Zinc oxide nanotubes and nanoflowers are synthesized using urea as template through hydrothermal technique. XRD confirmed that product is consists of zinc and oxygen atoms forming a hexagonal crystal system with ZnO chemical formula. SEM showed that tubes and flower like particles are formed. ATR‐IR confirmed the presence of Zn−O bond as a functional group. UV‐VIS spectroscopic analysis exhibits that product has a band gap energy of 3.49 eV. Synthesized product due to its outstanding properties such as wide band gap semiconductor and large surface area to volume ratio is used as a catalyst for individual and simultaneous catalytic degradation of methylene blue (MB) and Congo red (CR) dyes. The apparent rate constant (kapp) value of individual and simultaneous catalytic degradation of CR dye is decreased with increase in catalyst dosage while kapp value of individual and simultaneous catalytic degradation of MB dye is increased with increase in catalyst dosage. The synthesized product is found more active towards CR dye as compared to MB dye. Small size and high surface area to volume ratio of product also make it a desirable additive for enhancing the efficiency of diesel fuel. Results obtained from fuel additive activity show that as the concentration of nanoadditive is increased from 20, 40, 60, 80 and 100 ppm the calorific value is increased which indicates the enhanced efficiency of fuel due to additive.

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. Anahtar kelimeler: Dizel motor performansı, biyodizel, emülsiyon yakıt, nano materyal katkılar. * İsmet SEZER, isezer@gumushane.edu.tr, https://orcid.org/0000-0001-7342-9172 569 SEZER İ. 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.

Summary Biodiesel obtained from inedible sources emerged as a productive approach in Indian energy scenario due to the scarcity of food resources come up with extensive usage of edible crops. Kusum (Schleichera oleosa) oil is abundantly available in India and can be used as feedstock to produce biodiesel. However, issues such as higher viscosity, poor stability, and lower calorific value result in poor ignition characteristics, hence limiting its use in combustion applications. An improvement in performance and emission characteristics can be achieved by doping nanoparticles in Kusum biodiesel (KBD). The present work examines the impact of a metal compound and carbon‐primarily based nanoparticles on the evaporation time and ignition probability of the KBD. During the experimental process, different fuel samples of KBD were prepared by amalgamating nanoparticles; then, a sequence of hot plate (stainless steel) ignition test was conducted on these test fuels. The comparative assessment of neat biodiesel and the biodiesel fuel doped with 30 ppm each of alumina (Al2O3), and multiwalled carbon nanotubes (MWCNTs) nanoparticles were carried out. The Kusum oil was converted to biodiesel using two‐stage transesterification process. In the initial stage, refined oil was gone through the acid catalyst esterification process followed by the transesterification reaction. The prepared methyl ester was confirmed and characterized using GC‐MS technique. The thermophysical and spray properties of the test fuels including density, viscosity, calorific value, cloud/pour point, Sauter mean diameter (SMD), and specific surface area (SSA) were also calculated. The experimental result showed a significant increase in ignition probability and heat conduction properties due to improved surface area/volume ratio. Also, lower evaporation time was noted for metal/carbon‐based nanoparticles doped biodiesel as compared with neat biodiesel.
