Bir dizel motorunun bilgisayar yardımı ile termodinamik ve performans analizi
(Gazi Üniversitesi, 2013)Bu çalışmada, dört zamanlı, tek silindirli, normal emişli, direkt püskürtmeli bir dizel motorunun çevrim analizi için MATLAB programında bir simülasyon geliştirilmiştir. Simülasyon sonucunda; tam yükte krank mili açısına ... -
Üç-fazlı dizel emülsiyon yakıtlarının motor performansı ve egzoz emisyonlarına etkisi
(Gazi Üniversitesi, 2013)Dizel motorları düşük yakıt tüketimlerinden dolayı hem kara hem de deniz taşımacılığında yaygın şekilde kullanılmaktadırlar. Ancak dizel motorlarından kaynaklanan zararlı azot oksit (NOx) ve is emisyonları insan sağlığını ... -
Doğalgaz yakıtlı HCCI bir motorda hidrojen ilavesinin yanma karakteristikleri üzerindeki etkilerinin nümerik olarak incelenmesi
(BİLEŞİM Yayıncılık, 2015)Homojen dolgulu sıkıştırma ile ateşlemeli motorlar konvansiyonel içten yanmalı motorlarla karşılaştırıldığında yüksek termik verim, NOx ve is emisyonlarındaki eş zamanlı azalma avantajlarından dolayı yeni bir araştırma ... -
The Effects of iso-propanol and n-heptane Fuel Blends on HCCI combustion characteristics and engine performance
(2015)In this study, the effects of iso-propanol fuel blends were investigated on HCCI combustion and engine performance. The variations of cylinder pressure, heat release rate, start of combustion and engine performance were ... -
Investigation of usability of the fusel oil in a single cylinder spark ignition engine
(Elsevier B.V., 2015)In order to decrease the dependency on petrol-originated energy resources, the utilization of different energy resources in internal combustion engines has been the center of interest of researchers. The main renewable ... -
An experimental study on the effects of diesel and jet-A1 fuel blends on combustion, engine performance and exhaust emissions in a direct injection diesel engine
(Turkish Society for Thermal Science and Technology, 2016)In this study, an experimental investigation was performed in order to determine the effects of Jet-A1(A100), diesel fuel and Jet-A1/diesel fuel blends (A25, A50, A75) including 25% Jet-A1/75% diesel, 50% Jet-A1/50% diesel ... -
A numerical study on the effects of EGR and spark timing to combustion characteristics and NOx emission of a GDI engine
(Taylor and Francis Inc., 2016)EGR is one of the most significant strategies for reducing especially nitrogen oxides (NOx) emissions from internal combustion engines. The thermal efficiency of spark ignition engines is lower than compression ignition ... -
Combustion and performance characteristics of an HCCI engine utilizing trapped residual gas via reduced valve lift
(Elsevier Ltd, 2016)In this study, the effects of residual gas fraction (RGF) on homogeneous charged compression ignition (HCCI) combustion were investigated experimentally. Experiments were performed at different lambda values and constant ... -
A thermodynamic approach to compare the performance of rhombic-drive and crank-drive mechanisms for a beta-type Stirling engine
(Elsevier Ltd, 2016)In this study, the effect of rhombic drive and crank drive mechanisms on the performance of a beta-type Stirling engine was investigated by nodal analysis. Kinematic and thermodynamic relations for both drive mechanisms ... -
An experimental study on combustion, engine performance and exhaust emissions in a HCCI engine fuelled with diethyl ether-ethanol fuel blends
(Elsevier, 2016)In this study, the effects of diethyl ether–ethanol fuel blends on HCCI combustion, engine performance and exhaust emissions were investigated experimentally in a single cylinder, port injection HCCI engine. In the ... -
