waterwashing or biodiesel purification is one of the steps in biodiesel fuel processing. waterwashing of the fuel is an indispensable processing stage, due to the presence of impurities in the fuel. in this research work, some of the effective parameters in biodiesel waterwashing and the optimum conditions which lead to economy in time and cost of waterwashing were investigated. the effective p...
بررسی ارزش غذایی تاغ و عمل آوری آن با سود و آهک در مراحل مختلف رشدبا استفاده از روش کیسه های نایلونی
abstract this study is carried out to determine the chemical composition in the three vegetative stages of the haloxylon sp., degradation parameters, with adding naoh and ca(oh2 ). for this purpose, in may and october and january 2010 enough some haloxylon sp. of the ammary area was prepared. crude protein and ash percentage are decrease, neutral detergent fiber percentage with pragress stage ...
مطالعات و بررسی های انجام گرفته نشان می دهد ترکیبات بودار موجود در fuel oil عمدتا ترکیبات سولفوردار سخت مثل تیوفن، دی متیل بنزوتیوفن و ... بوده و روشهای بوزدایی همچون استخراج با حلالهای اسیدی و بازی ، رقیق کاری با گازولین ، ماسکینگ با بوتیل استات نتایج چندان مطلوبی در بوزدایی از آن نشان نمی دهند.همچنین روش جذب سطحی برای بوزدایی fuel oil تنها با استفاده از جاذب هایی همچون بنتونیت و توفیت...
Fuel cell is one of the best alternatives of fossil energy. However, there are still two barriers: the durability and reliability, which block the wide application of fuel cells. To overcome these barriers, fault diagnosis is an efficient solution. This paper proposes a method for detection of common faults occurring in membrane electrode assemblies (MEA) of fuel cells using image processing to...
nowadays, utilization of blended fuel in internal combustion engine is one of main topics in vehicle industries. the synergy effect will be highlighted when the potential of each fuel is employed and the engine performance will improve consequently. in this research, the laminar flame speed of methane (main component of reference fuel for natural gas) and isooctane (main component of reference...
Experiments are performed to investigate the effects of fuel spray on in-cylinder mixture preparation and its impingement on cylinder walls and piston top inside a direct-injection spark-ignition engine with optical access to the cylinder. Novel image processing algorithms are developed to analyze the fuel impingement quantitatively on in-cylinder surfaces. The technique is useful to optimize t...
In view of the stringent CO intolerance of the state-of-the-art proton exchange membrane (PEM) fuel cells, it is desirable to explore CO-free fuel processing alternatives. In recent years, step-wise reforming of hydrocarbons has been proposed for production of CO-free hydrogen for fuel cell applications. The decomposition of hydrocarbons (first step of the step-wise reforming process) has been ...
We present an industrial case study in automotive control of significant complexity: the new common rail fuel injection system for Diesel engines, currently under production by Magneti Marelli Powertrain. In this system, a flow–rate valve, introduced before the High Pressure (HP) pump, regulates the fuel flow that supplies the common rail according to the engine operating point. The standard ap...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
