摘要 液化石油气（LPG）供应系统的实施问题与以下事实有关：它们是为与其他种类的燃料一起工作而构造和优化的发动机中使用的替代系统。因此，系统组装商必须评估功率损耗，同时评估生态要求。该实验致力于分析发动机在不同模式下的气体成分，以明确LPG系统调节的特殊性，并为数值汽车动力学模型评估环境污染获得数据。据估计，目前LPG系统的算法平衡了生态要求和发动机外部特性的优化，并且燃气系统具有大惯性的特点。此外，还确定必须构建更精确的调整算法，并且必须预见当发动机在标准模式下工作时更多的调整点和调整。
Abstract The problems of implementation of liquefied petroleum gas (LPG) supply systems are related with the fact that they are alternative systems used in engines constructed and optimized for work with other kinds of fuel. So assemblers of the systems have to evaluate power losses and at the same time ecological requirements. The experiment is devoted to the analysis of gas composition of engines working at different modes in order to specify the particularity of LPG system tuning and to obtain data for the evaluation of environmental pollution by numerical car dynamics models. It is estimated that the algorithms of current LPG systems balance between ecological requirements and optimization of external characteristics of engines, and the gas systems are characterized by a great inertia. Also, it is determined that more precise tuning algorithms must be constructed, and more tuning points and tuning, when an engine works in standard modes, must be foreseen.
