This document summarizes research on the performance analysis of emissions using bio-diesels as fuel in diesel engines with different compression ratios. It discusses how smoke, NOx, CO, brake specific fuel consumption, brake thermal efficiency, and exhaust gas temperature are affected by varying the compression ratio when using blends of jatropha and mahua oils compared to diesel fuel. The document also reviews literature on using vegetable oils as fuels in diesel engines and the process of biodiesel production through transesterification. Experimental results show that bio-diesel blends produce lower emissions of CO, HC and higher emissions of CO2 and O2 compared to diesel fuel due to the oxygen content of bio-diesels.
Evaluation of Biodiesel as an Alternate Fuel to Compression Ignition Engine a...IJMER
To meet increasing energy requirements, there has been growing interest in alternate fuels like biodiesel to provide a suitable diesel oil substitute for internal combustion engines. Biodiesel offer a very promising alternate to diesel oil since they are renewable and have similar properties. Further it can be used with/without any modifications to the engine. It is an oxygenated fuel and emissions of carbon monoxide are less unlike fossil fuels, the use of biodiesel does not contribute to global warming as CO2 emitted is once again absorbed by the plants grown for vegetable oil/biodiesel production, thus CO2 balance is maintained. In the present work the Honge and Jatropha Curcas oil (Biodiesel) at various blends is used with pure diesel to study its effect on performance and emission characteristics of the engine. The performance of the engine under different operating conditions and blends are compared by calculating the brake thermal efficiency and brake specific fuel consumption by using pure diesel and adding various blends of Honge and Jatropha Curcas oil to diesel. The exhaust gas analyzers and smoke meters are used to find the percentage of carbon monoxide (CO), carbon dioxide (CO2), Hydrocarbons (HC) and oxides of nitrogen (NOx) emissions.

OPTIMIZATION OF BIODIESEL FROM ARGEMONE OIL WITH DIFFERENT REACTION PARAMETE...Er Sandeep Duran
This experiment work is to investigate the performance parameters of single cylinder, four stroke engine connected to eddy current dynamometer fuelled with argemone biodiesel and blend with diesel fuel under different load condition (0%, 20%, 40%, 60%, 80%, 100%) and constant engine running speed. The performance parameters consist of brake power (BP), brake thermal
efficiency (BTHE), and brake specific fuel consumption (BSFC). The argemone mexicana oil was used for production of biodiesel. The transesterification process was used for production of argemone oil methyl ester by using methanol in the presence of sodium metal as a catalyst. The process undergoing various reaction conditions with molar ratio (1:6, 1:3, 1:9 oil to methanol), reaction time (60 min, 90 min, 120 min), reaction temperature (55°C, 65°C, 75°C, 85°C) and catalyst (1%, 1.5%, 2%, 2.5% w/w of oil) effects the fuel properties of argemone biodiesel.

Biodiesel is an attracted alternative fuel and biodiesel“diesel blends can be used as fuel in order to substitute some part of diesel in engine at various applications. In this study, the spray properties of different type of blends of biodiesel“diesel (25%, 50%, 75% and 100% biodiesel) as well as pure diesel is investigated under various ambient conditions by means of high-speed schlieren photography technique. A comparative analysis of blended fuels and diesel sprays is also presented. The experimental results show that when adopting fuel blends with variable biodiesel“diesel fractions in the swirl-type injector sprays, the spray developing patterns are not significantly changed. In the case of low ambient pressure (surrounding condition), the main spray tip penetration decreases and the spray angle increases with the increase of biodiesel fraction. Under the elevated ambient pressure condition, the difference of spray penetration amongst the blends shows inconspicuous, meanwhile the spray angle of all test fuels keeps almost constant in the fully developed stage except that the spray of pure diesel shows a larger cone angle in the beginning of injection period.

