This project aims to clarify the mechanism of power losses in magnetic cores used in the petrol-electric hybrid cars by investigating the relationship between the core losses and magnetic correlation lengths in iron alloys. This project expects to generate new knowledge on the effect of magneto-mechanical interaction on the anomalous core loss in iron based alloys. The intended outcomes include an experimental confirmation of the random anisotropy model, a major theoretical model in nanostructured materials and identification of ideal magnetic domain configurations for lower power losses. These intended outcomes should bring great benefits to the development of low-carbon vehicle technologies for sustainable motorisation in Australia.Read moreRead less

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

Nanostructured soft magnetic alloys for low-carbon cars. The aim of this project is to prepare iron-based magnetic nanostructures that exhibit a magnetic induction of 1.9 tesla and core losses lower than those of iron-silicon steels, which would deliver smaller and efficient magnetic cores for petrol-electric hybrid cars. Preliminary results from the research team show that iron-metalloid alloys with an iron content of 87 per cent meet this magnetic induction with room for further improvement of ....Nanostructured soft magnetic alloys for low-carbon cars. The aim of this project is to prepare iron-based magnetic nanostructures that exhibit a magnetic induction of 1.9 tesla and core losses lower than those of iron-silicon steels, which would deliver smaller and efficient magnetic cores for petrol-electric hybrid cars. Preliminary results from the research team show that iron-metalloid alloys with an iron content of 87 per cent meet this magnetic induction with room for further improvement of magnetic softness. The project aims to systematically investigate the effect of metalloid and micro-alloying elements on the nano-crystallisation behaviour of the precursor amorphous alloys in order to identify the alloy composition and processing conditions for preparing magnetically soft nanostructures.Read moreRead less

This project aims to develop alternative hybrid electric and pure electric vehicle technologies for the Australian commercial vehicle sector. Worldwide concern about greenhouse gases and stringent vehicle fuel consumption have changed vehicle driveline systems, and created demand for hybrid and electric automotive technologies. This project will examine different powertrain configurations for commercial vehicles, and use numerical simulations to evaluate vehicle fuel economy, life cycle emissions and life cycle costs and demonstrate the benefits of these alternatives. These vehicle technologies have the potential to reduce fuel in this sector by up to 50%, and reduce vehicle emissions and operational costs across the commercial transportation sector.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.

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
