目前全世界都认为，良好的喷油规律可能使NOx排放量和燃烧噪声降低，且不会对油耗量和颗粒排放造成不良影响。李斯特内燃机研究所（AVL）的这篇文章描述了混合气的形成是对喷油规律起决定作用的因素，也叙述了实现某一喷油规律时可能出现的几个典型的喷油过程及其对NOx和碳烟（颗粒）排放所起的影响。对得出的结果进行分析后表明，随着废气再循环量的增加，对与此相适应的喷油规律方面的要求越来越高，这样才能圆满地达到所期望的运动效果。
The world now believes that good fuel injection laws may reduce NOx emissions and combustion noise without adversely affecting fuel consumption and particulate emissions. This article from the Liszt Institute of Internal Combustion Engineers (AVL) describes the formation of a mixture as a contributing factor to the law of fuel injection. It also describes several typical fuel injection processes that may occur when implementing a fuel injection rule and Its impact on NOx and soot emissions. Analysis of the results obtained shows that as the amount of exhaust gas recirculation increases, there is an increasing demand for fuel injection laws that correspond to this, so that the desired effect of exercise can be satisfactorily achieved.
