This work is based on the performance of biodiesel blends with diesel in providing for a suitable alternative fuel. There are various methods in which the biodiesel blends are made. Every approach uses the preparation of biofuel initially from a parent oil blend. Here cottonseed oil is taken to make biodiesel. For the conversion ionic liquids have been used as catalysts. The process of transesterification has shorter reaction times with ionic liquid usage. Then subsequently test is made on a diesel engine particularly suited for alternative fuels to find out the biodiesel performance. All the tests to find the suitability of the transesterified biofuel for use in a diesel engine have been done and results presented. The performance graphs show B30 to be the optimum based biofuel blend for which maximum efficiency has been found.

The decline in fuel oil production has led to the development of alternative fuels that are renewable and more environmentally friendly. An alternative fuel that can be developed is biodiesel. In this study aims to develop alternative biodiesel fuels as a substitute for fossil oil fuels that are feasible applied to diesel engines. This study conducted a diesel engine performance test using mixed fuel from pertadex and biodiesel Aleurites Moluccana with a variation of biodiesel mixture B10, B20, and B30. From the test results using a mixture of biodiesel, the ef ective power and torque produced by the engine decreases compared to using pure pertadex. Among the three variations of the biodiesel mixture, the best ef ective power produced by B10 fuel is 277 Watt and the best torque produced by B10 fuel is 1,238 Nm. Specific fuel consumption in all biodiesel blends is increased compared to pure pertadex. Among the three variations of the biodiesel mixture, the best specific fuel consumption produced by B30 fuel is 1197,67 g/kWh. The thermal ef iciency in all biodiesel blends is increased compared to pure pertadex in B20 and B30 blends. Among the three variations of the biodiesel mixture, the best thermal ef iciency produced by B20 fuel is 7,883 %. The opacity of the engine exhaust gas produced in all biodiesel mixes is getting better compared to using pure pertadex. The best opacity of the engine exhaust gas produced in the use of B30 fuel is 2,3% HSU. Keywords: Biodiesel, Aleurites Moluccana, Diesel Engine Performance, Opacity

 The rate of fossil fuel consumption is soaring with population growth but the fossil fuel reserves are finite in nature. It is only a matter of when they run out - not if. Every year, billions of tons of fossil fuel oil is consumed globally. So it is high time we contemplated over other alternative fuels. One such alternative is the use of Straight Vegetable Oil (SVO) or its blend in diesel engine if performance, emission and maintenance of an engine are comparable to diesel fuel. The main objective of this research was to evaluate the effectiveness of commercially available Soybean oil and diesel blends on the performance characteristics of Kirloskar single cylinder diesel engine. This study also sheds light on comparison and measurement of physical properties of diesel and test fuels i.e., the blends, and correlates them with the performance test result. It is concluded that the tested blends can be used safely and effectively in the diesel engine, at least in small blending ratios with normal Diesel fuel.

This paper presents the result of investigations carried out in studying the emission and performance of diesel engine using the castor biodiesel and its blend with diesel from 0% to 40% by volume. The acid-based catalyzed transesterification system was used to produce castor biodiesel and the highest yield of 82.5% was obtained under the optimized condition. The FTIR spectrum of castor biodiesel indicates the presence of C=O and C–O functional groups, which is due to the ester compound in biodiesel. The smoke emission test revealed that B40 (biodiesel blend with 40% biodiesel and 60% diesel) had the least black smoke compared to the conventional diesel. Diesel engine performance test indicated that the specific fuel consumption of biodiesel blend was increased sufficiently when the blending ratio was optimized. Thus, the reduction in exhaust emissions and reduction in brake-specific fuel consumption made the blends of caster seed oil (B20) a suitable alternative fuel for diesel and could help in controlling air pollution.

