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 ...

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 ...

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 ...

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 ...

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 ...

Combustion, performance and emission characteristics of a DI CI engine using biodiesel with varied fatty acid composition
Five Biodiesel produced from different vegetable oils were tested on a diesel engine to study the effect of biodiesel fatty acid composition specifically unsaturated composition on the engine combustion. The results from fuel analysis show that biodiesel (93% unsaturated fatty acid ester composition) with 55% linolenic ester has a higher density of 0.89 kg/m³, lower viscosity of 3.8 cSt, heating ...

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 ...

On-Vehicle Exhaust Gas Cooling in a Diesel
ABSTRACT A diesel emissions control system built and tested on an industrial forklift truck is described. The system utilizes a pleated media type diesel soot filter. The temperature limit of the filter material is well below the temperature of the exhaust gas. Therefore, cooling of the exhaust gas is necessary. A finned-tube heat exchanger is included in the system to cool the exhaust gas to ...

Soot level – a diesel engine lube oil condemning limit
While there is widespread disagreement on used-diesel oil condemning limits, it is well known that excessive soot in the lube oil causes abnormal valve and injection-train wear. It can also increase exhaust emissions and clog filters. Typically, the suggested limit for soot is in the neighborhood of 3% but can go much higher. With the new ASTM Method D7686, truck, bus, ship, locomotive, and ...

Taking matters into hand - Case Study
Biofuels must be up to scratch as contaminated or improperly blended fuel can damage a company’s bottom line. To ensure product quality several options exist including laboratory analysis, field test kits and portable lab instruments. Laboratory testing would be the ideal solution if everyone had the budget and the time to wait for the results. But in a market where time is money, quick ...
