TESTING AND DEVELOPMENT OF MEASURES FOR REDUCING THE AERODYNAMIC RESISTANCE IN DRIVING TESTS AND COST - BENEFIT ANALYSIS

ERPROBUNG UND ENTWICKLUNG LUFTWIDERSTANDSVERRINGERNDER MASSNAHMEN IN FAHRVERSCUCHEN UND KOSTEN-NUTZEN-BETRACHTUNGEN

The proportion of the total fuel consumption of a 38 ton lorry which is required to overcome the aerodynamic resistance amounts to 30% on average, i.e. 12-15 l/100 km. This report covers the conditions of the test drive and the results using two lorries, for which the influence of the various test components for the reduction of aerodynamic resistance on the fuel savings was measured. The items tested included wind deflectors, frontal aprons, suitably contoured wings, the omission of side coverings on lorries and trailers and the fitting of frontal covers to trailers with "noses". The savings amounted on average to approximately 0.8 l/100 km. Examination of the cost benefit relationships for the fitting of additional components and (TRRL)
