燃料热值

[中文适用范围]： 热值或燃烧热是燃料可用能量的量度。转化为有用功的燃烧热的分数或百分比是发动机热效率的衡量标准。因此，了解燃料燃烧热是汽车发动机工程的基础。本 SAE 信息报告提供了有关确定可用于汽车发动机的燃料燃烧热的标准化程序的信息。 SAE J1498 的变更包括： SAE 出版物 - 添加了 SAE 论文 2010-01-1517 其他出版物和第 5@、9@ 和 10 节 - 更新了 ASTM 字母数字名称和标题。第 10 节 - 添加了对使用 ASTM D3338 计算汽油-乙醇混合物净热值的方法的讨论。 [外文原描述]： The heating value or heat of combustion is a measure of the energy available from the fuel. The fraction or percentage of the heat of combustion that is converted to useful work is a measure of the thermal efficiency of an engine. Thus, a knowledge of the heat of combustion of the fuel is basic to the engineering of automotive engines. This SAE Information Report provides information on the standardized procedures for determining the heat of combustion of fuels that may be used for automotive engines.The changes to SAE J1498 include:SAE Publications - Added SAE Paper 2010-01-1517Other Publications and Sections 5 , 9 , and 10 - Updated ASTM alphanumeric designations and titles.Section 10 - Added discussion of a method to calculate net heating value for gasoline-ethanol blends using ASTM D3338.Cross Reference: 2010-01-1517,ASTMD1018,ASTMD1405,ASTMD1826,ASTMD1945,ASTMD1946,ASTMD240,ASTMD2421,ASTMD2650,ASTMD3338,ASTMD3588,ASTMD3701,ASTMD4529,ASTMD4809,ASTMD4868,ASTMD5865,ASTMD86,ASTME711,ASTMSI10,J313_201706,TSB003
