ENERGY CONSUMPTION IN ROAD TRAFFIC

VAGTRAFIKENS ENERGIFORBRUKNING

This study deals with the fuel consumption of different types of motor vehicles. Its dependence on different factors is studied on the basis of literature and measurements. In addition, a proposal has been made to measure a passenger car's fuel consumption by the ECE-method. The following could be found to save a passenger car's fuel consumption, the total effect of which is estimated at 500-580 mill. Litres for the forecast of 1990: - decreasing of motor displacement by 100 cm3 - decreasing the average weight by 100 kg - decreasing the average air friction coefficient by 10% - decreasing the average travel speed on highways by 5 km/h - use of radial tyres only - use of synthetic lubricants only - further driver education - general education in vehicle- and traffic techniques - use of electrical warmers before cold starts. Further a group of possibilities could be named that are difficult to estimate, like better roads, transmission ratios better suited to road circumstances and speed limits, increasing the level of vehicle service, and increasing the average effectiveness of car use. With commercial vehicles, a minor saving could be found in vehicle technology. The greatest saving in this sector lies within a more effective use of vehicles. The ECE-method has been applied to measuring a passenger car's fuel consumption. The automobile laboratory at the Helsinki University of Technology is ready to measure fuel consumptions by this method. (TRRL)
