SpectrOil — The Accurate and Dependable Choicefor In-Service Oil And Fuel Analysis
Introduction The basis of modern oil analysis programs is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants, and additives in oil samples. Whatever an oil lab may need to measure, multi-elemental analysis is the core of an in-service oil analysis program. This paper gives an overview of Rotating Disc Electrode Optical ...

InfraSpec VFA-IR Spectrometer for Biodiesel Blend Measurements
Synopsis: Simple, yet powerful, filter-based IR spectrometers are ideal for compliance to the new ASTM 7861 test method for accurately measuring biodiesel blend ratios. The Wilks InfraSpec analyzer was the instrument used to develop and validate this method and thus is the industry standard for field measurement of FAME (Fatty Acid Methyl Ester) blend percentages. Introduction: Biodiesel is a ...

Mission Goundi, Republic of Chad, Central Africa - Case Study
Installed for testing at the Polytechnic University of Catalonia in Barcelona, Spain, this PP20 is destined to be transported to the village of Goundi, Chad in Central Africa. The project is being done through the University, also known as Barcelona Tech, with support from Misión y Desarrollo para Goundi, a Chad based NGO. One of the reasons they chose to develop a biomass-based power ...

Integration of Fischer-Tropsch fuel production with a complex oil refinery
The oil refining industry is facing harder policies on renewable content in its products. One way to meet this is to produce diesel and gasoline from gasification of biomass via a Fischer-Tropsch (FT) synthesis. In this paper, heat integrating a biomass-to-FT syncrude process with a refinery is compared to a stand-alone biomass-to-FT syncrude process, in terms of the consequences for GHG ...

A study on the thermodynamic analysis of a cascaded latent heat storage system over the single storage tank system for diesel engine waste heat recovery
This article presents the comparison of performance of a cascaded Latent Heat Storage (LHS) system over the Single Storage Tank (SST) system for heat recovery from a diesel engine. The energy and exergy saved and efficiencies during the charging process are evaluated and reported using actual system data. The discharge process is analysed with a case study and it is concluded that it is possible ...

Comparative assessment of injection, combustion, performance and emission characteristics of a diesel engine for biodiesel–diesel blends
The effects of different percentage of biodiesel diesel blends on injection, combustion, performance and emission characteristics of a constant speed diesel engine are analysed. The dynamic injection timing advanced with all blends. The in–line pressure and in–cylinder injection duration increased for the biodiesel blends in order to maintain same power output. The premixed combustion and total ...

Performance and energy analyses of a diesel engine fuelled with Koroch seed oil methyl ester and its diesel fuel blends
Performance of a single cylinder four–stroke diesel engine is analysed in the light of first law of thermodynamics in this study considering 10% (B10) to 40% (B40) (by volume) blending of Koroch seed oil methyl ester (KSOME) with diesel as fuels. An energy balance study is carried out to quantify the various losses associated with diesel engine processes on the basis of experimental data. ...

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 ...

The comparative analysis of diesel engine combustion and emission parameters fuelled with palm oil methyl esters and its diesel blends
In this work, the combustion and emission characteristics of a direct injection compression ignition engine fuelled with diesel-Palm Oil Methyl Ester (POME) blends are investigated. This study shows that the ignition delay decreases with increase in the POME addition. The maximum rate of pressure rise and maximum rate of heat release decreases with increase in POME addition at all loads. As the ...

Meeting the Challenges of Biodiesel Blend Measurements with Portable Mid-Infrared Analyzers - Case study
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 ...

Study of the performance and emissions of a high-speed direct injection diesel engine operating on ethanoldiesel fuel blends
An experimental study is conducted to evaluate the effects of using various blends of ethanol with normal diesel fuel, in blend ratios of 5/95, 10/90 and 15/85, on the performance and exhaust emissions of a high-speed, direct injection (DI), Ricardo/Cussons 'Hydra' diesel engine. The tests are conducted using each of the above fuel blends or neat diesel fuel. Volumetric fuel consumption, exhaust ...

Exergy analysis of a steam power plant: a case study in Iran
In the last decades, exergy analysis, based on the second law of thermodynamics was a method that substituted the energy analysis in studying thermodynamic systems. In this paper, the cycle of a power plant and its details, with two kinds of fuels, natural gas and diesel, have been analysed at its maximum load and the two factors, losses and exergy efficiency, which are the basic factors used to ...

Putting the brakes on biodiesel
Come December 31st, the Texas Commission on Environmental Quality (TCEQ) is set to effectively ban biodiesel in the state’s largest markets. The problem, they say, lies with the fuel’s nitrogen oxide (NOx) emissions and their contribution to the formation of ground-level ozone in Texas’ eastern counties. According to the TCEQ, biodiesel does not meet the stricter NOx standards recently imposed ...

Exergy analysis of a diesel engine cycle and its performance improvement
This paper aims to evaluate available energy losses, i.e. exergy losses caused by irreversible processes in the theoretical cycle of two-stroke and four-stroke diesel engines. All exergy losses in these cycles have been divided into three categories: exergy loss in the heat receiving process which is inevitable in thermal power systems; exergy loss in the scavenging process peculiar to the ...
