Dual Bio-Fuel As An Alternate Fuel For CI Engines With Enhanced Physical And Chemical Properties

reasons the alternative energy resources are becoming more attractive as they are renewable, sustainable and produce less or no emissions as compared to conventional fuel. Biodiesel is easily renewable, eco-friendly, non-toxic, and has wide availability compared to conventional used diesel fuel[1], [2]. It is an alternate fuel derived from the vegetable oil which could be first or second generation or animal fats[3], [4]. Biodiesel is produced through different methods like Blending, Emulsification, Pyrolysis and Trans-esterification[5]. The common approach to produced biodiesel is through a simple process called transesterification, as it is the easiest way to produce biodiesel. Lots of work have been done on Jatropha, Palm and other oils which are mostly based on one oil biodiesel, i.e. just blending single biodiesel into diesel. Fewer work has been reported by combining two separate biodiesel blends with mineral diesel [6]. Hass et al.[7] have reported that using a blend of soybean soap stick biodiesel with mineral diesel in 20:80 ratio by volume could reduce CO, HC, and PM emissions by 2.40%, 27.70%, and 19.70 % respectively when comparing to standard diesel. Hifjur Rahman et al.[8] found a good fuel combustion emission and 21% fewer soot deposits by using B10 blends of Simarouba oils and Mahua oil in the ratio of 50:50 with mineral diesel oil.

Dual fuel combustion in a CI engine powered by blended diesel biodiesel fuel and simulated gasification gas

Biodiesel has similar physico-chemical features with that of fossil-based diesel fuel on the likes of lower calorific value, viscosity, density, pour pint and flash point. Such features help the fuel to draw more attention by researchers in the field [9]. Biodiesel is better than diesel with regard to the environmental friendliness and its sustainability are the most known advantages of biodiesel that it has as compared to gasoline and diesel [6]. Biodiesel is characterized by the presence of oxygen that it contains (10–11% by weight), it is free aromatic fuel with higher cetane number compared to fossil fuels. These biodiesel properties lead to lower exhaust emission when combusted in CI engines instead of diesel [10]. Little or no modification is needed for engine operation with biodiesel fuel [7].

BIODIESEL A RENEWABLE ALTERNATE CLEAN AND ENVIRONMENT FRIENDLY FUEL FOR PETRODIESEL ENGINES: A REVIEW

BIODIESEL A RENEWABLE ALTERNATE CLEAN AND ENVIRONMENT FRIENDLY FUEL FOR PETRODIESEL ENGINES: A REVIEW

The use of biodiesel in a conventional diesel engine results in substantial reduction of unburned hydrocarbons, carbon mono-oxide and particulate matter. Emissions of nitrogen dioxide are either slightly reduced or slightly increased depending upon the duty cycle or testing methods. Biodiesel decreases the solid carbon fraction of particulate matter (since the oxygen in the fuel enables more complete combustion to CO 2 )

Experimental Evaluation of Performance and Emissions of Dual Blended Bio Diesels with Diesel as an Alternative Fuel for Diesel Engines

Experimental Evaluation of Performance and Emissions of Dual Blended Bio Diesels with Diesel as an Alternative Fuel for Diesel Engines

Previous research works found out that high kinematic viscosity and density fuels with lower calorific value tend to increase the BSFC and lower the brake power as it results in poor atomization of fuel during spraying of fuels inside the combustion cylinder. The presence of high amount of oxygen molecules in biodiesel results in complete combustion of fuel. This condition leads to lower hydrocarbons and carbon monoxide emissions. The other uses of biodiesel include its use as heating fuel in boiler furnaces, as a fuel in electricity generators to produce electricity, as a lubrication additive, as a fuel in transport industry including marine industry etc. Also it promotes agriculture as it is produced from plants and animal fats.

To Study of Vegetable Oils and Their Effects on Diesel Engine Performance

To Study of Vegetable Oils and Their Effects on Diesel Engine Performance

Mariusz et al.[17]conducted experiments on sunflower oil and recommended incorporating dual fuel pre-heater for durability improvements of diesel engines. The durability of the engine increased through the prevention of engine operation at low load and low speed conditions, reduced exposure time of fuel injection sys- tem at very high temperature conditions during transition process from high to light loads and elimination of fuel injection of oil during shut down period.Samagaoperated a single cylinder water-cooled dual fuel engine using sunflower oil and groundnut oil. The performance characteristics obtained are comparable to that of diesel. He suggested some remedies to the practical problems encountered in the dual fuel operation of I.C. engines. Periodic cleaning of the nozzle tip is necessary to ensure adequate spray characteristics. Starting and stopping with diesel oil while running with vegetable oil eliminates filter clogging. Bio-diesel produced from vegetable oil is of higher unsaturated fatty acids and bio-diesel from animal fats is of higher content in saturated fatty acids. Kelvin et al.[18]attempted to identify the mechanism for bio-diesel emission reduction and engine performance by blending. He concluded that bio-diesel's particulate reducing effect could be attributed to its displacement

Air Pollution Reduction and Environment Protection Using Methane Fuel for Turbocharged CI Engines

In this study the effect of methane gaseous fuel on the performance and emissions of turbo- charged compression ignition engine was inves- tigated. The engine ran with various CH 4 /diesel ratios under full load. The results show that the brake power and thermal efficiency increased while the fuel consumption decreased for high CH 4 concentration in the mixture. Moreover, NO emission reduced by 35% compared to neat die- sel fuel when 50% of methane was added to the mixture. Conversely, the CO and HC concentra- tion increased when the methane ratio was less than 50% compared to neat diesel combustion. To conclude, the turbocharger and alternative fuel are promising green techniques to reduce the en- gine emissions and air pollution.

