METHOD AND SYSTEM FOR DETERMINING VOLATILITY OF FUEL

摘要

PROBLEM TO BE SOLVED: To eliminate at least partially default found in the prior art.SOLUTION: This invention relates to a method for determining a volatility of fuel within a fuel storage system comprising a step for determining occurrence [210] of fuel supplementing and subsequently determining that a fuel storage system is tightly closed [220]; a step [230] for performing a first pressure measurement within the fuel storage system at a first time after the step of determining; a step [240] for performing a second pressure measurement within the fuel storage system at a second time occurred after the first time; a step [250] for determining a pressure developing speed in reference to the first pressure measurement at the first time and the second pressure measurement at the second time; and a step [260] for guiding estimation of fuel volatility in reference to the pressure development speed.SELECTED DRAWING: Figure 2
