چکیده
ذخایر سوخت فسیلی رو به اتمام است و استفاده از آن برای تولید انرژی بر محیط زیست نیز تأثیر می­گذارد. بنابراین، منابع انرژی پایدار و پاک باید تولید شوند تا نیازها را برآورده کنند. در این تحقیق، سوخت­های ترکیبی از متیل استرهای روغن کلزا، روغن سویا و پالم با سوخت دیزل تولید شد. برای دستیابی به مزایای بیودیزل روغن پالم (ارزش حرارتی بالا) و بیودیزل روغن سویا و کلزا (ویسکوزیته سینماتیکی کم)، مخلوط بیودیزل­های مختلف (BS10، BS20، BR10، BR20، BP10، BP20، BRSP10 و BRSP20) برای ارزیابی تأثیر آنها بر عملکرد موتور و انتشار گازهای گلخانه­ای در سرعت­های 1800 تا 2700 دور بر دقیقه با گام 300 دور بر دقیقه تحت شرایط بار کامل آزمایش شده است. خواص فیزیکی و شیمیایی همه مخلوط سوخت­ها با رعایت استاندارد ASTM D6751 اندازه گیری شد. برای تست موتور از موتور دیزل تک سیلندر هوا خنک، 4 زمانه و تنفس طبیعی استفاده شد. نتایج تجربی نشان داد که در همه سوخت‌های ترکیبی مقادیر توان و مصرف سوخت ویژه با افزایش سرعت موتور افزایش در حالیکه گشتاور کاهش می­یابد. همچنین مقادیر آلاینده نیز با افزایش سرعت موتور افزایش می­یابد. بر اساس نتایج، سوخت ترکیبی BP20 می تواند به عنوان سوخت جایگزین در موتورهای دیزلی بدون هیچ گونه تغییر موتور استفاده شود.

چکیده English

Fossil fuel reserves are running out and its use for energy production also affects the environment. Therefore, sustainable and clean energy sources must be produced to meet the needs. In this research, mixed fuels of methyl esters of rapeseed oil, soybean oil and palm oil were produced with diesel fuel. To achieve the advantages of palm oil biodiesel (high calorific value) and soybean and rapeseed oil biodiesel (low kinematic viscosity), different biodiesel mixtures (BS10, BS20, BR10, BR20, BP10, BP20, BRSP10 and BRSP20) were used to evaluate their effect on engine performance and greenhouse gas emissions at speeds of 1800 to 2700 rpm with a step of 300 rpm under full load conditions. The physical and chemical properties of all fuel mixtures were measured according to the ASTM D6751 standard. An air-cooled, 4-stroke, naturally aspirated single-cylinder diesel engine was used for different mixture testing. The experimental results showed that in all the combined fuels, the values of power and specific fuel consumption increase with increasing engine speed, while the torque decreases. Also, the number of pollutants increases with the increment of engine speed. Based on the results, BP20 mixture fuel can be used as an alternative in diesel engines without any engine modification.
