最近的许多工作都涉及到燃料成分对火花点火发动机的规定和特定污染物排放的影响。虽然已经提出了许多定性相关性，但已知的定量相关性很少（苯仍然是一个例外）。本文描述了火花点火发动机的燃料成分与特定污染物排放（单个碳氢化合物、醛类、酮类、醇类和有机酸）之间的定性和定量关联。这项工作的目的是找到主要特定污染物的前体。然后，对它们中的每一种，计算出一个多元线性方程，说明其在废气中的浓度与燃料中的含量之间的关系。这些计算结果指出了哪种初始化合物有利于形成确定的污染物。由于未来的商用发动机可能会采用精益工况，因此在相当大范围内（从0.8到1.2）对燃油效应进行了研究。
Many recent works have dealt with the influence of fuel composition on regulated and specific pollutant emissions from spark ignition engines. While many qualitative correlations have been already proposed, only a few quantitative ones are known (benzene remains an exception). This paper describes qualitative and quantitative correlations between fuel composition and specific pollutant emissions (individual hydrocarbons, aldehydes, ketones, alcohols, and organic acids) of a spark ignition engine. The aim of this work was to find the precursors of the main specific pollutants. Then, for each of them, a multilinear equation has been calculated, illustrating the correlation between its concentration in exhaust gases and its content in the fuel. The results of these calculations point out which initial compound favors the formation of a determined pollutant. As lean conditions are probably going to be used in future commercial engines, the fuel effect has been studied for a broad range of equivalence ratios (from 0.8 to 1.2).
