CHANGES in the recomme dations for improving ft consumption on vehicles ha been made by the Advisc Council on Energy Cons■ vation's Transport Worki Group.
Published this week, th include the admission that hope for the introduction spark-assisted or opE chamber stratified engin may have been "ov, optimistic".
The group feels that t reciprocant piston inter' combustion unit will be t dominant power unit I goods vehicles until the turr the century — but 14 vehicles may be going over battery power more and mc Tax differentials for die powered engines to favour diesel are now recommendE But the group warns tl improvements in efficiency engines sometimes leads more and more fumes bui admits that these are harmful and that reductior fumes could lead to lowe fuel economy.
And it adds that propo: European emission contr should not be made stringent that they cause creases in fuel consumpti until evidence of harm fr emissions is available.
Efforts to reduce aero namic drag are also enc raged and vehicle weights not gross weights — shoulc reduced by using ligh materials.
The new recommendati say that radial tyres shoulc used to reduce rolling res ance.
And the group also want see more efforts to educ drivers in more econom driving and a restraint on power output of vehic under normal driving coi tions.
