Biofuels are increasingly used as blending components for transport fuels. Biofuels possess much different chemical structures from conventional fuels, and can therefore interact with hydrocarbon fuels during engine combustion processes and consequently affect engine efficiency and emissions. This project aims to investigate the chemical interactions between representative compounds of biofuels (ethanol) and fossil fuels (n-heptane, iso-octane and toluene) during engine autoignition processes. The outcomes will fill a significant gap in our understanding for biofuel combustion chemistry, essential for building predictive combustion models, and will guide the best use of the precious Australian biofuel resources to reduce carbon dioxide emissions.

Natural gas direct injection in advanced engines and powertrains. Natural gas direct injection in advanced engines and powertrains. This project aims to quantify and understand how future, advanced passenger vehicles might perform when optimised for the direct injection (DI) of natural gas. Such production vehicles do not exist, largely because production DI systems for natural gas, spark ignition engines are not yet available. This project will examine both advanced conventional and hybrid vehi ....Natural gas direct injection in advanced engines and powertrains. Natural gas direct injection in advanced engines and powertrains. This project aims to quantify and understand how future, advanced passenger vehicles might perform when optimised for the direct injection (DI) of natural gas. Such production vehicles do not exist, largely because production DI systems for natural gas, spark ignition engines are not yet available. This project will examine both advanced conventional and hybrid vehicles using a suite of state-of-the-art experimental and numerical techniques. This project will quantify these vehicles’ environmental, technical and economic performance to determine whether DI natural gas, conventional and hybrid vehicles might reduce substantial greenhouse gas (GHG) emissions whilst avoiding any consumer penalty. This research could contribute to global GHG abatement.Read moreRead less
Development of low emissions compression-ignition engines via ethanol port-injection dual-fuelling. The project aims to develop a more efficient and more cost-effective way of utilising clean-burning ethanol fuel. Port-injection fuelling of ethanol as a separate fuel stream in compression-ignition engines will be studied fundamentally and combined with novel combustion strategies to overcome problems that occur at high ethanol substitution.
Flame-wall interactions in diesel engine environments. This project aims to advance the fundamental understanding of flame-wall interactions in diesel engines, which is currently very limited despite the wall's significant impact on combustion and pollutants. The aim is to perform the most comprehensive set of measurements to date in a high-pressure chamber and optically accessible engine, including planar imaging of key species and soot, and space-/time-resolved measurements of wall temperature ....Flame-wall interactions in diesel engine environments. This project aims to advance the fundamental understanding of flame-wall interactions in diesel engines, which is currently very limited despite the wall's significant impact on combustion and pollutants. The aim is to perform the most comprehensive set of measurements to date in a high-pressure chamber and optically accessible engine, including planar imaging of key species and soot, and space-/time-resolved measurements of wall temperature. These are intended to be complemented by the first transported probability density function modelling of a diesel spray flame that includes soot, radiation and wall heat transfer. The expected outcomes will greatly advance understanding of flame-wall interactions, thus contributing to the development of cleaner and more efficient engines.Read moreRead less
Accelerating clean automotive innovation: fundamental insights into alternative fuel combustion. To achieve the maximum efficiency from alternatively fuelled engines, better understanding and predictive models are needed for the major limiting factor in spark-ignition engine efficiency: knock. The project will address this gap, thereby accelerating development of better engines and strengthening national capacity in clean engine technology.
Low emission road transportation: harnessing the potential of alternative fuels and advanced vehicle technologies through online optimisation. This project will develop fundamental mathematical theory and use it to enable the best possible CO2 reduction capability in road vehicles. The cost of different technologies and fuels will then be compared to determine the most cost effective approaches to reduce road transport emissions.
