This project aims to develop universal and programmable engine management systems for gasoline direct-injection engines with lean-burn technology and optional natural gas port-injection. The new engine management system will enable higher fuel efficiency than its predecessors and the increased use of nationally-produced natural gas. The project aims to overcome three main problems that limit efficiency improvement of direct-injection engines, namely: misfiring, unstable combustion, and soot emission. How these issues are impacted by additional natural gas port-injection will also be explored. This project aims to accomplish this by combining fundamental in-cylinder optical measurements and detailed modelling.Read moreRead less
In-cylinder soot sampling and morphology analysis in an optically-accessible diesel engine. Black soot emissions from diesel engines are associated with respiratory illness, cancer, and heart attacks. This project aims to reduce diesel soot emissions by clarifying the nature of the structure and size of soot particles that are sampled from both the engine cylinder and the tailpipe.

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.
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.

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
