  • 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 ...

  • Biofuels effluent, does it exceed regulatory limits?

    The US Environmental Protection Agency (EPA), as well as other regulatory agencies around the world, have established limitation guidelines for discharges of “oily wastes” from facilities utilizing any type of oil and grease in their manufacturing process. However, recently several biodiesel plants in the US have been fined for illegally discharging vegetable-based oil and grease and polluting ...

  • 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 ...

  • 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 ...

  • Simulating switchgrass growth and development under potential and water-limiting conditions

    Anticipating a demand for switchgrass (Panicum virgatum L.) as a source for biofuel production, a crop simulation model of this crop can be a component of a biofuel decision support system. The objective of this effort was to develop and test a model for switchgrass, based on robust empirical relationships between plant behavior and the environment. The model simulates date of annual growth ...

  • A review on exergetic analysis and assessment of various types of engines

    This study presents a review on energy and exergy analysis of Otto and Diesel engines. Calculation methods of the analysis are discussed in detail. Previous studies, from 1963 to 2008, are chronologically listed and studied. The test engines had different cylinder numbers, speeds and rated powers. Engine specifications and test bench schematics are given in tables and figures. The best exergetic ...

  • EC Commissioned Study Finds Increased ILUC As A Result Of EU 2020 Goals

    On March 11, 2016, a consortium made up of Ecofys, the International Institute for Applied Systems Analysis (IIASA), and E4tech announced that the final report on the Land Use Change (LUC) study is now available online. The study was commissioned and funded by the European Commission (EC) and was focused on using the GLOBIOM model to determine ILUC associated with the ten percent renewable energy ...

  • 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 ...

  • 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 ...

  • Maintaining biodiesel quality standards

    A problem that is sometimes encountered with biodiesel blends is inaccurate blend ratios. This article describes a quick analytical method to assess blend ratios and ensure fuel performance. According to a study1 done by the National Renewable Energy Laboratory, the chief problem found with biodiesel blends was inaccurate blend ratios. Retail customers and fleet managers do not typically worry ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
