NREL Updates Cetane Data Used for Development of Energy Efficient Fuels and Engines

10.09.2014

The Energy Department’s National Renewable Energy Laboratory (NREL) has released a long-anticipated update to the source-of-record for cetane number data. This information is vital to the development of new, energy-efficient, low-carbon fuels and compatible engines.

Researchers, as well as members of the engine, vehicle, and fuel industries, rely on these numbers to target compounds for development of new fuels capable of greater energy efficiency, cleaner emissions, and maximum performance in diesel engines.

A cetane number is a relative ranking of fuels based on the amount of time between fuel injection and ignition (ignition delay) in a diesel engine. A minimum cetane number is specified in the ASTM standard that defines the quality of diesel fuel sold in the United States.

The recently published Compendium of Experimental Cetane Numbers compiles cetane number data from 62 sources for readers to use in selecting potential compounds and formulas for development of models, tools, and fuels.

In addition to updating information, the new edition provides additional measurements on a larger number of compounds, along with assessment of data quality.

The updated report includes all available single-compound cetane number data found in the scientific literature published prior to March 2014, including:

  • Information on 389 pure compounds

  • 584 measurements, including more than 250 new measurements

  • Expanded discussion of the accuracy and precision of the methods most commonly used for determining cetane numbers

  • Extensive annotation allowing readers to judge the relative reliability of individual results.

“The original report has been cited more than 130 times,” NREL Principal Engineer Robert McCormick said. “We expect that the new edition will continue be used extensively to develop models, target compounds for new fuels, and tools to help predict cetane numbers in the future.”

NREL is the U.S. Department of Energy's primary national laboratory for renewable energy and energy efficiency research and development. NREL is operated for the Energy Department by The Alliance for Sustainable Energy, LLC.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
