Variable Geometry Cooling Intakes for Passenger Vehicles. Cars reject engine heat via air forced through the grille, radiator and engine bay. The associated "cooling drag" increases total aerodynamic drag by 10-15% hence increasing fuel consumption. The highest heat load that needs to be rejected by the engine determines the quantity of cooling air, resulting in systems that are over designed for typical driving. This research provides a strategy of adjusting the cooling airflow to match the ....Variable Geometry Cooling Intakes for Passenger Vehicles. Cars reject engine heat via air forced through the grille, radiator and engine bay. The associated "cooling drag" increases total aerodynamic drag by 10-15% hence increasing fuel consumption. The highest heat load that needs to be rejected by the engine determines the quantity of cooling air, resulting in systems that are over designed for typical driving. This research provides a strategy of adjusting the cooling airflow to match the engine requirements (via variable geometry intakes that can be under the control of the engine management computer) offering substantial reductions in fuel consumption and emissions.Read moreRead less

Increasing the operational lifetime and optimising the design of crankcase oil-mist filters. Australia is one of the largest (per capita) users worldwide of heavy diesel engines, within sectors such as transport, mining, construction, shipping and power generation (usage of many of the above is concentrated in regional communities e.g. mining).

Australia is one of the largest (per capita) users worldwide of heavy diesel engines, within sectors such as transport, mining, construction, shipping and power generation (usage of many of the above is concentrated in regional communities e.g. mining). This work will minimise emissions from such industries, as well as reduce lubricant oil usage - thereby maximising waste oil recovery and reuse (approx 5500 tonnes p.a.). Oil mists can be regarded as volatile organic compounds (VOCs) for the purposes of CO2 equivalent emissions, so therefore, the efficient capture of oil mists will reduce carbon emissions from the above industries in Australia.Read moreRead less
The development of active third-generation heavy vehicle aerodynamic drag reducing devices to reduce future transport emissions. The potential for emission reductions through aerodynamic improvements is particularly apparent in long haul heavy vehicle transport.

The potential for emission reductions through aerodynamic improvements is particularly apparent in long haul heavy vehicle transport. By developing active devices to be fitted to the heavy vehicle trailer of the future this work offers drag reduction potential from current levels of up to 40 per cent. If widely implemented these devices could play a major part in the transport sector meeting medium term emissions targets. If successful not only will the project develop unique components, it will support heavy vehicle research and development that is so important to maintaining a strong manufacturing presence in Australia, especially in regional centres, such as Ballarat where Maxitrans has major headquarters.

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
