Dr.Hassan Elobied Hassan ,Prof. Sabir Mohamed Salih ,2009, PERFORMANCE OF A DIESEL ENGINE USING SUDANESE PEANUT OIL AS A FUEL.,Journal of Science and Technology,10 (2) ,pp:17-45

By Dr.Hassan Elobied Hassan ,Prof. Sabir Mohamed Salih ,
The world has recently faced fossil fuel depletion and environmental degradation that triggers the research for using alternative modes. Bio-fuels appear to be one of the most reliable and recommended ones. Sudan potentiality of producing bio- fuels is highly promising and can be quite feasible since enough fertile land, water and suitable climate are available. In this paper production of sudanese peanut oil methanol ester was attempted and tested in a 4-stroke diesel engine for performance evaluation and compared with fossil fuel. Using transesterification process at volumetric ratio of 40oil: 12methanol: 1 NaOH, a temperature of 60 0c and stirring for one hour time, produced a bio-diesel of better properties as an acceptable substitute for conventional diesel fuel. Without any need for engine systems modifications, engine performance was improved and exhaust emissions were highly reduced.
يواجه العالم اليوم مشكلتي تناقص مخزون الوقود الحفري واتساع استخدامه والتدهور البيئي من انبعاث غازات احتراقه التي تساهم في تهديد كوكبنا بالاحتباس الحراري، مما ادى الى توجيه البحوث عالميا نحو الوقود الحيوي كافضل بديل لحل هذه المشكلة مستقبلا. في هذا البحث استخدم زيت الفول السوداني لانتاج الوقود الحيوي الميثانولي بمساعدة هيدروكسيد الصوديوم، وباستخدام نسبة حجمية 40 زيت : 12 ميثانول : 1 هيدروكسيد صوديوم واجراء خلط مستمر لمدة ساعة في درجة حرارة 60 درجة مئوية، تحقق مستوى افضل لخواص وقود الديزل الحيوي مقارنة بخواص وقود الديزل التقليدي. وباختبار هذا الوقود في محركات ديزل بدون اي تعديل كان مستوى الاداء مشابها لأداء الوقود التقليدي وانبعاث غازات العادم منخفضا مما يؤكد تقليل تلوث البيئة. للسودان امكانية كبيرة من اراضي زراعية، ومياه، وطاقات طبيعية وبشرية مما يمكنه من انتاج هذا الوقود والتنافس به في السوق العالمي محققا استراتيجية اقتصادية واجتماعية مقدرة.
