本文对现有的内燃机气缸活塞组诊断方法进行了分析和比较。提出了最有希望的诊断方法。所开发的方法可以结合现有和提出的方法的所有积极方面，并解决提高估计 ICE 单元和机制的技术状态的可靠性的问题。作者描述了一个数学模型，考虑了曲轴驱动频率、间隙泄漏、发动机温度、相变过程压力等参数。它可以让您找出燃烧室中的压力变化并将其与实验数据进行比较。利用该方法分析了不同诊断工况下气缸-活塞组的技术状态；分析表明，随着气缸、环和活塞磨损程度的增加，压缩冲程结束时的压力会下降。实验结果以图表的形式呈现，显示了所考虑的过程参数的相互依赖性。
This paper analysis and compares the existing methods for diagnosing the cylinder-piston group of an internal combustion engine (ICE). The most promising diagnosis methods are proposed. The developed method allows to combine all the positive aspects of existing and proposed methods and to solve the problem of improving the reliability of estimating the technical state of ICE units and mechanisms. The authors describe a mathematical model taking into account parameters such as crankshaft motoring frequency, clearance leaks, engine temperature, phase change process pressure. It allows you to find out the pressure change in the combustion chamber and compare it to the experimental data. The proposed method was used to analyze the technical state of the cylinder-piston group under various diagnosis conditions; the analysis revealed that as the wear magnitude of cylinders, rings, and piston increased, pressure decreased at the end of the compression stroke. Experimental results are presented as graphs showing the inter-dependency of parameters of the processes under consideration.
