Abstract :
An experimental investigation was carried out to analyze the performance and emission characteristics of a diesel engine fuelled with biodiesel blends (10, 20 and 30%) obtained by mixing karanja and linseed oil and diesel. Brake thermal efficiencies of biodiesel blends were found to be comparable with diesel with a slight reduction. BSEC increased with the proportions of biodiesel in biodiesel blends. B30 was found to cause the lowest HC emissions and the lowest CO emissions and diesel was found to deliver the lowest NOx emissions among the fuels used at all loads. Considerable reduction up to 37.32 % was found in smoke opacity of biodiesel blends. The study revealed that 10% biodiesel blend can be effectively used in an unmodified diesel engine.

يك مطالعه تجربي براي تجزيه و تحليل عملكرد و ويژگي هاي نشر (گاز) موتور ديزل كه با بيوديزلي تركيبي (10، 20 و 30 درصد) كه با مخلوط كردن روغن karanja و روغن بذر كتان و ديزل به دست آمده بود، پر شده بود، انجام شد. بازده حرارتي ترمز بيوديزل با ديزل با كاهش كمي قابل مقايسه بود. BSEC با افزايش نسبت بيوديزل در سوخت مخلوط افزايش يافته است. B30 كمترين انتشار HC و CO را موجب شد و مشخص شد كه ديزل كمترين مقدار انتشار را در ميان تمام سوخت هاي مورد استفاده داشته است. كاهش قابل توجه تا 32/37 ٪ در كدورت دود مخلوط بيوديزل پيدا شد. اين مطالعه نشان داد كه 10٪ تركيب بيوديزل مي تواند به طور موثر در يك موتور ديزل اصلاح نشده استفاده شود.
