The modification of fuel properties has drawn much attention since these methods offer additional potential to reduce emissions. Oxygenated fuels are reported to greatly diminish particle emissions while water emulsification of regular diesel causes a significant decrease in NOX. However, recent studies indicate that these fuel-based approaches may lead to an increase in nanoparticle emissions, which are known to be more dangerous to human health than large particles. This has raised the question about whether current engine technology is prone to nanoparticle formation.In this work, the authors present a detailed study on combustion and emission performance of the oxygenate fuel Oxymethylene Ether (OMEn, the mixture contains neat OME with chain length n = 2 − 6). In a novel approach, a single-cylinder heavy-duty diesel engine was fueled with both neat and water-emulsified OME to combine the two fuel-based methods in order to simultaneously reduce both NOX and particle emissions to a great extent. Particular emphasis was put on the particle size distribution (PSD) of emitted PM to elaborate a potentially severe drawback of these fuel-based approaches. In the process, hydrogenated vegetable oil (HVO) was used as the diesel reference fuel. The findings are summarized as such: PSD measurements of OME2-6 reveal similar particle diameters in mid-load operation and a shift to smaller particles at unfavorable engine operations compared to HVO. Water-emulsified OME2-6 reduces NOX by roughly 2-3% with a one percent increase in water concentration while maintaining a nearly constant combustion efficiency. Adverse effects on nanoparticle formation by water emulsification were not observed.","PeriodicalId":21365,"journal":{"name":"SAE International Journal of Fuels and Lubricants","volume":"13 1","pages":"187-203"},"PeriodicalIF":1.0,"publicationDate":"2020-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49598944","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}

Cousseau, Giuseppe Pintaude","doi":"10.4271/04-13-02-0010","DOIUrl":"https://doi.org/10.4271/04-13-02-0010","url":null,"abstract":"With the trends to increase drain oil interval to reduce cost of ownership of Heavy-Duty vehicles and to use low ash oils, the efficiency of lubricant additives, especially the anti-wear ones, are of great interest. However, most of tribological tests are still done with fresh oils or in a few cases with artificially aged oils. In this work, piston ring and cylinder liner were rig tested for friction and wear on a short reciprocating tester with two oils: a fully formulated SAE 10W-40 API CI-4 / ACEA E7 and a sample of the same oil after 500h of engine test. Liner wear was evaluated by different parameters based on the Bearing Curve. Higher cylinder wear and slight lower friction values were found with aged oil. Samples of a liner with accumulated 500 engine hours were also tested with the aged oil and showed intermediate results. Figure 1Liner wear. After test, wear track of cylinder liners was analyzed by EDS (Energy Dispersive X-Ray Spectrometry) and compared with analyses of the parts before test. Much more Zinc and Phosphorus were found on the liners tested with fresh oil. Figure 2Liner wear and % of Zn+P found in the wear track. CONCLUSIONS: Compared with the fresh oil, the aged oil showed slight lower friction but significant higher liner wear. More Zinc and Phosphorus were found on the liner wear track of the liners tested with the fresh oil. The fresh oil formed more ZZDP derived tribofilms that mitigated liner wear but increase friction. The used liners, tested with the aged oil presented intermediate values of friction, wear and ZDDP tribofilms.
