Biodiesel can be made from vegetable oils, animal fats, or recycled restaurant oils and greases. It is biodegradable and less polluting than petroleum diesel. Common biodiesel feedstocks include virgin oils, used cooking oil, yellow grease, and brown grease. Biodiesel can be used in pure form or blended with petroleum diesel in vehicles and equipment. Common blends are B2, B5, and B20. Since used cooking oil is cheaper than virgin oils, it is a more economic feedstock choice for biodiesel producers. The estimated US demand for diesel fuel exceeds domestic vegetable and animal oil supply. Several companies in the Dallas-Fort Worth area produce
EFFECT OF INJECTION PRESSURE ON THE PERFORMANCE OF CI ENGINE FUELED WITH WCO
A comprehensive combustion analysis has been conducted to evaluate the performance of a commercial DI engine, water cooled two cylinders, in-line, naturally aspirated, RD270 Ruggerini diesel engine using waste vegetable cooking oil as an alternative fuel. In order to compare the brake power and the torques values of the engine, it has been tested under same operating conditions with diesel fuel and waste cooking biodiesel fuel blends. The results were found to be very comparable. The properties of biodiesel produced from waste vegetable oil was measured based on ASTM standards. The total sulfur content of the produced biodiesel fuel was 18 ppm which is 28 times lesser than the existing diesel fuel sulfur content used in the diesel vehicles operating in Tehran city (500 ppm).
The maximum power and torque produced using diesel fuel was 18.2 kW and 64.2 Nm at 3200 and 2400 rpm respectively. By adding 20% of waste vegetable oil methyl ester, it was noticed that the maximum power and torque increased by 2.7 and 2.9% respectively. The growing concern about energy resources and the environment has increased interest in the study of alternative energy sources. To meet the requirements of energy expenditure there has been a growing curiosity in alternative fuels such as biodiesel to provide a room for diesel oil appropriate for internal combustion engines. The need for fossil fuels and the emissions generated by these fuels increase daily.
Researchers are on the verge of global warming and climate change, and energy sustainability and the use of materials are important issues today. Biodiesel is another fuel to be put in place of diesel fuel by processing used cooking oil. However, the products formed during the frying process have influenced the transesterification reaction and the biodiesel properties. These experiments on the analysis of C.I. engine that uses diesel and residual cooking oil mixture. They can be recycled and used multiple times, thus offering a cheaper way to produce biodiesel. The advantages and disadvantages of these heterogeneous catalysts are presented. Future work focuses on the application of economically and environmentally sounds solid catalysts in biodiesel production using WCO as raw material.

review on diesel engine applications of biodiesels from non edible resources...
Over the number of years, biodiesel is being produced from various feed stocks that are from vegetable oils or animal fats and it is well established that biodiesel up to 20% blending in fossil diesel does not require any engine modification for use. Due to high cost involvement and food security in current situation for using edible resources to produce biodiesel, researchers in India are shifting attention towards non edible resources such as Karanja seed oil, Mahua oil, Jatropha seed oil, Cotton seed oil, Mesua ferrea seed oil, Yellow oleander seed oil etc which are available in ample amount throughout the subcontinent. Extensive research has been performed on the application of biodiesel produced from these non edible resources as a fuel in diesel engines in place of petroleum diesel. This review paper discusses application of biodiesel produced from different non edible feed stocks for their application in engines as an alternative to fossil diesel in terms of engine and emission performance.

D:\Semester\5th Sem\Ppt\Alternative Fuels
Alternative fuels are needed to meet rising energy demands while reducing greenhouse gas emissions. India relies on imports for 3/4 of its oil needs. Biofuels like biodiesel from palm and jatropha oil and bioethanol from sugarcane offer alternatives. Algal fuels from algae lipids offer high yields without using farmland. Natural gas and biogas can fuel vehicles when compressed as CNG or liquefied, and have lower emissions than gasoline. Electric vehicles powered by batteries or hydrogen fuel cells produce no emissions but have limited range, though fuel cell vehicles could go further. Plastic and emulsified diesel also show potential as alternative transport fuels.

