Abstract :
In this study, waste cooking oil methyl ester (WCOME) and diesel were blended in 20, 40, 60 and 80%
percentage volume basis. Biodiesel and the blends were tested in 4-cylinders, 4-strokes and direct injection
diesel engine to investigate the emissions and performance at engine speeds of 600-3000 rpm under idle and
full load. The result was compared to the data of petroleum diesel. The experimental data showed that the
emissions of biodiesel and blends were much lower than B100. In comparison, the emission of biodiesel was
more than 50% lower than B100. The average reductions were 76.19% for smoke opacity; and 97.62, 90.36 and
98.69% for brake specific emission factors of BS-HC, BS- CO and BS-SO , respectively. The engine 2
performances were also observed. Results showed that when WCOME were used both BHP and BMEP showed
slight reductions about 8.63% compared to diesel. However, higher fuel consumption, had been indicated by
the BSFC. The BSFCs of B100 were recorded to be 9.45% higher than biodiesel. The Highest BTEs were also
recorded at a maximum average percentage of 19.93%.

در اين مطالعه، از تركيب متيل استر موجود در پسماند روغن خوراكي ( WCOME ) و ديزل بر اساس درصد حجمي 20 ،40 ،60 و 80 ٪مخلوط شد . از بيوديزل و سوخت تركيبي در يك موتور ديزل با 4 سيلندر، 4 ، ضربه اي، و تزريق مستقيم استفاده گرديد و ميزان توليد گازهاي گلخانه اي و همچنين عملكرد سرعت موتور در 600 -3000 دور در دقيقه تحت بار غير كامل و كامل مورد آزمايش قرار گرفتند. نتايج به دست امده با داده هاي ديزل مشتق شده از نفت مقايسه شد . داده هاي تجربي نشان داد كه توليد گازهاي گلخانه اي از بيوديزل و سوخت تركيبي بسيار كمتر از B100 بودند . در مقايسه، انتشار بيوديزل بيش از 50 درصد كمتر از B100 بود . متوسط كاهش 76.19 ٪براي كدورت دود بودند و 62.97 ،36.90 ،و 98.69 ٪براي قطع عوامل انتشار خاص از -BS HC ،CO-BS ،و SO2-BS بود. عملكرد موتور نيز مورد بررسي قرار گرفت. . نتايج نشان داد كه زماني كه WCOME مورد استفاده قرار گرفت كاهش كمي در مورد BHP و BMEP حدود 63.8 ٪ در مقايسه با ديزل نشان . دادند با اين حال، مصرف سوخت بالاتر، توسط BSFC نشان داد شده است . BSFCs از B100 به 9.45 درصد بالاتر از بيوديزل ثبت شده است. بالاترين BTEs نيز در حداكثر 19.93 ٪گزارش شده است
