THE HOT-FUEL HANDLING PERFORMANCE OF EUROPEAN AND JAPANESE CARS
Extensive tests were carried out with European and Japanese cars to investigate the occurrence of vapor lock and related problems under hot-weather conditions. Different criteria, based on gasoline inspection properties, were evaluated for their ability to control hot-fuel handling performance. Considerable market experience was accumulated with the flexible control, RVP (mbar) plus 7E70, which is preferred to the Vapor/liquid ratio type of control because it is far easier to use in routine refinery applications and to control. However, the two types of control are equivalent in their ability to predict the performance of a wide range of gasolines, including those which may result from reductions in lead content. In their tolerance to gasoline volatility, the European and Japanese cars are very similar to the catalyst-equipped California models tested by the CRC in 1975. In developing new car models, careful consideration should be given to minimizing the effects of some emission control systems and engine ancillaries in the fuel system, effects which may worsen a car's hot-fuel handling performance.
