LITURATURE REVIEW ON EFFECT OF OXYGENATED ADDITIVES ON S.I. ENGINE PERFORMANCE & EMISSIONS
The Petrol engines provide the major power source for the transportation needs of the mankind. However the emission from the engines threatens the environment seriously and they are considered as the major source of the air pollution. They are confirmed to cause the environmental problems like Global Warming, Greenhouse gases and the acid rain. The addition of an oxygenating agent into fuel oil is one of the possible approaches for reducing this problem because of the obvious fuel oil constituent influences on engine emission characteristics. This paper reviews the available oxygenated additives and compares their effect on exhaust gas emission with help of conference papers and journals. During study of available material, it is found that oxygenated additives are an effective method for reducing PM, CO and HC without significant increase in the NOx emission.The objective of the present paper is to investigate the effect of these oxygenated additives on spark ignition engine performance and emission characteristics at variable engine speed operating conditions.

Fossil fuels play a crucial role in the world energy market. The world's energy market worth around 1.5 trillion dollars is still dominated by fossil fuels. The World Energy Outlook (WEO) claims that energy generated from fossil fuels will remain the major source and is still expected to meet about 84% of energy demand in 2030. As population increases and the standard of living improve, there will be a shortage of source of energy. Bio-fuel such as bio-diesel and bio-ethanol are now receiving the impetus required for becoming the fuel source for the future. One of the way to reduced the dependence on the fossil fuel is the blending of bio-ethanol with the conventional diesel. Advances in technology have allowed development of alternative energy sources. In this review paper we briefly discuss replacement of fossil fuel with bio-diesel+ bio-ethanol+ diesel and its effect on the engine performance and emission characteristics.
Effect of oxygenated fuel additive on diesel engine performance and emission: A review
This Improvement of fuel properties essential for suppression of pollutant and optimization of engine performance. One way is use of additives. Oxygenated additives were conventionally recommended for gasoline. But now day’s oxygenated additives are widely considered for diesel fuel also. This paper reviews the available oxygenated additives and compares their effect on exhaust gas emission with help of conference papers and journals. During study of available material It is found that , oxygenated are effective method for reducing PM, CO and HC without significant increase in the NOx emission.
Understanding the Effect of Oxygenated Additives on Combustion Characteristics of Gasoline
Journal of Energy Resources Technology
Laminar burning speed and ignition delay time behavior of iso-octane at the presence of two different biofuels, ethanol and 2,5 dimethyl furan (DMF), was studied in this work. Biofuels are considered as a better alternative source of fossil fuels. There is a potentiality that combustion characteristics of iso-octane can be improved using biofuels as an oxygenated additive. In this study, three different blending ratios of 5%, 25%, and 50% of ethanol/iso-octane and DMF/iso-octane were investigated. For laminar burning speed calculation, equivalence ratio of 0.6–1.4 was considered. Ignition delay time was measured under temperature ranges from 650 K to 1100 K. Two different mechanisms were considered in numerical calculation. These mechanisms were validated by comparing the results of pure fuels with wide range of experimental and numerical data. The characteristic change of iso-octane with the presence of additives was observed by comparing the results with pure fuel. Significant cha...

Intensive attention is required to see this problem. In this review paper there is a comparative study to find out the alternative for diesel fuel and efforts to increase its performance. In this paper blending of oxygenated additive at different percentage with sole diesel and effects on various performance parameters are studied. Blending of Oxygenated additives, improve brake specific fuel consumption (BSFC), combustion performance and reduce emission from diesel engine. Properties of the blended fuel and standard exhaust emission of compression ignition (CI) engine have been studied comparatively for sole diesel, NM-Diesel and NE-Diesel fuel blends from different experimental investigation on engine performance and exhaust gas emissions at various engine operating conditions using an engine dynamometer setup.

The demand for renewable energy sources is gradually escalating due to the spontaneously growing population and global economic development. The access to fossil fuels is gradually declining due to the limited available reserves. Hence, renewable energy resources, technology choice, and energy policy are always being revised due to the modernization of society. Meanwhile, the liquid energy sources such as methyl ester from locally produced vegetable oils are readily accepted by many countries globally, although it is currently being blended (up to 20%) with diesel. Oxides of nitrogen are the most substantial emissions from diesel engines produced due to high combustion temperature. The addition of alcohol in the fuel reduces the NO x formation since alcohols have high latent heat of evaporation. The present study's primary purpose is to investigate the effect of different alcohol types on engine performance and emission characteristics. For this purpose, seven test fuels and neat diesel were used. The test fuels P20 (20% palm biodiesel with 70% neat diesel and 10% alcohol on a volume basis)
This paper present the experimental investigation on effect of oxygenated additives on multi-cylinder Diesel engine performance and emission. The experimental trail was carried out at constant speed of 1500rpm with variable load conditions and 10% of oxygenated additive in diesel fuel. Six different additives were selected for investigation. After the experimentation, it’s found that DIGILYME shows least brake specific fuel consumption of all other additives but around 10 -20% higher than that of diesel for the same load variation. All additive shows rise in EGT except DMC which is quite close to that of diesel. Brake thermal efficiency of DMC is high at idle to moderate load after that it drop than that of diesel due to low calorific value. It shows around15% rise in low load condition. DMC looks very promising in emission control. DMC shows around 15-30 drop in CO high load condition while 20 % drop in HC. Also It is good option in NOx control as it shows around 10% drop at low load and 15% drop at higher load condition. The only limitation is high smoke production by DMC where other additive like N Butyl Alcohol help in lowering smoke production that is its show around 30% drop at high load condition.
Application of additives with gasoline fuel: A review
E3S Web of Conferences, 2020
Alternative fuels have become very important nowadays and proving their importance in both positive ignition engines and compression ignition engines, so as to reduce the consumption of gasoline and diesel respectively. Also, blending of these alternative fuels (additives) into gasoline has been proved important in improving various performance parameters and reducing emission parameters. Various studies have been carried out in the field of using additives in gasoline to see the effects on performance parameters like Brake power, Brake thermal efficiency, Volumetric efficiency and brake specific fuel consumption. Also, this study emphasizes reducing the emissions to the ambient. The aim of this review is to compare and study various additives which can be blended with gasoline and study their effect on performance and emission characteristics of Spark ignition engines.
