Exergetic cost analysis and sustainability assessment of an Internal Combustion Engine

This study deals with exergy cost analysis and sustainability assessment of a diesel engine, which runs with diesel no. 2 and two different biodiesel fuels at 1400 1/min test speed. Maximum total cost per exergy flow input rate and total exergy cost are found to be 12.5549 $/kW•year and 1728.312 $/year for one of the biodiesel fuels, respectively, while minimum values of these costs are ...

Sustainable biofuels technically near take-off

Boeing says it has proven the ‘technical viability’ of biofuels for use in commercial aircraft. Now the company wants to ‘accelerate’ the process of making biofuels available on a commercial scale. After four test flights by four major airlines – carrying engines of the four major manufacturers – the facts are clear to Bill Glover, Boeing’s commercial planes’ managing director of environmental ...

Assessment of fuel efficiency of neem biodiesel (Azadirachta indica) in a single cylinder diesel engine

Increase of petroleum diesel usage and its environmental pollution necessitate the study of alternate fuel production. Vegetable oils are the viable alternate form of non–polluted, renewable fuel to diesel engines. In this work, the non–edible oil, neem (Azadirachta indica) was used to produce biodiesel by a two step transesterification process. The fuel properties of the biodiesel thus produced ...

Parametric study of biodiesel quality and yield using a bench-top processor

Biodiesel is a renewable liquid fuel alternative to petrodiesel. It is produced by the transesterification of vegetable oil and alcohol in the presence of a catalyst. A 1.5 L bench-top biodiesel processor was constructed to study the effect of feedstock and operating conditions on the conversion and the biodiesel quality. Biodiesel was produced from several oil feedstocks using methanol and ...

Value stream mapping based on energy and cost system for biodiesel production

Organisations have to give more attention to customer demands for survival and also for increasing their market shares. But customers' demands are not stable. The main problem of all organisations is how to cut costs during production process. The solution to this problem is built up with lean–based production systems. Value stream mapping identifies those areas where unwanted productivity is ...

Development and measured performance of a batch reactor for biodiesel production from fresh and waste vegetable oils

The development and measured performance of a batch reactor for biodiesel production from fresh and waste vegetable oils as feedstock is presented. A biodiesel batch reactor was fabricated using locally sourced materials. Three different transesterification reactions were performed on the feedstocks using the fabricated reactor. The reaction temperature and time were varied for the fresh and ...

Energy and exergy analyses of a CI engine fuelled with palm biodiesel based on experimental data

Only energy analysis is not enough to define the best efficiencies of any system, so exergy analysis uses to understand and improve the actual efficiencies of the whole system. Energy analysis identified the energy losses but could neither identify the irreversible losses nor their location. These are, however, could be clearly explained with the application of exergy analysis. In this study both ...

The isoengine: realisation of a high-efficiency power cycle based on isothermal compression

A novel high-efficiency internal combustion engine for power generation and direct-drive applications is being developed. Distillate-fuelled power plants in units of 7 MW electrical output are predicted to reach a net electrical efficiency of 60%. An efficiency of 58% is targeted for the gas-fired version. This compares with a net electrical efficiency of about 45% for advanced reciprocating ...

The performance and emission characteristics of a diesel engine using preheated Kusum oil and Kusum diesel blend

Rapidly depleting conventional petroleum resources have prompted research for alternative fuels. Among various possible options for internal combustion engines, fuels derived from triglycerides (vegetable oils/animal fats) are a promising substitute for diesel fuel. Vegetable oils pose some detrimental characteristics like high viscosity and low volatility compared to diesel fuel. In the present ...

Investigation on combustion characteristics of crude rice bran oil methyl ester blend as a heavy duty automotive engine fuel

In the present work, an attempt was made to test the suitability of crude rice bran oil methyl ester (CRBME) blend as a heavy duty automotive engine fuel. A four stroke, six cylinder direct injection 117.6 kW turbo-charged compression ignition (CI) engine was used for the work. The operation of the engine with CRBME blend showed that the peak pressure increased with lower maximum rate of pressure ...

Performance and emission characteristics of a DI compression ignition engine operated on PODL biofuel

This paper presents the results of investigations carried out both numerically with the CFD code CONVERGE and experimentally on a single-cylinder, four stroke, direct-injection, CI engine. The tests are performed with neat diesel, neat palm oil (PO) and different blends of PO and the D-limonen solvent (PODL), like 10%, 15% and 20% by mass of D-limonen in PO (PODL10, PODL15 and PODL20). Engine ...

Meeting the challenges of biodiesel blend measurements

In a published paper on biodiesel blend quality submitted by the National Renewable Energy Laboratory1, the chief problem found with biodiesel blends was inaccurate blend ratios. Retail customers and fleet managers do not typically worry about whether the blend ratio is correct until a problem occurs. For fleet managers, an incorrect blend can mean a total shutdown of operations. On the ...

A hybrid multi–criteria decision support system for selection of optimum fuel blend

The increasing diesel consumption, depletion of fossil fuels and environmental concerns have prompted usage of biodiesel. The selection of appropriate source and blending of biodiesel plays a role in alternate energy production. The aim of this study is to evaluate the optimum blend using Multi Criteria Decision Making (MCDM) technique. Five alternative fuel blends are prepared by varying the ...

Guide to Measuring Biofuel Blending

As the global commitment to renewable energy sources grows, the importance of using biodiesel as a blending component with diesel fuel has increased. Biodiesel consists of fatty acid methyl esters (FAME) which are produced by the transesterification of certain feedstock oils, such as soy, rapeseed, canola, and others. The ...

Performance and emission characteristics of CI engine, fuelled with diesel and oxygenated fuel blends

Vegetable oils are a potential alternative towards partial or total substitution of diesel fuels. In this study, we used ethanol as the solvent, and a bio fuel enhancer as additive to explore the possible use of higher percentages of biodiesel in an unmodified diesel engine. Biodiesel was produced from cashew nut shell liquid (CNSL) by pyrolysis process. A mixture containing 80% (by volume) of ...

Effect of fuel additives on performance and exhaust emissions of direct injection diesel engine operating on B20 waste fish oil

The ever increasing diesel consumption, rapid depletion of fossil fuels and environmental concern has prompted an intensive use of biodiesel produced from various sources. In this study, biodiesel (ethyl ester of fish oil) was prepared from fish oil and different blends of biodiesel–diesel (B20, B40, B60, B80 and B100) were examined in a single cylinder, constant speed, and direct injection ...
