【Abstract】 In this paper, the experiential formula of fuel density variation with pressure and temperature is put forward and the experiential formulas of fuel compression ratio and sonic velocity are also derived in light of the strict relationships of fuel parameters, and besides, the viscosity experiential formula is recommended. The experiential formulas offered in this paper possess high precision according to the experimental results.更多还原
