摘要

世界范围内的环境恶化、全球变暖、化石燃料的稀缺等问题已经导致内燃机汽车被电动汽车所取代。对于经济不发达的国家来说，寻找更经济的方式来解决这个问题是很重要的。其中之一是将内燃机汽车转变为更环保、更经济的汽车，比如汽油动力汽车。然而，柴油汽车的转换通常会导致功率损失。发动机供电系统电磁配气器(EGD)的工作状态对燃气发动机的工作效率有重要影响。因此，本研究的目的是确定KrAZ卡车(乌克兰)转化为天然气的EGD的动态和流动特性，并为提高其运行效率提供建议。研究对象为6ChGN13/14发动机EGD供电系统的工作过程，该系统由柴油机改造而成，安装了燃气轮机增压器。本文介绍了确定工作电压对EGD动态特性影响的实验研究结果。得到了EGD动态特性和流动特性与控制信号频率变化的关系，以及通过EGD喷嘴的效率与控制信号持续时间的关系;确定了回弹刚度对EGD动力特性和流动特性的影响。这项工作的结果旨在提高柴油卡车转换为汽油的效率。

Estimating Dynamic and Flow Characteristics of Electromagnetic Dispenser for The Kraz Truck Converted to Gas

The problems of worldwide environmental degradation, global warming, scarcity of fossil fuels hascaused the replacement of ICE vehicles with electric ones. For the countries with underdeveloped economy, it is important to find more affordable ways to solve this problem. One of them is to convert the cars with ICE into more environmentally friendly and economical ones, such as gas-powered cars. Yet, the conversion of diesel cars usually results in power loss. The work of the electromagnetic gas dispenser (EGD) of the engine power supply system significantly affects the efficiency of the gas engine. Therefore, the aim of the study was to determine the dynamic and flowcharacteristics of the EGD of the KrAZ truck (Ukraine) converted to gas, and to provide recommendations for improving the efficiency of its operation. The object of the research was the working processes of the EGD power supply system of 6ChGN13/14 engine, converted from diesel engine and equipped with a gas turbine supercharger. The paper presents the results of experimental studies on determining the effect of operating voltage on the dynamic characteristics of EGD. The dependences of dynamic and flow characteristics of the EGD on the change of the control signal frequency and the dependence of efficiency through the EGD flow nozzle on the control signal duration were obtained; the effect of the return spring stiffness on the dynamic and flow characteristics of the EGD were determined. The results of the work are designed to increase the efficiency of diesel trucks converted to gas.
