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

This project aims to provide the first fundamental-level understanding of the processes of ignition, combustion, and pollutant formation relevant to a new, highly efficient combustion mode known as gasoline compression ignition (GCI). This project aims to provide information using a unique combination of direct numerical simulations, advanced transported probability density function modelling and a suite of laser measurements in a high-pressure combustion chamber. GCI engines have significant potential to improve fuel economy and reduce emissions harmful to health and the environment. The outcomes from this project will lead to accelerated development of the GCI engine, and more optimal GCI solutions to be found.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.

Two-stage ignition and flame stabilisation in engine-relevant conditions. This project aims to reveal the mechanisms of ignition and flame stabilisation in the temperature and pressure conditions that exist in diesel engines, understanding of which is currently very limited despite their significant bearing on pollutants and fuel efficiency.

This project aims to reveal the mechanisms of ignition and flame stabilisation in the temperature and pressure conditions that exist in diesel engines, understanding of which is currently very limited despite their significant bearing on pollutants and fuel efficiency. Using massively parallel supercomputing resources, the most detailed, direct numerical simulations of ignition and flame stabilisation to date will be performed - they will be three-dimensional and use a detailed chemistry model able to account for low-temperature kinetics and two-stage ignition. Analysis of these data aims to reveal how ignition and flame stabilisation depends on key turbulence and chemical kinetic parameters, thus contributing to developing low-emissions diesel engines.Read moreRead less
