-Wide Fuel Charter Committee is made up of representatives of auto manufacturers from Europe (ACEA), the USA (AAM) and Japan (JAMA) and engine manufacturers (EMA), with associate members from most other countries where automobiles are manufactured, and with the support of OICA (Organisation Internationale des Constructeurs d’Automobiles / International Organization of Motor Vehicle Manufacturers).

The current 4th edition of the WWFC was published in September 2006.

Bio-fuels seems to perform much better (with far less emissions) than fossil fuels in Jets.

Why not give that application priority and accelerate the switch from ICEVs to Electrified ground vehicles to reduce consumption of fossil fuels?

That would lower USA's Oil imports, reduce harmful emissions and reduce USA's trade deficit at the same time.
