Potential for cutting lorry emissions
A study commissioned by the International Council on Clean Transportation says using low-resistance tyres, aerodynamic devices and lower weights can improve the fuel efficiency of lorries by between 4% and 10%.
The report, done at the Technical University of Graz, is based on tests of fuel efficiency improvements arising from better trailer and tyre designs. Air resistance and adhesion between tyres and road surfaces were also looked at, using a new test procedure that involved constant speeds and slowing down, with the results confirming the potential for lower emissions. The authors say the test procedures need further refining before they can be used for certification or type approval.
