Surrogate fuels designed for specific combustion settings enable combustion simulations that leverage chemical kinetic mechanisms. A unique computational device, the Fuel Design Tool (FDT) has been developed and tested to formulate surrogates for various transportation fuels.
- Surrogate fuels for several transportation fuels are formulated using the FDT and have been successfully evaluated in different combustion settings.
- FDT is also useful in the design of fuels for explicit experimental and modelling conditions.
- The FDT has been implemented on the CloudFlame portal to allow combustion researchers to design fuels and formulate surrogate fuels specific to their requirements.
- Detailed exploration of surrogate fuel formulations also led to enhanced understanding of effects of physical properties on combustion parameters.

The AramcoMech 2.0 builds upon AramcoMech1.3 and has been developed to characterize the kinetic and thermochemical properties of a large number of C1–C4-based hydrocarbon and oxygenated fuels over a wide range of experimental conditions. It was developed by the Combustion Chemistry Centre at NUI Galway and funded by Saudi Aramco.
AramcoMech2.0 has been developed hierarchically from the bottom up, starting with a H2/O2 sub-mechanism and followed by a C1 sub-mechanism; it has grown to include larger carbon species such as ethane, ethylene, acetylene, allene, propyne, propene, n-butane, isobutane, isobutene, 1-butene and 2-butene, and oxygenated species, including formaldehyde, acetaldehyde, methanol, ethanol, and dimethyl ether.
This mechanism has been validated against a large array of experimental measurements including data from shock tubes, rapid compression machines, flames, jet-stirred and plug-flow reactors.
The papers listed below refer to the work from which the mechanism is derived.

The gasoline surrogate mechanism includes detailed chemistry for multi-component gasoline/naphtha fuel surrogates. Several species, relevant to the formulation of gasoline surrogates, are present in this mechanism, which has been validated against a large database of shock tube and rapid compression machine ignition delay times, as well as speciation data from flow reactors and premixed laminar flame speeds. The mechanism is validated for the following species:
- iso-octane (2,2,4-trimethylpentane)
Following are the available versions of the mechanism, along with the thermo-database and transport files.
