Effect of cottonseed oil methyl ester on the performance and exhaust emissions of a vehicle / Bir Taşıtın Performans ve Egzoz Emisyonları Üzerine Pamuk Yağı Metil Esterinin Etkisi

The present work investigates the impact on vehicle performance and exhaust emissions from vehicle when using 100% diesel with petroleum origin (fossil diesel), compared to a mixture of 2-5-100% cottonseed oil methyl ester (COME) in fossil diesel fuel (B2, B5, B100). For the accomplishment of this work an assessment was made using some primary tests on a chassis dynamometer, measuring vehicle performance and emissions. The results demonstrate that the use of biodiesel has a negative effect on vehicle's performance. The increase in average fuel consumption was approximately 1.44 fold for usage of B2, B5 and B100 at forth gear. According to results of exhaust emissions from vehicle, the decrease in average CO emission was approx. 47.2% for usage of B100. Ozet: Mevcut calisma fosil dizel yakitinda (B2, B5, B100) pamuk tohumu yagi metil ester (COME)’in % 2-5-100 karisimina kiyasla % 100 petrol kokenli dizel (fosil dizel) kullanan, aracin, arac performansi ve egzoz emisyonlarina etkisini arastirmaktadir. Bu calismanin gerceklestirilmesi icin arac performansi ve emisyon olcum, bir sasi dinamometre uzerinde bazi temel testler kullanilarak bir degerlendirme yapilmistir. Sonuclar biyodizel kullaniminin aracin performansi uzerinde olumsuz bir etkiye sahip oldugunu gostermektedir. Ortalama yakit tuketimindeki artis ileri viteste B2, B5 ve B100 kullanimi icin yaklasik 1.44 kat olmustur. Aracin egzoz emisyon sonuclarina gore, ortalama CO emisyonundaki azalma B100 kullanimi icin yaklasik % 47,2 olmustur.