The indiscriminate usage of fossil fuels in many
countries has led to an increased interest in the search for
suitable alternative fuels. Methyl Esters of Vegetable oils and
Animal fats are found to be good alternative, renewable and
environmental friendly fuels for C.I. engines.
This paper presents the results of investigation carried
out in studying the properties and behavior of methyl esters
of corn seed oil, fish oil and its blends with diesel fuel in a C
I Engine. Engine tests have been carried out to determine the
performance, emission and combustion characteristics of the
above mentioned fuels.
The tests have been carried out in a 4-stroke,
computerized, single cylinder, constant speed, direct injection
diesel engine at different loads. The loads were varied from
0% to 100% of the maximum load in steps of 25%. The Methyl
Ester blends of 10%, 20% and 30% by volume with diesel were
used. The engine test parameters were recorded with the help
of engine analysis software and were studied with the help of
graphs.
The results showed that the properties of the above mentioned
oils are comparable with conventional diesel. The 20% blend
performed well in running a diesel engine at a constant speed
of 1500 rpm. It substantially reduced the emissions with
acceptable efficiency. Hence the oils can be used as suitable
additives for diesel in compression ignition engine.
A Comparative Analysis of Compression Ignition Engine Characteristics Using P...Editor IJMTER
This paper investigate the scope of utilizing biodiesel with high bland (B20 & B40)
developed from the Methyle alcohol from pongamia oils as an alternative diesel fuel. The major
problem of using neat pongamia oil as a fuel in a compression ignition engine arises due to its very
high viscosity. Transesterification with alcohols reduces the viscosity of the oil and other properties
have been evaluated to be comparable with those of diesel. In the present project work, an
experimental investigation is carried out on performance and emission characteristics of preheated
higher blends of pongamia biodiesel with diesel. The higher blends of fuel is preheated at 60, 75, 90
and 110˚C temperature using waste exhaust gas heat in a shell and tube heat exchanger.
Transesterification process is used to produce biodiesel required for the project from raw pongamia
oil. Experiments were done using B20 and B40 biodiesel blends at different preheating temperature
and for different loading. A significant improvement in performance and emission characteristics of
preheated B40 blend was obtained. B40 blend preheated to 110˚C showed maximum 8.72% and
8.97% increase in brake thermal efficiency over diesel and B20 blend respectively at 75% load. Also
the highest reduction in UBHC emission and smoke opacity values are obtained as 79.41% and
80.6% respectively over diesel and 78.12% and 73.54% respectively over B20 blend for B40 blend
preheated to 110˚C at 75% load. Thus preheating of higher blends of diesel and biodiesel at higher
temperature improves the viscosity and other properties sharply and improves the performance and
emission.

Use of Jatropha Biodiesel in C.I. Engines- A reviewIJERA Editor
Petroleum based fuels play a vital role in rapid depletion of conventional energy sources. Along with their
increasing demands, these are also major contributors of air pollution which is contributing to greenhouse effect
and consequently to ozone layer depletion.
Major portion of today’s energy demand in India is being met with fossil fuels. Hence, it is high time that
alternative fuels for engines should be derived from different indigenous sources. As India is an agricultural
country, there is a wide scope for the production of vegetable oils (both edible and non-edible) from different oil
seeds.
This paper is based on recommending an alternate fuel for diesel engines. Expectations have been high for the
production of biodiesel from the Jatropha oil-crop. Jatropha is promoted as a drought and pest resistant crop,
with the potential to grow on degraded soils with a low amount of inputs. These characteristics encourage hope
for positive environmental and socio-economic impacts from Jatropha biodiesel.
Ijaems apr-2016-2 Experimental Parametric Study of Biodiesel to Develop Econo...INFOGAIN PUBLICATION
In this globalization realm, there in constant growth in the rate of expenditure of fossil fuels, consequent on ever increasing population and urbanization. This gives charge to depletion of finite resources in the near future. Fossil fuel emission causes global-warming also green-house gases are intangible factor which collectively degrading the planet. As such, the situation demands for an alternate source of energy that can be used to overcome the conjectured energy crisis. In contrast to this, if the energy source is clean and renewable, it will reduce the environmental trouble as well. In the quest an alternate and renewable energy resources, scientists have plead with a variety of options among which biodiesel-diesel blends as alternative fuels has become a popular option and is getting the attention of many researchers. This is because scientists have enlist the properties of biodiesel prepared from vegetable oils are very close to commercial diesel and thus it has a promising future as an alternative fuel for diesel engine. Biodiesel being renewable, biodegradable and green fuel can reduce our dependence on conventional/non-renewable fossil fuels and it also helps to keep pure quality of air by reducing obnoxious automotive/vehicular emissions. Possible solution of this problem is to replace or find renewable and economically feasible fuel as an alternative source. Already a lot of work for source which fulfill the criteria of sustainability and economical carried out. But the effluent is critical issues. So characterization and formation of biodiesel with zero effluent is prime objective.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
