Currently biofuel production methods focus on the production and isolation of individual components. However, mixtures of products tend to be formed and the isolation is an expense that could be eliminated if the blend of products could be directly utilised in fuel blends and current engine technologies. The concept of tailored fuel design considers fuel properties according to the molecular structures available to the evolving reaction mixture to give the best combustion behaviour for a certain application. This project aims to determine how a blend of biofuel components as an increasing percentage of gasoline and diesel will affect the performance of these fuels. My work should also generate data for the optimization of biofuel/conventional fuel formulations for drop-in deployment with clean and efficient utilisation, the minimisation of greenhouse gas (GHG) and pollutant emissions, and the associated production costs of these fuels.

The effects of the biofuel blend composition on the following parameters would be measured or determined:

Ignition delay - to determine if the blend changes the combustion characteristics of the fuel, which would be measured using the research engines in the engine testing facilities.
Emissions of NOx, PM, CO2 and other GHGs would be measured using the engine testing facilities and the exhaust gases analysis equipment.
The engine performance and efficiency will be measured using the research engines as the change in the fuel chemistry will affect how the engine performs.
Derived cetane and octane numbers as these give an indication of the fuel's performance.

The project would use a combination of experimental engine testing and computational kinetic modelling of the fuel's behaviour. The modelling would be used to both predict and validate the engine studies, with the hope that it could determine what blends would be best to run engine tests on. The aim would be to combine these to be able to produce a matrix of how varying the amount of a specific fuel component would affect the four key characteristics mentioned above. The matrix would then enable the optimum fuel blend to be produced for its given application.
