“…Most of the biodiesels produce higher NO [11], lesser brake thermal efficiency (BTE) due to lower oxygen content, lower calorific value and higher specific fuel consumption (SFC) [12], therefore many researchers concentrated to improve the biodiesel efficiency, improve the quality of combustion and emission reduction. Different performance enhancement techniques have been used by different researchers such as oxygenated fuel additives, different compression ratio, injection pressure [13], fumigation [14] and injection timing [15] etc. Some of the researchers concentrated on emission reduction techniques such as exhaust gas recirculation (EGR) [16], water emulsion [17] and selective catalytic converter [18].…”

“…The effects of gasoline fumigation has been experimentally investigated in a single cylinder direct injection diesel engine [27] and reported that the fumigation increases the efficiency and decreases the specific fuel consumption. Fumigation makes effective combustion and reduces the ignition delay [14, 26, 27, 28, 29]. The thermal efficiency increases due to fumigation [29].…”

Many research works are being carried out to enhance the performances of internal combustion engines to meet out the current energy demand and to reduce the emission with the alternate fuels. In this experimental investigation, the performances and emission characteristics of compression ignition engine were studied by using electronic fuel fumigation method. The lemongrass biodiesel blended with 20% of biodiesel and 80% of diesel (B20) was used as primary fuel and 1-propanol is used as secondary fuel for fumigation. The Kirlosker, single cylinder four stroke, direct injection, and water cooled engine was taken for conduction of tests. The speed of the engine is maintained constant and the engine load was varied in the range of 0%–100% and fumigation injection timing is varied in the range of 1 ms, 3 ms and 5 ms to study the engine parameters. It is studied that the brake thermal efficiency of fumigation fuel at 5 ms is 6.7% higher than diesel and at 3 ms is 3.1% higher than the diesel fuel at 100% load. The specific fuel consumption at 5 ms is 16 % higher than the reference diesel fuel. The 5 ms 1-propanol fumigation produces the maximum HC and CO with minimum smoke and NO because of lower combustion temperature and incomplete combustion. The SFC of fumigation fuel at 5 ms is 18.6% higher than diesel at 100% load and 23 % higher than diesel at 80% load. The net heat release of fumigation fuel (1-propanol) at 1 ms produces 2% higher than the reference diesel at crank angle of 360°. The fumigation fuel (1-propanol) injection timing at 5 ms produces more percentage of CO at different load conditions. It is also studied that the minimum level of CO is 0.38 % at 40% load condition. The fumigation fuel at 5 ms injection timing produces minimum percentage of CO 2 at different load conditions. The minimum level of CO 2 is 9.3% at 80% load condition. The other emissions are also analyzed and recorded the levels based on the load condition.

“…Even though the efficiency of internal combustion engine is low [1], the use of diesel engines for vehicle application has expanded since the late 15th century [2]. Not only for transportation, but diesel engines are also widely used in various fields such as agriculture and engineering machinery for its durability and reliability.…”

The use of diesel engines for vehicle applications has expanded for decades. However, it produces black smoke in the form of particulate matter contains fine and invisible particles during operation. The popular method for measuring the smoke opacity is by using a smoke meter for its simplicity and less costly. Fuel injection pressure is one of the parameters that affect the emission significantly, and the proper nozzle adjustment can reduce the density of exhaust gases and improve the engine performance. The purpose of this study is to determine the optimum fuel spray pressure that produces the lowest opacity value and analyse the effect of fuel spray pressure on the opacity value at a different engine speed. The present experiment uses the Hyundai D4BB engine, and the pressure variations were implemented on the injector nozzle at 125, 130, and 135 kg/cm2. The engine was also tested with various engine idle speed, i.e., 1000, 1500, 2000, and 2500 rpm. It has been found that the optimum distance of fuel spraying is 147.679 mm with injector nozzle pressure 130 kg/cm2, and the value of opacity is 9.51%.

ÖZETSunulan çalışmada, Ford XLD 418T tipi turboşarjlı ön yanma odalı bir taşıt dizel motorunda benzin-dizel yakıtı karışımlarının (BDYK'larının) kullanılmasının yanma, motor performans karakteristikleri ve NO x emisyonu üzerindeki etkileri deneysel olarak incelenmiş ve geleneksel dizel yakıtı ile karşılaştırmaları yapılmıştır. Deneyler; tam gazda, farklı motor devirlerinde ve % (2, 4, 6, 8 ve 10) gibi 5 farklı benzin oranında gerçekleştirilmiştir. Çalışma sonunda; benzin oranının artması ile tutuşma gecikmesinin ve açığa çıkan ısı miktarının arttığı görülmüştür. Ayrıca BDYK'ları ile motor performans karakteristiklerinin ve azot oksit (NO x ) emisyonunun iyileştiği ve özellikle orta devirlerde sağlanan iyileşmelerin daha belirgin olduğu belirlenmiştir. Örneğin (2000, 2500 ve 3000) [d/d] gibi motorun orta devirlerinde; özgül yakıt tüketiminde (ÖYT'nde), ortalama olarak % 2,97, % 5,29 ve % 4,11 oranlarında azalma ve bunun sonucunda yakıt maliyetinde ise ortalama % 1,70, % 4,04 ve % 2,86 oranlarında azalma belirlenmiştir. Yine aynı devirlerde efektif güç; % 1,20, % 2,01 ve % 1,92 oranlarında artmıştır. Ayrıca söz konusu devirlerde NO x emisyonununda da ortalama % 10,04, % 10,33 ve % 15,21 oranlarında azalma gözlenmiştir. Böylece söz konusu motorda benzinin % 10'dan düşük oranlarda dizel yakıtına karıştırılarak kullanılmasıyla yanmanın, motor performans karakteristiklerinin iyileştiği ve NO x emisyonunun azaldığı belirlenmiştir.Anahtar Kelimeler: Benzin-dizel yakıtı karışımları, açığa çıkan ısı miktarı, NO x emisyonu, yakıt maliyeti EXPERIMENTAL INVESTIGATION OF THE EFFECTS OF USING GASOLINE-DIESEL FUEL BLENDS ON COMBUSTION, ENGINE PERFORMANCE PARAMETERS AND NO x EMISSION IN A TURBOCHARGED PRE-CHAMBER DIESEL ENGINE ABSTRACTIn the present study, the effects of gasoline-diesel fuel blends (GDFBs) on the combustion, engine performance parameters, and NO x emission have been investigated in a Ford XLD 418 T type turbocharged pre-chamber automobile diesel engine. Experiments have been performed for (2, 4, 6, 8 and 10) % (by vol) gasoline ratios at different engine speeds for 1/1 fuel delivery rate. It is found that ignition delay and heat release rate increase with increasing gasoline ratios. Also, engine performance parameters and NO x emission are improved by using GDFBs and improvement tendency becomes more obvious at moderate speeds. For example; brake specific fuel consumption and fuel cost decrease approximately 2.97 %, 5.29 % and 4.11 % and 1.70 %, 4.04 % and 2.86 % for all of the gasoline ratios at (2000, 2500 and 3000) rpms, respectively. Effective power increases at the levels of 1.20 %, 2.01 % and 1.92 % and NO x emission decreases approximately 10.04 %, 10.33 % ve 15.21 % for all of the gasoline ratios at (2000, 2500 and 3000) rpms, respectively. As a result, combustion, engine performance parameters and NO x emission of this engine have been improved by using (2-10) % GDFBs.
