“…The decline in BSFC was ascribed to the favorable effect of nanoparticles on the fuel physical properties and the reduction of ignition delay. Venkatesan 6 and Aalam et al 23 noted the enhancement in the combustion efficiency and thus less amount of fuel is necessary for the specific power output. Alumina nanoparticles oxidize the carbon deposits leading to the fuel consumption reduction owing to the catalytic effect, surface area to volume ratio enhancement, and the combustion characteristics improvement.…”

“…The lower produced CO emissions when nanoparticles blended to pure diesel were due to the uniform dispersion and complete combustion of nanoparticles. 14,23,25 At full load, the average reductions in CO emissions were 4.5%, 15%, and 25% at aluminum oxide nanoparticles of 20, 30, and 40 ppm doses, respectively compared to diesel fuel. cylinder temperatures.…”

Experimental work was done to examine the impact of diesel fuel with alumina nanoparticles on combustion characteristics, emissions and performance of diesel engine. Alumina nanoparticles were mixed with crude diesel in various weight fractions of 20, 30, and 40 mg/L. The engine tests showed that nano alumina addition of 40 ppm to pure diesel led to thermal efficiency enhancement up to 5.5% related to the pure diesel fuel. The average specific fuel consumption decrease about neat diesel fuel was found to be 3.5%, 4.5%, and 5.5% at dosing levels of 20, 30, and 40 ppm, respectively at full load. Emissions of smoke, HC, CO, and NOX were found to get diminished by about 17%, 25%, 30%, and 33%, respectively with 40 ppm nano-additive about diesel operation. The smaller size of nanoparticles produce fuel stability enhancement and prevents the fuel atomization problems and the clogging in fuel injectors. The increase of alumina nanoparticle percentage in diesel fuel produced the increases in cylinder pressure, cylinder temperature, heat release rate but the decreases in ignition delay and combustion duration were shown. The concentration of 40 ppm alumina nanoparticle is recommended for achieving the optimum improvements in the engine’s combustion, performance and emission characteristics.

ÖzetBu çalışma; dizel, biyodizel, su içeren emülsiyon yakıtları ve çeşitli yakıt karışımları gibi dizel motor yakıtlarında nano materyal içerikli katkıların kullanılmasının motor performansı ve emisyonlara etkileri üzerine yapılmış çeşitli çalışmaların sonuçlarından derlenmiştir. Dizel motorlarda zararlı egzoz emisyonlarını azaltması için üç farklı teknik uygulanmaktadır. Zararlı emisyonları azaltmak için uygulanan tekniklerden ilki motor tasarımda ve yakıt püskürtme sisteminde değişiklikler yapılarak yanmanın iyileştirilmesidir. Ancak bu pahalı ve zaman alıcı bir süreçtir. İkinci teknik katalitik konvertör ve partikül filtresi gibi çeşitli egzoz gazı azaltıcı sistemler kullanmaktır. Ancak, bu sistemler dizel motorun performansını olumsuz yönde etkiler. Dizel motorlarda, emisyonları azaltmak ve aynı zamanda dizel motorun performansını artırmak için kullanılan üçüncü teknik ise çeşitli yakıt katkılarının kullanılmasıdır. Dizel motorlardan yayılan en önemli kirleticiler azot oksit (NOx) ve partikül madde (PM−is) emisyonlarıdır. Uygulamada, NOx ve PM emisyonlarını birlikte azaltmak oldukça zordur. Emisyonları azaltmanın ve motor performansını artırmanın en iyi yolunun nano materyal içerikli katkıların ve suyla emülsiyonlaştırılmış yakıtların kullanımı olduğu birçok araştırmacı tarafından bildirilmektedir. Bu derlemede çeşitli dizel motor yakıtlarında farklı nano materyal içerikli katkıların kullanımının yakıt özellikleri ve motor performansına etkileri incelenmiştir.

AbstractThis study compiled the results of various researches performed on the effects of performance and emissions of diesel engine using nanomaterials additives in diesel engine fuels such as diesel, biodiesel, water emulsified fuels and various fuel blends. Three different techniques are used in reduction of the harmful exhaust emissions of the diesel engine. The first technique for the reduction of harmful emissions is improving the combustion by modification of engine design and fuel injection system, but this process is expensive and time consuming. The second technique is the using various exhaust gas devices like catalytic converter and diesel particulate filter. However, the use of these devices affects negatively diesel engine performance. The other technique to reduce emissions and also improve diesel engine performance is the use of various fuel additives. The major pollutants of diesel engine are oxide of nitrogen (NOx) and particulate matter (PM). It is very difficult to reduce NOx and PM simultaneously in practice. The most researches declare that the best way to reduce the emissions and increase the engine performance is the use of nano material additives and water emulsified fuels. The effects of using different nano material additives in various diesel engine fuels on the fuel properties and engine performance were investigated in this review.

In this study, the performance, emission and combustion characteristics of two different biodiesel blends produced from Mahua and pongamia methyl esters were compared with conventional diesel fuel. Methyl esters for experiment were produced by using a catalytic transesterification process and, compared the properties with ASTM standard values of biodiesel fuel and diesel fuel. The experiments were performed in a four stroke, single cylinder, common rail direct injection (CRDI) system assisted diesel engine at a constant speed of 1500rpm with varying injection pressure. During the tests, the specific fuel consumption, brake thermal efficiency, combustion and exhaust emissions of the CRDI diesel engine were measured. From the results it is clear that the HC, CO and smoke levels are drastically reduced when using the methyl ester blends. Especially in the case of MME20, NOx emissions was minimum when compared with other blends and it also found less amount of other harmful emissions like HC, CO and smoke.
