Review of Performance and Emission Analysis of Biodiesel Blends an Promising Alternative Fuel
Biodiesel is defined as the mono alkyl esters of long chain fatty acids derived from renewable lipid sources. It is a term used to describe a methyl or ethyl ester made from vegetable oils, animal fats, and used cooking oils and fats. It is oxygenated, non-toxic, sulphur-free, biodegradable and renewable fuel. The scarcity and increase in the crude oil prices have forced everyone to think on the use of biodiesel as an alternative fuel source. Also, it is important that unlike the traditional fuels which emit greenhouse gases and particulate matter, the biodiesel is greener and hence less polluting. More than 350 oil-bearing crops identified, among which some only considered as potential alternative fuels for diesel engines. The focus of this study is to review the effect of using biodiesel blends on engine performance and exhaust emissions in a CI engine.

Alternate fuels should be economically attractive in order to compete with currently used fossil fuels. Biodiesel, produce by the transesterification of vegetable oils or animal fats with simple alcohols and catalyst attracts more and more attention recently. Biodiesel is clean burning diesel alternative and has many attractive features including renewability, biodegradability, non toxicity and low emission. The aim of the present review is to study the biodiesel production from transesterification process, effect of reaction parameters on conversion of biodiesel yield and its combustion, performance and emission characteristics. It observes that the base catalysts are more effective than acid catalysts. Biodiesel is a notable alternative to the widely used petroleum-derived diesel fuel since it can be generated by domestic and non domestic sources such as soybeans, coconuts, rapeseeds, Jatropha, Karanja, rubber seed, Mahuaa, waste frying oil, etc. and thus these reduces dependence on diminishing petroleum fuel from foreign sources. The problems with substituting triglycerides for diesel fuels are mostly associated with their low volatilities, high viscosities and polyunsaturated character. The main purpose of the transesterification process is to lower the viscosity of the oil. Over a number of years, the work of exploring different biodiesel as an alternative to diesel fuel has been carried out worldwide. The performance of biodiesel is closed to petroleum diesel fuel. The brake power of biodiesel fuel is approximately equal to diesel, while the specific fuel consumption is higher than that of diesel. The combustion characteristic of biodiesel fuels is similar to petroleum diesel fuel and blends provide small ignition delay, higher ignition pressure, and higher ignition temperature and peak heat release. The emission from the biodiesel is comparatively less to diesel except NO x .
The Study of Different Biodiesel Production from Various Resources and Its Properties -An Overview
Biodiesel is a renewable resource of energy, which helps to reduce the dependence on the limited economy resources available in the world. The present research work is an approach towards attaining price competency of biodiesel to petroleum diesel. Biodiesel either directly or blended with diesel fuel is widely investigated to reduce the depletion of fossil fuels and environmental degradation. There has been growing interest in alternative fuels like biodiesel, a best substitute fuel for internal combustion engines. This paper reviews the biodiesel from various resources, different methodologies used for biodiesel production and the properties of different biodiesel. Biodiesel is an eco-friendly, alternative diesel fuel produced from vegetable oils and animal fats. Biodiesel can be used as a fuel for vehicles in its pure form, but it is usually used as a blended fuel (Diesel and Biodiesel) to reduce levels of particulates, carbon monoxide and hydrocarbons from diesel-powered vehicles. The main objective of this study is the development of biodiesel by various methods and fuel-related properties.
Analysis of Fuel Properties and Emission Behaviour of Biodiesel
About all the countries are facing the economy problem during the paucity of petroleum and almost all petroleum demand through imports. A Substitute for Diesel engine fuel is of huge consequence to the Fuel scarcity. In this study Experiments were carried out in the diesel engine by using water melon seed oil and Blended watermelon seed oil. Three blends of watermelon oil such as 25%, 50%, 75% and 100% are used in this experimentation. The Blended oil is heated externally up to boiling temperature 67 o C before injecting into the test cylinder. Engine performance is very high at the same time lowest specific fuel consumption were attained while using the Blended fuel. The experimental results are discussed the oil content of Water melon seed oil remarkably high. Lesser NOX where induced while in 100 % of bio diesel used in the engine and very stumpy Carbon dioxide (CO) where induced while the engine operates at maximum load. Comparatively the blended fuel significantly improves the Engine performance and Break thermal efficiency to the other Blended fuels. Hence the Blended Fuel is Very suitable to the Diesel Engine to operate the engine at utmost consignment.
A Review on Performance of Diesel Engines by using Biodiesel blends from Different oils
The expanding industrialization and mechanization of the world has led to a steep rise for the demand of petroleum products. Petroleum based fuels are obtained from limited reserves. Therefore biodiesels are alternatives to replace in the place of fossil fuels. Vegetable oils display an exceptionally encouraging condition of working as option energizes to conventional diesel fuel. The properties and characteristics of biodiesels can be contrasted positively for the qualities required for the compression ignition engine fuels .At present several countries does not containing petroleum resources are facing a severe fuel crisis, mainly due to the import of raw oil. Therefore, it is very emergency to look for alternative fuels, which can be extracted from resources available in the countries. The vegetable oils releases less emissions than conventional fuels. This paper reviews the Performance by using biodiesel blends from different oils jatropha, Pongamia, Mahua, animal fat, Cottonseed oil, soybean, crude oil, rapeseed oil, palm oil, waste cooking oil, sunflower, neem oil, etc. along with the experimental work carried out in several countries in this area.

