Abstract
ABSTRACT The intention of the current experimental analysis was for the assessment of combustion and vibration using a direct injection single cylinder compression ignition engine. The tests were performed at different loads of 25%, 50%, 75%, and 100% separately with the Moringa oleifera-diesel mixed test fuels samples such as; B0D100, B10D90, B20D80, and B30D70. The parameters concerning combustion i.e. cylinder pressure (CP) and net heat release rate (NHRR) of the diesel engine was improved somewhat while fuelling with M. oleifera biodiesel blends compared to conventional diesel. Besides, the engine vibrations were brought down for biodiesel usage rather than regular diesel. The improvement in combustion and vibration was observed at higher loads. B20D80 was shown best the outcome than the remaining fuel samples. At 100% load, the peak values of CP and NHRR intended for B20D80 were enhanced by 2.91% and 9.5%, while the RMS velocity (vibration) was lowered by 14.27%.
