闭式循环条件下内燃机燃油和工质物性计算

摘要

Abstract： As the special composing of material in cylinder in the closed cycle diesel, the method of using the property of mixture of C16H34 and C11H10 to replace that of the fuel is presented, and the gas material in cylinder is consisted ofO2, N2, H20, CO2, Ar, C16H34 and C11H10. At the same time, the method for calculation of physical property parameters of fuel and gas material in cylinder is given. The method is verified to be correct and practical by testing.%针对闭式循环条件下，缸内工质的特殊构成，提出用正十六烷和α-甲基萘按适当比例混合的混合物来模拟燃油，认为缸内燃烧过程的气态工质由氧气、氮气、水蒸汽、二氧化碳、氩气、正十六烷和α-甲基萘所组成。同时，给出了燃油和缸内工质物性计算所应采用的方法。经验证，方法是正确的、可行的。
