Run­ning on fresh air

Motor Equipment News - - NEWS -

In an at­tempt to cut fuel con­sump­tion to as low as 2L/100km, Peu­geot has turned away from elec­tric hy­brid power plants and has moved to air power.

Its HY­brid Air tech­nol­ogy is a key step to­wards this ob­jec­tive, and Peu­geot is pre­sent­ing the con­cept at the Geneva Mo­tor Show this month in its 2008 cross­over.

The new drive train fol­lows on ground-break­ing work over the past two decades by French­man Guy Ne­gre and his MDI com­pany in at­tempt­ing to bring a pure air car, and later a petrol-air hy­brid, to the mar­ket.

The air tech­nol­ogy, uses en­ergy re­cov­ered dur­ing brak­ing and de­cel­er­a­tion, much like a petrol hy­brid, but con­verted into com­pressed air stored in a high pres­sure ac­cu­mu­la­tor (cylin­der) in the cen­tre tun­nel, with a low pres­sure ac­cu­mu­la­tor at the rear axle, and an en­gine/pump as­sem­bly fit­ted to the trans­mis­sion.

The car pro­duces zero emis­sions when run­ning in air mode, and has the ad­van­tage that it does not re­quire the rare earth metals be­ing cur­rently eaten up from the world’s re­serves for the pro­duc­tion of the lat­est gen­er­a­tion of elec­tric mo­tors.

It also doesn’t re­quire heavy and ex­pen­sive bat­ter­ies, and nor does it present a fire risk in the event of an ac­ci­dent.

The air hy­brid sys­tem also takes up less space and weighs much less than an elec­tric hy­brid sys­tem, and nd it al­lows for three modes; Air (equiv­a­lent to a pure ure elec­tric ve­hi­cle), Petrol and Com­bined.

Peu­geot says it will have the ve­hi­cle on the mar­ket in n two years.

The HY­brid Air 2008 also uses Peu­geot’s lat­est lat­est gen­er­a­tion three-cylin­der petrol en­gines, also to be shown at Geneva, among the most eco­nom­i­cal around.

Now that’s a clever use of tech­nol­ogy to save on fuel AND keep the air clean!
