[ 1 ] - An Investigation of Energy Use Efficiency and CO2 Emissions for Grape Production in Zanjan Province of Iran

Objective: The aims of this study were to determine energy efficiency and CO2 use pattern of grape production in Zanjan province, Iran by a non-parametric method of data envelopment analysis (DEA). Methods: Initial data were collected using a face to face questionnaire from 42 orchards in Abhar city of Zanjan province which is one of the most important centers of grape production in ...

[ 2 ] - Performance and Emissions of a Tractor engine operating on biodiesel-diesel blends with EGR

The influences of different diesel/biodiesel blends and EGR rate on brake specific fuel consumption (BSFC), exhaust gas temperature, NO, HC, CO emissions, are studied and demonstrated. In this paper a four stroke direct injection, water cooled, diesel engine was used. Biodiesel either in neat form or as a blend with diesel fuel is extensively investigated to solve the twin problem of reduction ...

[ 3 ] - Evaluate the effect of biodiesel and EGR system on diesel engine emissions

Vehicle Emission is one of the main causes of environmental damage. Vehicle engines produce carbon dioxide (CO2), hydrocarbon (HC), Nitrogen oxides (NOx) and many other harmful substances. An investigation was conducted using a compression-ignition engine fuelled with different ratios of blends of diesel and biodiesel at different EGR rates. The effects of different ratios of fuel blends and EG...

[ 4 ] - بررسی تولید متان از پسماند مواد غذایی با استفاده از تابش مایکروویو : تاثیر توان و زمان تابش و ارائه سینیتک فرآیند

Background and purpose: Energy recovery from waste is an appropriate method for waste management and energy production from food waste. Energy production through waste incineration produces significant emission which is a critical threat for environment. Anaerobic digestion of the waste is a suitable way to produce clean energy. This study aimed to investigate the anaerobic digestion from food ...

[ 5 ] - امکان سنجی استفاده از سوخت گیاهی بیودیزل و نانواکسیدهای سریم و مولیبدن به عنوان افزودنی به سوخت دیزل در ارزیابی تراز انرژی موتور دیزل

در سالهای اخیر استفاده از روغنها و فرآورده های گیاهی به عنوان جایگزین سوخت دیزل مورد توجه قرار گرفته است. استفاده از روغن‌های گیاهی علاوه بر کاهش قیمت بیودیزل تولید شده، کمکی در جهت حفظ محیط زیست می‌باشد. تا کنون مناسب بودن روغن کلزا، سویا و روغن نخل در موتور دیزل پاشش مستقیم مورد ارزیابی قرار گرفته است. در موتورهای احتراق داخلی حدود یک سوم کل انرژی سوخت ورودی به کار مفید تبدیل می‌گردد.کاهش تل...

[ 7 ] - Investigation of performance and exhaust emission of diesel engine in different ratios of lambda coefficient using diesel-ethanol fuel blends

In recent decades, rising greenhouse gas emissions have become a major challenge and concern. Environmental pollution is one of the greatest human challenges of the 21st century. Improving the performance of internal combustion engines and reducing the amount of pollutant emissions has always been a concern for researchers. The use of alternative fuels and the control and adjustment of the lamb...