There are concerns that biodiesel feedstock may compete with food supply in the long term, if the raw materials are vegetable virgin oils only. Therefore, throughout the world, large amounts of non-edible oil plants are available in nature. In this paper, experimental study has been carried out to analyze engine performance and emission characteristics for direct injection diesel engine using biodiesel obtained from non-edible oil such as jatropha oil and was blended with diesel fuel (DF) by 5% (JB5), 10% (JB10), 15% (JB15) and 20% (JB20) volumetrically without any engine modifications. Due to the presence of molecular oxygen, biodiesel undergoes improved combustion in the engine and has less polluting emissions in comparison with normal diesel fuels. Engine performance test was performed at 100% load keeping throttle 100% wide open with variable speeds of 1500 to 2400 rpm at an interval of 100 rpm. Whereas, emission tests were carried out at 2300 rpm at 100% and 80% throttle position. As results of investigations, there has been a decrease in torque and brake power, while increase in specific fuel consumption (sfc) has been observed for all biodiesel blend fuels over the entire speed range compared to DF. In case of engine exhaust gas emissions, reduction in HC, CO and CO2 were found for all blends. Besides, sound level for blend fuels was also reduced compared to DF. It can be concluded that jatropha biodiesel blend fuels can be used in diesel engines without any engine modifications and have beneficial effects both in terms of emission reductions and alternative petroleum diesel fuel. © 2012 Praise Worthy Prize S.r.l. - All rights reserved. http://umexpert.um.edu.my/file/publication/00003184\_86855.pdf
Overview properties of biodiesel diesel blends from edible and non-edible feedstock
Biodiesel is biodegradable and nontoxic alternative fuel for diesel engine which has become more attractive to replace diesel fuel. In this study, vegetable oil was identified as potential sources for biodiesel production. The production of biodiesel from different non-edible oilseed crops has been extensively investigated for the past few years. Thus, the aim of this study is to critically review on the characteristic of the potential biodiesel and biodiesel diesel blends fuel properties. The aspects of this study cover the biodiesel production and fuel properties of biodiesel and biodiesel blends. Besides, some studies have shown that there is a direct correlation between fatty acid composition and biodiesel properties. The fuel properties of biodiesel blends fuel were very close to diesel fuels and satisfied ASTM 6751 and EN 14214 standards. As a final note, further study on the utilization of biodiesel blends needs to be carried out in order to ensure optimization in engine operation.
STUDY OF BIODIESEL BLENDS AND EMISSION CHARACTERISTICS OF BIODIESEL
International Journal of Innovative Research in Science, Engineering and Technology, 2013
Biodiesel is a renewable diesel replacement fuel that is manufactured from domestically produced oils such as soybean oil, recycled cooking oils, or animal fats [13]. To manufacture biodiesel, these fats and oils are chemically reacted with a short chain alcohol (such as methanol) and a catalyst to produce biodiesel and a glycerin co-product. Biodiesel can be used alone (B100) or blended with petroleum diesel in any proportion [13]. Biodiesel can be legally blended with petroleum diesel in any percentage. ASTM International develops specifications for conventional diesel fuel (ASTM D975). These specifications allow for biodiesel concentrations of up to 5% (B5). Low-level biodiesel blends, such as B5 are ASTM approved for safe operation in any compression-ignition engine designed to be operated on petroleum diesel. Biodiesel can be blended and used in many different concentrations, including B100 (pure biodiesel), B20 (20% biodiesel, 80% petroleum diesel), B5 (5% biodiesel, 95% petroleum diesel) and B2 (2% biodiesel, 98% petroleum diesel) [14]. This paper deal with the different reviews of the studies associated with the emissions properties of biodiesel. Various Studies showed pollutants like CO (Carbon monoxide), HC (Hydro Carbon), PM (Particulate matters) etc. can be reduced by using biodiesel blended with diesel. Increment in NOx emission has been a problem in biodiesel but it can be overcome by various methods like cetane no improver. Additives play a crucial role in minimizing NOx emission that could be a sigh of relief for the researcher who are opting biodiesel as an alternative fuel [28].

As a renewable, sustainable and alternative fuel for compression ignition engine, biodiesel instead of diesel has been increasingly fuelled to study its effects on engine performances and emissions in the recent 15 years. Biodiesel is an alternative to petroleum-based fuels derived from vegetable oils, animal fats, and used waste cooking oil including triglycerides. Bio-diesel production is a very modern and technological area for researchers due to the relevance that it is winning everyday because of the increase in the petroleum price and the environmental advantages. Trans esterification is the most common method and leads to monoalkyl esters of vegetable oils and fats, now called bio-diesel when used for fuel purposes. In spite of having some other applications, recently it is being considered as one of the most promising alternative fuels in internal combustion engine. Also on the other hand increasing stringent emission regulation will make the use diesel very difficult in the coming days. Regarding the health and environment there is an alternate of diesel called biodiesel. This review paper collects experimentally investigated records and results of engine performance & emission characteristics of compression engine with biodiesel and compared it with conventional diesel. From the review it is found that the use of biodiesel leads to the substantial reduction in PM, HC and CO emissions accompanying with the imperceptible power loss, the increase in fuel consumption and the increase in NOx emission on conventional diesel engine.
