Investigations on Performance and Emissions of a Stationary DI Diesel Engine with Different Exhaust Gas Recirculation Temperatures / Farklı Egzoz Gazı Devir Daim Sıcaklıkları ile Yerleşik Bir Dizel Motorun Emisyon ve Performans Üzerine Araştırmalar

Öz This paper addresses the application of exhaust gas recirculation (EGR) for reduced oxides of nitrogen (NOx) emissions from naturally aspirated direct injection stationary diesel engine. Prevailing and future Emission norms compel engine manufacturers to incorporate techniques to reduce engine out emissions especially NOX and particulate matter NOx formation predominantly depends on high combustion temperature and literature indicates EGR is an attractive method to reduce combustion temperature. EGR temperature is an important factor while admitting higher percentage of EGR. Higher EGR temperatures caused due to increased loads limit the conduct of higher EGR ratios. EGR cooling can be advantageous when higher ratios of EGR need to be employed. The effect EGR temperature on engine thermal efficiency, NOx, smoke and HC emissions at different load conditions for different EGR percentage are discussed in this paper. NOx reductions and thermal efficiency were found to be better for hot EGR up to about 30% EGR and thereafter EGR cooling shows better results. Smoke and HC emissions increase for both cooled and hot EGR as compared to no EGR case but EGR cooling reduces HC emission as compared to hot EGR. Özet: Bu çalışma doğal emmeli direk enjeksiyonlu yerleşik dizel motordan salınan azot oksitler için egzoz gazı devirdaim uygulamalarına hitap etmektedir. Yaygın ve gelecek emisyon normları motor üreticilerini özellikle azot oksitleri emisyonunu azaltmak için teknikleri bünyesinde bulundurmayı zorunlu kılmıştır ve parçacıklı madde azot oksit oluşumu büyük oranda yüksek yanma sıcaklığına bağlıdır ve literatür EGR’nin yanma sıcaklığını azalttığına dair etkin bir metot olduğunu gözterir. EGR sıcaklığı daha yüksek EGR yüzdesine meydan verirken önemli bir faktördür. Artan yüklerden kaynaklı yüksek EGR sıcaklığı yüksek EGR oranı üretimini kısıtlar. EGR soğutma yüksek oranda EGR çalıştırma ihtiyacı olduğu zaman avantajlı olabilir. EGR sıcaklığının motor ısıl etkinliği, farklı EGR yüzdesi için farklı yükleme koşullarında NOx, duman ve HC salınımları bu çalışmada tartışılmıştır. NOx azaltması ve ısıl verimlilik sıcak EGR için %30 EGR ye kadar daha iyi bulundu ve sonra EGR soğutma daha iyi sonuçlar gösterir. EGR siz kasa ile kıyaslandığında duman ve HC emisyonları hem soğutulmuş hem de sıcak EGR için artar fakat EGR soğutma sucak EGR ile kıyaslanırsa HC emisyonunu azaltır.
