36、 The significance of each of the properties of this specification is shown in Appendix X1.5.1.1 The user is advised to review applicable national, state, provincial, or local fuel requirements.5.1.1.1 In the United States there may be additional Clean Air Act requirements that must be fulfilled prio

For a specification limit expressedas an

39、 integer, a trailing zero is significant only if the decimal point is specified. For a specified limit expressed as an integer, andthe right-most digit is non-zero, the right-most digit is significant without a decimal point being specified. This convention appliesto specified limits in Tables 1 and

40、 2.5.2 RON and octane sensitivity are critical performance parameters for the fuels described in this specification. Engine knockand laboratory octane number are described in X1.2 and X1.3, respectively.5.2.1 For engines with increased compression ratio, higher boost pressure, operating at slower sp

41、eeds, and smaller sweptdisplacement volume, a high RON, combined with high octane sensitivity, are well correlated with knock resistance.5.2.2 Octane sensitivity is the mathematical difference between the research and motor octane numbers and is considered ameasure of the autoignition temperature se

42、nsitivity of a fuel. In high compression ratio, highly boosted engines operating at lowengine speeds, if RON is held constant, a fuel with greater octane sensitivity (all other factors being equal) will provide greaterknock resistance.5.2.2 A minimum motor octane number (MON) is required to ensure a
