Effects on the Performance Characteristics by Altering Different Parameters for Single Cylinder C.I. Engine Blended with Neem Bio-Diesel

摘要

This study specially focuses to alter different parameters instead to change design of parts. Experiments carried out on 10 H.P. single cylinder C.I. Engine which normally used by farmers for irrigation purpose. Trial was carried out by altering parameters like no. of nozzle holes and injection pressure with different proportion of Neem Bio-diesel blends. While using such Bio-Fuel blends, lethal emissions were also recorded during each trial to predict emission characteristics and performance. Due to fluid characteristics of bio fuel it needs comparatively different conditions to atomize properly. So as by changing injection pressure and number of hole in nozzle may affect the performance and emission characteristics. Result shows excellent Break Specific Fuel Consumption (BSFC), Break Specific Energy Consumption (BSEC), Break Thermal Efficiency (BTE), and Mechanical Efficiency (ME) at 240 bar injection pressure. While excellent Indicated Thermal Efficiency (ITE) at 220 bar pressure. It was also seen that 3 and 4 hole nozzle pays higher performance at 240 bar pressure. At 220 bar injection pressure, it was clearly seen that 4 and 5 hole nozzle were excellent to atomize the fuel. Reduction of lethal emissions were recorded excellent during 4 hole nozzle with 220 bar pressure and 5 hole nozzle with 240 bar pressure.
