NEW PROCEDURES FOR MEASURING THE FUEL CONSUMPTION OF CARS

NEUE MESSVERFAHREN FUER DEN KRAFTSTOFFVERBRAUCH VON PKW

Two new measuring procedures, which should give more realistic consumption figures compared with present "stanard consumpitons", are put forward. One deals with a procedure of the European Economic Community (EEC): this procedure is applicable for petrol and diesel engines. The fuel consumption is determined in 1/100 km by way of the following test: a cycle which simulates town traffic; a test with a constant velocity of 20 km/h; a test with a constant speed of 120 km/h. The consumption is determined from the fuel consumption of two successive cycles. The standard consumption for town traffic is the arithmetical mean of 3 successive measurements. For determining the fuel consumption at constant speed four measurements should be carried out, always two above and two below the required reference speeds. In the USA procedure the fuel consumption of a private vehicle is determined from the fuel consumption of the cycle for town traffic (multiplied by 0.55) to which is added the fuel consumption of the cycle for country travel (multiplied by 0.45). The fuel consumption figures for all new usa cars which were determined by this test method were 15.6 1/100 km in 1975 and 12.36 1/100 km in 1977. The limits which are to be kept to by 1985 are shown in tabular form. /TRRL/
