| Article Name : | | | EMISSION ANALYSIS OF DI-DIESEL ENGINE AT DIFFERENT INJECTION PRESSURES USING JATROPHA AND RUBBER SEED OIL BLENDED WITH DIESEL | | Author Name : | | | S. Mahalingam , B. R. RameshBapu | | Publisher : | | | Ashok Yakkaldevi | | Article Series No. : | | | GRT-3495 | | Article URL : | |  | Author Profile View PDF In browser | | Abstract : | | | Biodiesel as a renewable fuel has been considered as the best alternate for diesel fuel now a days.This fossil fuel can be used in diesel engine with or without any modi?cation.The injection pressure and injection timing are the major influencing parameters forthe performance and emission of diesel engine.In thispresentstudy,the emission analysis of vegetable oil, Jatropha oil and rubber seed oil crushed from the seed, esterified and blended with pure diesel fuel. A single cylinder constant speed direct injection (DI) diesel engine has been used to analyze the emission characteristics of biodiesel.The diesel engine for various fuel injection pressures (210,220 and 240 bar) at no load to full load wasinvestigated. The injection pressure was changed in the engine head by adjusting the fuel injector spring tension. The two proportions of biodiesel were used in diesel engine such as 20% of biodiesel (Jatropha oil and Rubber seed oil) with 80% of pure diesel fuel named as B20 and 40% of biodiesel with 60% of pure diesel fuel named as B40.From the test result,the nitric oxide (NOx) was analyzed for different injection pressures. In emission characteristicsanalysis, it was found that the increase in injector opening pressure increases the NOxemission. The injection pressure of 240 bar and B20 proportion gives better emission reduction compared to other blended fuels. | | Keywords : | | |
