Cleaner transport through engine ‘neurosurgery’ and re-cycled cooking oil

27.07.2005


The next generation of motor vehicles could be powered by engines that are cleaner, greener and smarter, thanks to research at two universities in South West England.



Engineers at the University of Bath are carrying our research described as being like ‘neurosurgery on diesel engines’ to find ways of making them even more efficient than their petrol-driven equivalents.

Meanwhile, researchers at the University of the West of England are experimenting with the production of fuel made from a mixture of recycled vegetable oil and glycerine that could one day be used in the University’s own fleet of vehicles.


Both research projects are highlighted in a new video news release produced by Research TV as part of the South West Regional Development Agency’s Inspire Fund.

Diesel engine’s reputation as a dirty, messy fuel is a thing of the past, say researchers, with current engines recording just 50 per cent of the emissions that engines produced only seven years ago.

“The miles per gallon that you can actually get from a diesel engine now, while still retaining good power and still retaining good drivability which is what the public wants, have put it in a position where it can compete with the petrol engine on many fronts,” said Professor Gary Hawley from the Powertrain and Vehicle Research Unit at the University of Bath.

“Diesel engines used to be thought of as dirty and smelly and particularly loud but that’s not so any more, they’re actually very refined complex machines.”

His research is looking at the heat flow inside a diesel engine and trying to find ways of reducing the amount of energy wasted; for every kilowatt of power currently produced by modern diesel engines, some 2 kilowatts are thrown away.

By tracking the intimate detail of heat flow in the engine and the variation of heat flux in the cylinders, the researchers hope to improve modelling accuracy which, in turn will help the design of more efficient engines.

At the neighbouring University of the West of England, researchers have been experimenting with the production of biodiesel fuel from recycled vegetable oil recovered from the University canteen.

The research is part of a wider study into biofuels that could also benefit the rural economy. Dr Stuart Shales, senior lecturer in environmental biotechnology, said, “Biofuels may well have a major role to play in the future to help ease the pressure on world crude oil supplies, and contribute to the 37.6 million tonnes of motor fuel used every year in the UK.

“We are experimenting with fuels produced from recycled vegetable oil, and are equally interested in processing fuel from plant sources such as rapeseed.

“There is only a finite amount of recycled oil we can get hold of, whereas by using rapeseed oil, for example, we could also benefit the rural economy, by bringing into use the extensive agricultural land that is currently in set-aside, for growing crops for fuel.”

The film shows how researchers treat recycled oil to reduce its viscosity so that it does not cause damage in diesel engines. It burns in a similar way to fossil fuels and releases a similar amount of energy.

Other possible biofuels under investigation in the UWE project are : bioethanol (petrol substitute); biodiesel (diesel substitute); hydrogen (e.g. from microalgae); biogas (methane) and biomass crops.

The project aims to find ways to reduce production and processing costs, encourage organic horticulture of oilseed crops and develop on-farm processing of oilseed and production of biodiesel.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
