Evaluation of C.I Engine Performance and Emission Characteristics Fueled with Cng and Ethanol Blends as Alternative Fuel
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 8
Abstract
Environmental air pollution and global warming are alarming concern world wide. Increasing air pollution, rapid growth of industrialisation and the global trend of urbanisation have totally disturbed the eco balance of resources on earth. These present study was done to visualize the potential of ethanol blends and CNG as an alternative fuel in C.I engine. The effect of ethanol on brake thermal efficiency, brake specific fuel consumption, characteristics for single-fuel and dual-fuel (CNG- diesel blends with ethanol) was investigated. The experimental setup consist of single cylinder four stroke engine using 3Kw diesel engine generator, with compression ratio of 16.5:1 and injection pressure of 240bar. The tests were performed at engine speed ranges from 1500 rpm at different loads with 10% CNG and 90% air and with mixtures of E10%, E15%, E20%, E25%, E27%, E30 and E50% in diesel fuel blends. The overall engine performance parameters include brake power, specific fuel consumption and brake thermal efficiency are calculated and compared with conventional diesel engine performance by plotting graphs.