The research activities related to alternative fuels has gained prominence, due to exhaustion of the present fossile fuels and rise in pollution levels. Any substitute to diesel will help mankind for safeguarding the environment due to redced usage of conventional fuels, as diesel consumption is high in goods transshipment sector and cultivation fields.Suitable replacement for diesel are Vegetable oils, because their cetane value is nearer to pure diesel. The combustion related issues with vegetable oils, either edible or nonedible can be resolved to a major extent by esterifying them.For this study the biodiesel extracted from used cooking oil, was used as fuel, in a 3.68 kW, 1500 RPM stationary diesel engine at distinct injection timings.The injection timings were changed by keeping copper shims between body of fuel pump and frame of diesel engine. The value of optimum injection timing(where maximum efficiency is obtained) was observed to be 310 forbiodiesel and diesel fuels. The performance parameters, combustion characteristics and pollution levels were recorded, at recommended and optimum timings of injection of 270 and 310 before the top dead centre(bTDC).Studies were conducted with pure diesel and biodiesel, made using waste fried vegetable oil (WFVOBD). The biodiesel showed equivalent performance at both manufacturer recommended and experimentally obtained optimum injection timings, but marginally increased levels of NOx .

In the present scenario of increased industrialization and transportation in the world leads to increased consumption of fossil fuels which in turns leads to depletion of fossil fuels at a faster rate. Fossil fuels combustion is the dominant source for greenhouse gases and global warming. In view of energy crisis raised in 1970’s and environmental concern, many researches are directed towards search of alternative fuels which can replace consumption of fossil fuels as well as reduce pollution. In developing countries like India which is agriculture land the best alternative fuels are biodiesel and ethanol as they are produced from renewable feedstocks like sugarcane, corn etc. and they are also less hazardous to environment because of lower emission property. Ethanol blends results in significant reduction of emissions of hydrocarbon (HC), carbon monoxide (CO) and particulates matter but increase in nitrogen oxides (NOx). The main purpose of ethanol addition is to reduce the viscosity of biodiesel blends. This paper represents significance of Compression Ratio(CR) on performance, combustion and emission of single cylinder four stroke CI diesel engine by using various compression ratios such as 17.5:1, 18.5:1 and 19.5:1. Experimental research has been conducted with four types of ethanol blends, namely E10, E20, E30 and E40. Ethanol-biodiesel mixture mixed with 2% emulsifier 1% diethyl carbonate and 1% ethyl acetate to maintain similarity and to avoid phase separation. Ethanol subjected to high compression ratio has been used to increase brake thermal efficiency (BTE). The compression ratio has been increased to improve the combustion and performance of the diesel engine.

Oil based fuels worldwide have not just brought about the speedy consumption of available energy sources, yet have likewise caused extreme air pollution. The quests for a substitute fuel has prompted numerous findings because of which wide assortment of alternative fuels are available now. The current investigations have revealed the utilization of vegetable oils for engines as an option for diesel fuel. Since there is a restriction in using vegetable oils in diesel engines because of their high viscosity and low volatility. In the current work, mango seed oil is converted into respective methyl ester by transesterification process. Tests are conducted using different blends of methyl ester of mango seed oil with diesel in a diesel engine. The investigation consequences demonstrated that the MEMSO biodiesel has comparable qualities to that of diesel. The brake thermal efficiency and smoke are seen to be lower in case of MEMSO biodiesel blends than diesel. Then again, BSFC and NOx of MEMSO biodiesel blends are seen as higher than diesel. It is observed that the combustion characteristics of methyl ester of mango seed oil blends seem to be similar with that of the diesel. From this investigation, it is concluded that B25 as optimized blend and could be used as an alternative fuel in a diesel engine with no engine modifications

Recent increases in petroleum fuel costs, CAFE standards, and environmental concerns about CO2 emissions from petroleum based fuels have created an increased opportunity for diesel engines and renewable alternative fuels such as biodiesel. Additionally, the Environmental Protection Agencies Tier II heavy duty and light duty emissions regulations require significant reductions in NOx and diesel particulate matter emissions for diesel engines. As a result, the diesel engine and aftertreatment system is a highly calibrated system that is sensitive to changing fuel characteristics. This study focuses on the impact of soy methyl ester biodiesel blends on combustion performance, carbonaceous soot matter and NOX emissions. Tests were completed with an I4 1.9L, turbocharged, high speed, direct injection diesel engine using commercially available 15 ppm ultra low sulfur diesel, a soy methyl ester B20 (20% biodiesel and 80% ultra low sulfur diesel) biodiesel blend and a pure soy methyl ester biodiesel. Results show a reduction in NOx and carbonaceous soot matter emissions and an increase in brake specific fuel consumption with the use of biodiesel. Further, traditional methodology assumes that diesel fuels with a high cetane number have a reduced ignition delay. However, results from this study show the cetane number is not the only parameter effecting ignition delay.
