摘要： Gasoline fuel formulation having a laminar burning velocity SL which is equal to or below that of isooctane at a pressure of 1 bar, a temperature of 300 K and stoichiometric air/fuel mixture strength. The formulation can be used to reduce pre-ignition in a turbocharged spark ignition engine, in particular when operating with an inlet pressure above 1.5 bar absolute. The formulation can thus also be used to reduce engine damage. The invention also provides a method of preparing a gasoline fuel, by mixing gasoline fuel components to achieve a laminar burning velocity SL for the resultant mixture which is equal to or below that of isooctane at a pressure of 1 bar, a temperature of 300 K and stoichiometric air/fuel mixture strength. It further provides a method for selecting a gasoline fuel for use in a turbocharged spark ignition engine, based on its laminar burning velocity SL.
摘要翻译：汽油燃料配方具有等于或低于异辛烷的层压燃烧速度SL，压力为1巴，温度为300K，化学计量空气/燃料混合物强度。该配方可用于减少涡轮增压火花点火发动机中的预点火，特别是当进口压力高于1.5巴绝对值时进行操作。因此，该配方也可用于减少发动机损坏。本发明还提供一种制备汽油燃料的方法，通过混合汽油燃料组分以达到所得混合物的层流燃烧速度SL等于或低于异辛烷的压力为1巴，温度为300K，化学计量空气/燃料混合物强度。它还提供了一种基于其层流燃烧速度SL来选择用于涡轮增压火花点火发动机的汽油燃料的方法。