Biomass Briquette System: Pollution Free Thermal Energy Resources

Biomass Briquette System: Pollution Free Thermal Energy Resources

ABSTRACT: Biomass Briquette, a dense form of bio-fuel has gained a large popularity in poor developing countries as an alternate cooking fuel. Within a short period it has replaced traditional fuels for its availability and high acceptance in user level. In a country like India, where 67% people relay on traditional bio- fuel for energy, briquette has received an immense response. Although large volume of work has been done on developing its production process, little data is available on its physical and fuel properties and reasons behind its high acceptance. The paper consists summery of the findings gained from a research conducted on briquette in India, its physical and fuel properties and field survey on local acceptance. The idea is widely in innovation globally. One can browse “n” number of development that is being taking place regarding biomass briquettes. Our search for such development led us to conclusion that all the biomass around the world, surely there is a way of recycling, providing clean environment. Moreover, as we have seen very few have utilized bio waste, providing clean environment. We were encouraged to find the reason behind it. We decided to look into the possibilities of recycling through such wastage.

Investigation Of Bio-Fuel Production And Performance Characteristics Of Ci Engine

Investigation Of Bio-Fuel Production And Performance Characteristics Of Ci Engine

Under Indian condition only non-edible oil can be used as biodiesel which are produced inappreciable quantity and can be grown in large scale on non-cropped marginal lands and waste lands. Non-edible oils like jatropa, karanja and mahua contain 30% or more oil in their seed, fruit or nut .The uncertainty of petroleum-based fuel availability has created a need for alternative fuels [1]. Hence research on biodiesel as an alternative of diesel is in progress. Biodiesel is renewable fuel, it has simple technology of production, low handling hazards, emits low pollutants, and can be used in engine without substantial modifications [2]. The main source of biodiesel i.e. oil producing plant, can grow easily in wide range of geographic locations and flexible climatic conditions. Among the edible and non-edible vegetable oils, the non-edible oils such as jatropa, karanja, putranjivaetcare economical as biodiesel for its less consumption in domestic purposes. It is widely agreed that biodiesel decreases the emissions of carbon monoxide (CO), carbon dioxide (CO2) particulate matters and nitrogen dioxide (NO2). It is also said to be carbon neutral as it contributes no net carbon dioxide to the atmosphere [3]. Other countries have seriously considered the massive use of bio energy in the future. China [4], Germany [5],Austria [6] and Sweden [7] have set goals of utilizing 10–15% of their internal primary energy supply through bio-energy up to the year 2020, where Vietnam has set a target of using bio energy i.e. 37.8% of the total energy consumption [8]. Different researchers have tried to produce biodiesel from vegetable oils either by enzyme, acid or alkali .Many of them reported about 97.7% conversion to production transesterification reaction within 18 minutes by using 1% KOH catalyst at 65°C.They have studied the transesterification reaction of sunflower and soybean oil sat different temperature and different molar ratio. He got the conversion from 90 to 98%.Literature shows already that many researches are done on non-edible vegetable oils such as jatropa, mahua, karanja, neem, etc. and edible vegetable oils separately to study the performance and emission characteristics of these in diesel engine. Jatropa, karanja and putranjiva plants are abundantly available in tropical and subtropical regions such as India, Bangladesh. The seeds from these plants go waste annually which can be utilize for biodiesel production and hence may solve partly fuel crisis problem. The present conventional fuel crisis has inspired the authors to compare the performance and emission characteristics of Ricardo variable compression diesel engine using transesterified oils of karanja, or jatropa or putranjiva and select the best one for the use in diesel engine.

Impacts and Challenges of Biodiesel Use in Transport sector – An overview

Impacts and Challenges of Biodiesel Use in Transport sector – An overview

Exhaust gas recirculation can be used to give NOx reduction up to 15% effectively without much adverse effect on the performance, smoke and other emissions. Higher EGR of 20 and 25% resulted in inferior performance and heavy smoke Because of the increased inlet charge temperature due to HOT EGR and dynamic injection advance, 5 and 10% EGR levels are not sufficient to reduce NO emission at all loads for JBD. However, these EGR levels significantly reduced NO at peak loads. About 15% of EGR, on JBD is found to be effective in reducing NO emission to values lower than that of diesel, without EGR, at all loads. Full load NO emission from JBD with 15% EGR, is found to be lower than that of corresponding diesel NO emission. Inherent oxygen present in the bio-diesel structure is believed to have played a significant role in compensating for oxygen deficient operation under EGR. JBD is found to be environmental friendly as far as CO and HC are considered. Smoke emission from JBD is found to be lower than diesel at peak loads with and without EGR. Smoke emissions are found to be higher for JBD in the lower load region because of slightly higher viscosity, low volatility and probably due to the presence of water content. NO emission from JBD is found to be comparatively higher than the diesel fuel (V. Pradeep et al., 2007).
