Abstract
It has been found possible to achieve fuel savings by heating diesel fuel prior to injection to higher temperatures than those currently used, and in particular, for practical reasons, to temperatures in the range 70.degree. C. to 120.degree. C. However, to obtain the saving it is necessary to simultaneously modify the volumetric flow rate of fuel in order to maintain its mass flow rate in spite of two factors which tend to reduce the effective mass flow rate with increasing temperature, namely: volumetric expansion; and increased fluidity. Not only is fuel saved by heating to such temperatures, but the maximum power and torque which an engine is capable of delivering are also increased.
