Effect of Injection Pressure and Nozzle Hole Diameter on Combustion Parameters of CI Engine Fuelled with B20 Neem Blend

摘要

In the present study an experimental work had been carried out to analyze the combustion parameters of B20 neem blend by varying injection pressure and nozzle hole diameter. The engine tests are conducted on kirloskar 4- stroke single cylinder 1500 rpm water cooled direct injection diesel engine with eddy current dynamometer with standard injection timing 23?bTDC was maintained constant throughout the experiment. 3 different injection pressures such as 210 bar, 230 bar, 250 bar and 3 different nozzles such as (3×0.28mm), (4×0.23mm), (5×0.20mm) varied to analyze the combustion parameters. From the test results, it could be observed that among 3 different nozzles (3×0.28mm) nozzle gives higher Peak pressure rise as compared to 4 hole nozzle and 5 hole nozzle.
