Özellikle yakma sistemlerinin baca ve egzozlarından çevreye yayılan bu kirleticiler insan sağlığını ve canlıların hayat şartlarını olumsuz yönde etkilemektedir. Yapılan bu çalışmada zararlı egzoz emisyonlarını azaltmak amacıyla ayçiçek yağının metil esteri hacimsel olarak %25 oranında dizel yakıtına karıştırılmıştır.  Elde edilen karışım, tek silindirli, hava soğutmalı ve direkt püskürtmeli bir dizel motorun değişik devirlerinde denenmiş olup motorun egzoz gazı emisyonları ölçülmüştür. Bu değerler dizel yakıtı kullanımı ile ölçülen değerlerle karşılaştırılmıştır. Deney sonuçları dizel yakıtına göre karışımda kirletici emisyon miktarlarında bir düşüş olduğunu göstermiştir. Maksimum moment devrinde dizel yakıtına göre CO miktarı %21, NOx miktarı %11, maksimum güç devrinde ise CO %7, NOx’in % 12 azaldığı görülmüştür. Araştırma sonucunda, bitkisel yağların esterleri alternatif yakıt olarak dizel araçlarından kullanılmasının çevre açısından olumlu olduğu sonucuna varılmıştır.", "language": "tr", "english_title": "The Investigation of Decrease Harmful Exhaust Emissions on a Diesel Engines", "english_abstract": "The matters that cause to air pollution is expanded to atmosphere in everywhere is produced energy in the world.

In this study, to aim to decrease harmful exhaust emissions sunflower oil methyl ester was mixed volumetrically with diesel fuel in %25 proportion. The mixture was tested in four stroke, air cooled, direct injection diesel engine with single cylinder in different speed (rpm) and emission values were measured. These values were compared with the ones for diesel fuel. The results showed that the mixture of sunflower oil methyl ester and diesel fuel gave a power and torque close to the values obtained from the diesel fuel and the amounts of pollutants decreased. At the maximum torque, amount of CO and NOx decreased 21% and 11% respectively. Similarly, they decreased 7% and 12% at maximum power speed. As a result, considering the exhaust gas emissions it was seen that sunflower oil methyl ester and diesel fuel mixture could be used as an alternative fuel in a diesel engine.", "doi": "10.36287/setsci.4.6.148", "doi_url": "https://doi.org/10.36287/setsci.4.6.148", "resource_url": "https://www.set-science.com/a/bf11293f-3c73-4c71-8867-b2d32c845d0a", "pdf_url": "https://www.set-science.com/a/bf11293f-3c73-4c71-8867-b2d32c845d0a/pdf", "og_image": "https://www.set-science.com/assets/img/og-card-v2.png", "authors": [ { "public_id": "052fcc87-b2a6-42b2-b77e-faab3609d7f2", "given": "Zeynep", "family": "İlkılıç Aytaç", "full": "Zeynep İlkılıç Aytaç", "literal": null, "orcid": null, "orcid_url": null, "email": "zeynep.ilkilic@omu.edu.tr", "corresponding": true, "sequence": "first", "affiliations": [ { "name": "Ondokuz Mayıs University", "department": null, "country": null, "country_code": null, "ror": null, "ror_url": null } ] }, { "public_id": "0d11c9d0-af51-47e9-8d99-b7725384fef9", "given": "Cumali", "family": "İlkılıç", "full": "Cumali İlkılıç", "literal": null, "orcid": null, "orcid_url": null, "email": "cilkilic@firat.edu.tr", "corresponding": false, "sequence": "additional", "affiliations": [ { "name": "Fırat University", "department": null, "country": null, "country_code": null, "ror": null, "ror_url": null } ] } ], "keywords": [], "translations": [ { "language": "en", "title": "The Investigation of Decrease Harmful Exhaust Emissions on a Diesel Engines", "abstract": "The matters that cause to air pollution is expanded to atmosphere in everywhere is produced energy in the world.
