The aim of this project is to experimentally design novel biosynthetic fuels and investigate their stability, combustion, and emission characteristics and their effects on regulated, unregulated and GHG emissions in order to improve the engine performance and achieve complex reduction in exhaust gas emissions. This research will make an important contribution towards the development of advanced low-carbon fuels and engines.
In this project, the design properties, property targets, and acceptable tolerances on meeting the required fuel physical and chemical properties will be established. The main design properties selected for this study will be fuel composition, ignition quality, volatility, and density. These are selected in an attempt to match the engine in-cylinder vaporization, mixing, and combustion processes of the target fuel, with the understanding that there is no guarantee that matching these design properties will produce identical engine emissions or performance. Other design properties such as surrogate fuel cost, mean molecular weight, C/H ratio, lower heating value, and threshold sooting index will also be analysed.
13C (carbon) and 1H (proton) nuclear magnetic resonance (NMR) spectroscopy and GCxGC-FID will be used to quantify the compositional characteristics of each target biosynthetic fuels. The per-atom data are expected to correlate better with engine emissions characteristics (e.g., sooting propensity) than the per-molecule data because of better resolution of the carbon bond types within each molecule.
The description of the biosynthetic fuel physical and chemical properties will be presented for different fuel concentrations, temperature, as well as the effect of additives on fuel miscibility and stability. The experiments will be conducted in a fully instrumented engine test cell with research single cylinder engine, multicylinder commercial engine and FTIR gas analyser to analyse the engine performance and exhaust gas emissions.
