“…By adding 300, 200 and 100 ppm of TiO 2 nanoparticle to MOBD resulted in 3.6%, 2.4% and 1.8% decrease in HC emission, respectively, at full load compared to neat MOBD. This result is in line with other research (Venu and Madhavan 2016;Yuvarajan and Munuswamy 2016c;Sadhik Basha 2014). Figure 4 shows the variation in CO emission with load for diesel, MOBD, MOBDT100, MOBDT200 and MOBDT300.…”

“…HC emissions for MOBDT100, MOBDT200 and MOBDT300 are lower than that of MOBD. TiO 2 nano-fluids present in the fuel improve the rate of combustion by providing additional oxygen molecules and result in improved combustion (Venu and Madhavan 2016). Reduction in HC emission was more significant for MOBDT300.…”

“…Reduction in HC emission was more significant for MOBDT300. This is due to secondary atomization of MOBD with considerable fuel distribution in the combustion chamber with higher content of TiO 2 nanoparticles (Venu and Madhavan 2016). In addition, the oxygen content in the fuel increases with increase in TiO 2 nanoparticles causing improved combustion (Arulprakasajothi et al 2015).…”

“…The water present in MOBDT100, MOBDT200 and MOBDT300 reduces the peak temperature during combustion by absorbing the heat during combustion (Sadhik Basha 2014;Keskin et al 2008). TiO 2 nano-fluids increase the effective surface area of fuel with air and result in improved combustion and lower NO x emissions (Venu and Madhavan 2016). …”

Biodiesel obtained from mustard seed is found to be a promising alternative for petroleum diesel fuel owing to its similarity in physical and chemical properties. In this work, TiO 2 nano-fluid which acts as an oxygen buffer during combustion was added to mustard oil biodiesel (MOBD) to study its effect on emission characteristics of MOBD. TiO 2 nano-fluid can provide high surface energy during the course of combustion and reduces the limitations of neat biodiesel. A four-stroke, multi-cylinder, water-cooled, diesel engine was used in the experiments and was fueled with diesel, neat MOBD and MOBD with TiO 2 nanoparticles at 100 ppm (MOBDT100), 200 ppm (MOBDT200) and 300 ppm (MOBDT300). Experimental results revealed that the TiO 2 nanoparticles had positive effect on the emission characteristics of MOBD as it acted as an oxidation buffer. MOBDT300 showed a reduction in HC, CO and smoke emissions as compared to pure MOBD. In addition, NO x emissions were also reduced by the catalytic activity of the TiO 2 nanoparticles which reduce the peak combustion temperature. Therefore, TiO 2 nano-fluid had a positive effect on reducing the emissions associated with neat biodiesel.

This study was compiled from the results of various researches performed on using diethyl ether as a fuel or fuel additive in diesel engines. Three different techniques are used the reduction of the harmful exhaust emissions of diesel engines. The first technique for the reduction of harmful emissions is improved 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 final technique to reduce emissions and also improve diesel engine performance is the use of various alternative fuels or fuel additives. The major pollutants of diesel engines are oxides 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 is the use of various alternative fuels i. e. natural gas, biogas, biodiesel or using the additives with alternative fuels or conventional diesel fuel. Therefore, it is very important that the results of various studies on alternative fuels or fuel additives are evaluated together to practice applications. Especially, this study focus on the use diethyl ether in diesel engines as fuel or fuel additive in various diesel engine fuels. This review study investigates the effects of diethyl ether addition on the fuel properties and performance characteristics.

Biodiesel has emerged as a promising renewable fuel, which can help reduce dependency on fossil fuel and has potentiality to replace petrodiesel partially. Usage of biodiesel results in decreased carbon monoxide, hydrocarbon, and particulate matter emission. However, it has some drawbacks such as increased nitrogen oxides (NOx) emission, lower calorific value, and poor engine performance, which restrict wide usage of biodiesel as a potential substitute in compression ignition engine. There is a scope to overcome these problems by applying metal based nanoparticles (NPs) as fuel additive. This article reviews the preparation and stability of nanofluid and the effect of metal based NPs on fuel properties, combustion, performance, and emission characteristics. It has been concluded that inclusion of nanoadditives increases cetane number and calorific value of blended fuel. According to the most authors, metal based NP doped biodiesel blend enhances ignition characteristics, improves engine performance, and reduces emissions including NOx compared to biodiesel blend without additive. However, some concerns and challenges identified in this article need to be addressed to make this technology feasible for commercial application in near future.
