Summary:

Motor and Oil industries in Europe continue to recongnize the need to establish realistic test procedures to evaluate the driveability performance of cars and fuels. Accordingly, representatives from both industries have been working together in the CF24 Group, formed in 1978 under the auspices of the Coordinating European Council (CEC), to develop standard driveability test methods.While CF24's tasks and preliminary achievements were first outlined to the SAE in 1981, this paper describes the Group's more recent field test in Sweden and chassis dynamometer work throughout Europe, which has led tho the establishment of a European cold weather driveability test procedure.The method provides a means of assessing engine starting, idling, and drive quality during the warm-up phase, and is capable of distinguishing between fuel volatility, vehicle design characteristic, and ambient air temperature effects. Acceptable test precision and road/chassis dynamometer correlation has been fully demonstrated, but it is felt that driver training is an essential feature of the method if optimum benefit from its use is to be obtained.As motor vehicle design trends in the USA approach those of Europe, the need for similarity between the driveability test procedures used on both sides of the Atlantic is becoming obvious, as is the need for forging closer links between the CRC and CEC organisations which have similar goals
