The subject of this thesis is to assessment the impact of supplying a compression-ignition engine with hydrocarbon mixtures and to examine the impact of water on external parameters of the engine, such as smoke opacity. The tests were carried out using a innovative mixture of hydrated fusel oils, ethyl alcohol and ionic and/or non-ionic emulsifiers, from which was made of microemulsions with a water content in diesel oil of 5, 10, 15, 20 and 25%. The main tests were carried out on a 4-cylinder VW 1.9 TDI internal combustion engine at a constant engine crankshaft speed of 3000 rpm and variable load of 0, 30, 60, 90, 120, 150 and 180 Nm. The tests carried out showed a beneficial effect of the water content in the diesel oil on the reduction of the average value of smoke opacity, which systematically decreases with the increase in the percentage of water in the diesel oil.","PeriodicalId":34258,"journal":{"name":"Combustion Engines","volume":"71 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76389913","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 main subject of research is an innovative set of piston rings, the first sealing ring containing a synthetic diamond embedded in a porous chrome coating. The developed multilayer coating is designed to reduce the wear of the piston rings and the combustion engine cylinder. This technology has been implemented at Piston Rings Manufactory \"Prima\" S.A. in Łódź. The tests were carried out using a two-stroke diesel engine of the EMD 645 type. This engine is manufactured by General Motors Corporation in the United States. The described research was carried out in the United States in San Antonio, Texas, at the Southwest Research Institute. The EMD 645 engine is widely used in power units of heavy diesel locomotives and inland waterway barges in the United States of America, India, and South Africa.","PeriodicalId":34258,"journal":{"name":"Combustion Engines","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80312549","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 CAD model was created in the Autodesk Inventor program, and the correctness of its execution was checked by basing it on the scan and generating a scale of deviations along with a color representation of their size in the GOM Inspect program.

Regulations concerning the limiting of vehicle speed to 30 km/h in cities or residential areas are particularly common. This restriction is intended to increase traffic safety, but at the same time introduces increased mileage fuel or energy consumption in electric drivetrain. Regardless of the energy carrier, any increase in energy causes negative effects for the environment. The analysis was focused on the mileage energy consumption of electric passenger cars for a constant speed under real traffic conditions. During the tests, the tested vehicles’ speed on a specially designated road section was changed gradually by 10 km/h, with simultaneous recording of the car’s traction parameters and mileage energy consumption. An analysis of the mileage energy consumption was then carried out for the assumed fleet of cars travelling one after another (in a so-called traffic jam), while maintaining a safe distance. This allowed for the calculation of the environment’s energy burden caused by a fleet of vehicles travelling on a given road section, indicating that a reduction in vehicle speed causes an increase in the vehicles’ energy consumption. Both total and mileage energy consumption of electric vehicles were analysed during the tests.","PeriodicalId":34258,"journal":{"name":"Combustion Engines","volume":"101 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74261820","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 research was performed on automotive engine of Fiat 1100 MPI type. The subject of the performed analysis was to compare operational parameters of the engine such as: engine power output, overall efficiency, emission of toxic components of exhaust gases, as well as comparison of course of combustion process calculated on the basis of recorded and averaged indicator diagrams, and on the basis of individual combustion cycles. The averaged diagrams were used in analysis of the pressure course during combustion, in analysis of pressure growth rate and heat release rate. Diagrams of individual combustion served for assessment of operational smoothness of the engine when fueled with alcohols. As the reference, parameters measured in case of gasoline fueling were used. \u0000The experiments have confirmed stable engine operation on methyl and ethyl alcohols. Increase of engine power output with o 3.8-7.7% was confirmed for methanol and with 1.7-3.3% for ethanol, while increase of the efficiency with 1.5-7.5% was confirmed for methanol and with 1.2-2.5% for ethanol, comparing with gasoline fueling. Obtained results are pointing at possibilities of fueling of modern SI engines with alcohols only, especially including water-logged ethyl alcohol, obtained directly from distillery. This should increase share of alcohols in overall balance of consumed engine fuels.","PeriodicalId":34258,"journal":{"name":"Combustion Engines","volume":"175 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76416375","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 oils were obtained both from urban buses belonging to the fleet of a municipal transport company in Lublin, Poland but also from the city of Pardubice in the Czech Republic. Five samples of 10W/40 semi-synthetic oil and four samples of 5W/30 synthetic oil were tested. Kinematic viscosity at 40°C and 100°C, oxidation, nitration, sulfonation, total acid number (TAN), total base number (TBN), remaining antiwear additives, water content, and glycol content, were assessed using infrared spectroscopy (FTIR). The tests were performed on the basis of the ASTM E2412-10 standard. The article also presents the exceedance of the limit values results for the selected parameters.

Considering the latest trends and regulations, an optimisation model for vehicle selection was developed, considering the issues of emissions and external costs. The developed model was implemented in a simulation environment, and a sensitivity analysis of the solutions obtained was carried out.

The results of the analysis showed that combustion vehicles belong to a conservative market area which promotes the designs that have been thriving for years and maximizes their advantages. Battery electric vehicles belong to an aggressive market area, with the strategy based on a quick response to consumer needs, allowing for the maximization of profits while maintaining innovation.
