    Buy an Efficient Car

    With the emergence of peak oil and climate change as hot issues, car makers have beenfocusing their engineers on fuel efficiency, aerodynamics and hybrid technology. So

    when youre next in the market for a new set of wheels consider buying an efficient car

    Cars are the primary mode of transport in Australia with most households having at leastone. he current generation of cars emit greenhouse gases, which contribute to climatechange. !or every litre of petrol used in a motor vehicle, ".# kilograms of carbon dioxide$C%"& is released from the exhaust.

    he new breed of efficient cars and hybrids are increasing fuel efficiency by significantmargins and with electric cars about to emerge onto the market in the next few years, wewill soon have cars with 'ero net carbon emissions.

    As one of the ma(or investments for most families, car efficiency also means lowerrunning costs, better insurance rates and even green loans.

    How to do it now!

    he efficiency of the vehicle $design, engine, weight, etc.& determines the fuelconsumption and the amount of greenhouse gases and air born pollution released perkilometre, so there are plenty of factors to consider to reduce the emissions you create.

    Buying a new efficient car

    !uel efficient cars have the following benefits)

    hey produce fewer C%" emissions, lowering their impact on the environment

    and contribution to climate change. hey consume less fuel and are therefore less expensive to run, year in year out.

    With peak oil, carbon taxes, and climate change concerns pushing the price offuel up, the savings derived from increased fuel efficiency will only increase.

    hey highlight and focus the economy and community on the value of our

    efficient use of energy.

    As the following table demonstrates, an efficient car reduces both your annual C%"

    emissions and the amount of money you pump into your car at the petrol bowser.

    he problem with all alternative fuels is that the manufacture of fuels re=uires energy,distribution with a manufacturing infrastructure that consume energy, often derived fromburning fossil fuels. Bo alternative fuel is ideal. See Switch to Hiofuels

    "ydrogen Eltimately cars might burn hydrogen in fuel cells, but despite working

    prototypes, a hydrogen economy is a distant fantasy. here are many problems to besolved before hydrogen can replace fossil fuels as a portable energy source. he biggestproblem is that producing hydrogen re=uires a large amount of energy. ?n Canada, thereare opportunities to dam rivers and produce electricity with falling water, a non polluting,renewable energy resource. A more problematic energy source would be be nuclearreactors that FburnF uranium or plutonium. *ven if new non4polluting energy sources aredeveloped, hydrogen storage and distribution re=uires a new, very expensiveinfrastructure that could replace gasoline and diesel fuels.

    O. What is a catalystD

    A. A catalyst helps substances react together but remains unchanged in the process. ?n anautomobile catalytic converter, the catalyst helps the pollutants $unburned hydrocarbons,carbon monoxide, nitrogen oxides and volatile organic fraction of particulates& react witheach other and other components of the exhaust gas to form non4toxic compounds $water,

    carbon dioxide and nitrogen&.

    O. o catalytic converters spoil the performance and driveability of cars and increase fuelconsumptionD

    A. 0odern catalytic converters do not reduce vehicle performance significantly undermost driving conditions because they are designed with low backpressure as an integralpart of the exhaust system. With the advances incorporated in todays engines, theyperform significantly better both in terms of power and fuel economy than their pre4catalyst ancestors.

    O. ?s it true that catalytic converters don@t work on a short (ourney such as the FschoolrunF or a visit to the shopsD

    A. Bo. While catalytic converters do need a moderately hot exhaust to start working, it isa myth that catalytic converters do not work on short (ourneys. *mission control systemsbecome operational as soon as the engine conditions permit. ?n fact modern catalyticconverters fitted to passenger cars start working in a few seconds and iesel +articulate!ilters remove particulates under all conditions.

    O. What is the effect of sulfur4free fuel on exhaust emissionsD

    A. *xhaust emissions will be lower 4 particularly from catalyst4e=uipped cars. Sulfur inpetrol and diesel fuel has a ma(or negative impact on catalyst performance, especially forB%x catalysts and adsorbers. he effect of sulfur on catalyst performance becomes more

    critical as lower tailpipe emissions are targeted for the very low emission levels nowre=uired. Sulfur strongly competes against pollutants for FspaceF on the catalyst surfacelimiting the efficiency of catalyst systems to convert pollutants at any sulfurconcentration 4 so the lower the sulfur levels in fuels the better the catalyst performancethat can be obtained. he conversion of sulfur to a sulphate aerosol can cause netincreases in diesel particulate emission.

    O. What are the differences in toxic emissions from diesel and petrol enginesD

    A. Hecause maximum power production from diesel engines is fuel and not air limited itis still the only engine that is Flean burnF across the full power3speed range. his brings

    A. he best way is to use a particulate filter. hese systems consist of a filter positionedin the exhaust line and designed to collect solid and li=uid particulate matter $+0&emissions while allowing the exhaust gases to pass through the system. ?ncreasingnumbers of diesel cars, trucks and buses are now being fitted with iesel +articulate!ilters $+!&.

    A. Bo, based on engine technology and engine management, different filter technologiesmay be used to meet the prescribed emission standards.

    ?t is possible with advanced filter technology $wall4flow filters& to almost completelyeliminate the carbon particulates, including fine particulates of less than nanometres$nm& diameter with an efficiency of N;-J in mass and N;;J in number. he removal ofultra4fine particles is very important since health experts believe that they are carrieddeep into the lungs and are thought to be the most dangerous si'e of +0.+artial4flow filters operate with the bypass flow principle. he overall filtration efficiencyof these partial4flow filters is #46J in mass depending on application and operatingconditions.

    can be done through passive regeneration $continuous oxidation of particulates by B%"&,the use of a !HC which lowers the soot burning temperature, or, active engine controlstrategies periodically increasing the exhaust temperature. Any residual ash can becleaned during maintenance if re=uested by the car manufacturer but most passenger carsystems are now designed to last for the lifetime of the vehicle without maintenance.

    by current regulations.

    O. Catalytic converters produce C%". ?s this adding to the greenhouse effectD

    A. All the carbon contained in fossil fuels is ultimately converted to C%" in theatmosphere. Hy accelerating that conversion, and removing other dangerous pollutants inthe process, catalytic converters do not increase overall C%" levels. he only way toreduce C%" emissions is to burn less fossil fuel.

    O. What is retrofitD

    A. ypically, retrofit involves the addition of an emissions control device to removeemissions from an existing vehicle.

Someexamples of emissions control devices used for diesel retrofit include diesel oxidationcatalysts, diesel particulate filters and selective catalytic reduction systems. 0oreinformation on eavy4duty iesel retrofit in *urope can be found here.
