The choice of the set of tools for studying physical and chemical properties is due to their small size and the small amount of time devoted to studying their primary structure, since they undergo changes in the future. The paper presents some of the results of such studies. The results give better understanding of the morphology of carbonaceous particles, and thus the mechanisms of their formation and oxidation. Particular attention is paid to the internal structure of the particles, which determines their properties, reactivity, and ways of further development. We draw the conclusions upon the effectiveness of the considered methods for determining the internal structure of solid carbonaceous particles, the main properties of particles obtained by burning diesel fuel, as well as using alcohols and compounds based on them as fuel. It is shown that the molecular and atomic structure of carbon particles has a multilayer structure affecting the ability of these particles to participate in further reactions.","PeriodicalId":282212,"journal":{"name":"Engines Construction","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124146268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the effective ways to solve this problem is piston skirt profiling. Profiling is aimed at creating conditions for fluid friction in the “piston skirt-cylinder” interface with minimal mounting clearances. We present a mathematical model for studying the influence on the hydrodynamic characteristics of friction and the dynamics of the movement of the piston of the main parameters characterizing the design of the details of the crank mechanism. This model includes a coupled solution of interrelated problems: determining the characteristics of the transverse movement of the piston, the deformation of the piston skirt under thermal and mechanical loads, and the calculation of the hydrodynamic forces acting from the oil layer in the fit. The results are obtained for a two-piece piston with a diameter of 130 mm. We study the influence of the profile of the two-piece piston skirt on the hydrodynamic characteristics and the transverse movement of the piston is studied and present the results for the considered design. Lastly, we give recommendations for profiling.","PeriodicalId":282212,"journal":{"name":"Engines Construction","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132178776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper presents additions to the mathematical model of fuel supply in a diesel accumulator system. These additions describe the deformation of the injector parts. The longitudinal compliance of the parts changes the course of the needle, the volume of the cavities. As shown by the analysis of the operation of three electro-hydraulic injectors, longitudinal compliance leads to an increase in the injection start delay up to 2,0...2,5° of the camshaft turn, an increase in the needle stroke up to 40 %, an increase in injection pressure, a reduction in its duration, and difficulty in organizing multiple fuel injection. The comparison with experimental data and finite element calculations showed the applicability of the supplemented mathematical model as a part of the general model of fuel injection in diesel systems. Its use allows creating more valid tools for calculating fuel supply processes and taking into account compliance when designing Common Railinjectors.","PeriodicalId":282212,"journal":{"name":"Engines Construction","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130546081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
