Abstract
Hot fuel handling problems of the motor car have engaged the automotive engineer and gasoline refiner since the 1930s. The subject has received considerable attention in the USA and interest in Europe has increased with the need to market cars world-wide. This paper discusses fuel and engine design features associated with the hot fuel handling performance of European cars and includes suggestions on test locations and procedures. Vehicle design features affecting hot fuel handling performance have changed significantly in recent years resulting in the need to improve vapour tolerance. Vehicle design features conducive to good hot fuel handling performance have therefore been enumerated, with particular emphasis being given to the design of mechanical fuel pumps, the component from which most benefits would be reaped by further development. In the future, there will be a need for still closer cooperation between the oil and motor industries to achieve optimum use of natural resources and to provide maximum benefit to the vehicle user.
