摘要

该研究的目的是介绍与使用为发动机提供动力的各种燃料有关的车辆动力学变化。本文介绍了液化石油气和生物二甲醚混合气体燃料对车辆灵活性的影响。在以前的研究中，没有太多关注随着供应发动机的各种燃料的使用而改变车辆性能的问题。这是一种新的方法，可以确定使用替代燃料的优点和缺点，包括使用生物二甲醚的混合物。该研究是针对安装在乘用车中的排量为1.6 dm3的四缸SI发动机进行的。对LPG和DME的混合物进行了评估，并将结果与LPG动力发动机获得的参数进行了比较。接收到的结果可以确定选定发动机负载和混合物中各种DME份额的发动机灵活性值的变化。二甲醚可以被认为是燃烧过程的激活剂，并可能对车辆动力学产生影响。

ENGINE FLEXIBILITY FOR SI ENGINES FUELED BY LIQUID GAS WITH DIMETHYL ETHER BLEND

The aim of the study is to present the changes in the vehicle dynamics that occur in connection with the use of various fuels that power the engine. The article presents the effect of gaseous fuels being mixtures of LPG and BioDME on the flexibility of the vehicle. In previous studies, not much attention has been paid to the problem of changing the performance of the vehicle with the use of various fuels supplying the engine. It is a new approach that allows to determine the advantages and disadvantages of using alternative fuels, including mixtures using BioDME. The study was conducted for a four-cylinder SI engine with a displacement of 1.6 dm3, installed in a passenger vehicle. The mixture of LPG and DME was assessed, and the results compared to the parameters obtained for the LPG-powered engine. Received results have been made it possible to determine changes in the value of the engine flexibility for selected engine loads and various DME shares in the mixture. The thesis that DME can be considered as an activator of the combustion process and may have an impact on the vehicle dynamics is confirmed.