Reduction of CO2 And Production of Biodiesel From Algae
The use of energy sources has reached at the level that whole world is relying on it. Being the major
source of energy, fuels are considered the most important. The fear of diminishing the available sources
thirst towards biofuel production has increased during last decades. Considering the food problems,
algae gain the most attention to be used as biofuel producers. The use of crop and food-producing plants
will never be a best fit into the priorities for biofuel production as they will disturb the food needs.
Different types of algae having the different production abilities. Normally algae have 20% to 80% oil
contents that could be converted into different types of fuels such as kerosene oil and biodiesel. The
diesel production from algae is economical and easy. Gene technology can be used to enhance the
production of oil and biodiesel contents and stability of algae. By increasing the genetic expressions, we
can find the ways to achieve the required biofuel amounts easily and continuously to overcome the fuels
deficiency. The present review article focusses on the role of algae as a possible substitute for fossil fuel as
an ideal biofuel reactant.

Continuous rise in the conventional fuel prices and shortage of its supply have increased the interest in the field of the alternative sources for petroleum fuels. Biodiesel is one such alternative source which provides advantage of pollution control. In the present work, experimentation is carried out to study the performance, emission and combustion characteristics of Rice-Bran biodiesel and diesel. In this experiment a multi cylinder, four stroke, naturally aspired, direct injection, water cooled, eddy current dynamometer, TATA Indica V2 diesel engine is used at variable speed condition. Crude oil is converted into biodiesel and characterization has been done. The experiment is conducted at variable speed condition. The engine performance parameters studied were brake power, brake specific fuel consumption, brake thermal efficiency. The emission characteristics studied are CO, CO2, UBHC, mean gas temperature, exhaust gas temperature and smoke opacity. The combustion characteristics studied are cylinder pressure, mass fraction burned, net heat release rate, cumulative heat release rate and rate of pressure rise. These results are compared to those of pure diesel. These results are again compared to the corresponding results of the diesel. From the graph it has been observed that, there is a reduction in performance, combustion characteristics and emission characteristics compared to the diesel. This is mainly due to lower calorific value, higher viscosity, lower mean gas temperature and delayed combustion process. The present experimental results show that Rice-Bran biodiesel can be used as an alternative fuel in diesel engine.

A Review on Biodiesel Production
Millions of people in India have been lifted out of poverty as a result of economic growth, and society has modernised. economic aspiration has not been accomplished without expense. Energy security has been impacted by Indias increased reliance on energy imports. Air quality is impacted by pollution from industry, transportation, and conventional cook stoves, which is also raising greenhouse gas emissions and accelerating climate change. India began producing biofuels about a decade ago in order to lessen its reliance on imported oil and so enhance energy security, and it is currently one of the leading producers of Jatropha oil. In 2001, the government launched a 5 ethanol blending E5 pilot programme, and in 2003, it established the National Mission on Biodiesel, with the goal of reaching 20 biodiesel blends by 2011 2012. Government of India, 2002, 2003 . Indias biofuel initiatives, like those of many other countries throughout the world, have suffered difficulties, owing mostly to supply constraints and global worries about food security. In 2009, Indias National Regulatory on Biofuels set a non mandatory aim of a 20 mix for both biodiesel and ethanol by 2017, as well as a broad plan for the biofuels programme and policy measures to support it. The purpose of the article is to examine how biofuels may be used in India to offset the countrys reliance on fossil fuels and cut greenhouse gas emissions. It will be discussed how biofuels have been used recently and historically in relation to recent changes in government policy. A whole lifecycle evaluation will be utilised to analyse sample materials crops, wastes, and residues that can be used for biofuels. Case studies showcasing biofuel utilizations failures and achievements will be provided as examples of the difficulties and possibilities for use of biofuels in India, as well as recommendations for their potential future use.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
