ENERGY SAVING - THE NEGATIVES AND POSITIVES

The article is an analysis of the one-day June conference organised by the 'Commercial Motor' in London. Major topics discussed were the potential energy savings of increased maximum gross vehicle weights to 42/44 tonnes, and the proposal that road wear should be assessed on dynamic axle loads and not static axle weights as at present. A modified formula was presented - still using the fourth power law - but compensated by factors to account for the unsprung weight, the type of suspension, whether dampers were fitted or not, the type of tyre fitted and its inflation pressure. The cost effectiveness of speed restrictions in the United States were discussed, fuel consumption was reduced but other operating costs were increased. Designs of engines and transmissions were explained. It was also pointed out that commercial transport took only six per cent of the UK national oil consumption, and that other factors such as optional routeing and better roads for city access could also produce large savings. /TRRL/
