Original results were obtained for the parameters of an engine fueled with six fuels differing in chemical composition: the base fuel (F-54 diesel), F-34 aviation fuel, and four blends formed from F-34 fuel and RME (Rape Methyl Ester - rapeseed oil fatty acid methyl esters) with different weight percentages in the blend. Studies of blends of jet fuel with biocomponents in a wide range of shares in military fuel applications are not found in the available literature. The performance of the tested engine changed significantly. A decrease in useful power of about 3 % was obtained when the engine was powered by aviation fuel, compared to an engine powered by diesel fuel. For mixtures of aviation fuel F-34 with RME, the decrease is 5–10 %, depending on the content of RME in the mixture. Specific fuel consumption is higher for blends with methyl esters, and the increase is proportional to the RME content in the blend, ranging from 6 to 12 % depending on the proportion of RME, resulting in increased fuel demand. Supplying the engine with mixtures of F-34 fuel with RME resulted in an increase in average CO<sub>2</sub>, CO and HC emissions in the range of 12–18 %. The addition of RME to F-34 fuel resulted in an almost 3-fold reduction in smoke opacity compared to powering an F-54 engine, a phenomenon that is very beneficial from an environmental perspective. It is possible to use mixtures of F-34 jet fuel with RME to power modern internal combustion engines with common-rail power systems, which expand the fuel range during armed conflicts.</div></div>","PeriodicalId":326,"journal":{"name":"Fuel Processing Technology","volume":"275 ","pages":"Article 108254"},"PeriodicalIF":7.2,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144195146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite notable progress, there remains a need to expand the range of feedstocks, optimize technological pathways, and scale up new fuel production. The authors propose developing novel biojet fuel in response to these challenges. The work presents complex research on the synthesis of renewable fuel components, the study of basic physical-chemical properties of new biojet fuel, and the assessment of gas turbine engine operation parameters to validate the hypothesis that this fuel can be used for jet engine propulsion with the required efficiency. Coconut oil ethyl esters (COEE) used as a renewable component were synthesized via esterification of coconut oil with ethanol and refined via vacuum distillation. The choice of the feedstock and production method allowed the production of a product with a high level of purity (97.4 %) of COEE, a light molecular weight composition (C6-C18) close to conventional jet fuel, and a low content of unsaturated fatty acids (below 5 %). The study of basic physical-chemical properties of biojet fuels containing traditional jet fuel and 10 %, 20 %, and 30 % of COEE demonstrated the rise of density by 1.01–2.53 %, viscosity by 9.79–32.26 %, freezing point by 10.34–33.51 %, and reduction of combustion heat by 1.69–5.07 %.
