PERFORMANCE OF DUAL-FUEL (DF) ENGINE POWERED WITH THE PRODUCER GAS DERIVED FROM SUGAR CANE BAGASSE AND DIESEL INJECTION

摘要

Renewable and sustainable fuel usage in diesel engines ensures energysecurity and overseas exchange savings besides conveying both socioeconomicand environmental concerns. This research presents experimentalwork that has been done on single-cylinder, 4-stroke, diesel engine of directinjection run in DF mode using PG derived from sugar cane bagasserenewable and sustainable fuels. A 45° gas venture is designed and developedto provide a stoichiometric mixture of gas and air entry into the intake manifoldof the DF engine during suction stroke. A compressed mixture of air and gasis ignited by injecting diesel into the engine cylinder at 205 bar pressure and atdifferent timings of injection. The effect of timing of injection on the DF engineperformance is studied by varying it from 23 to 31obtdc in steps of 4obtdc.Experimental investigation showed that 27oBTC resulted in improved BTE withreduced emissions of hydrocarbon, smoke, and CO while NOx, peak pressureincreased. It is noticed that the operation of producer gas lowers the power deratingby 20 and the DF engine could run up to 80 load with increased nitricoxide (NOx) emissions. The developed DF engine worked satisfactorily withacceptable performance and emission norms and assisted in partiallysubstituting the fossil diesel fuel with a substitution of 60-70 by the PGoperation.
