Abstract: In this study the experimental attempt was carried out to investigate the performance, combustion and emissions by changing the various nozzle holes size of the injector such as (3 hole x Ø0.28 mm), (3 hole x Ø 0.30 mm), (4 hole x Ø 0.28 mm), (4 hole x Ø 0.30 mm), (5 hole x Ø 0.28 mm), (5 hole x Ø 03.0 mm). The experiments are performed on Kirloskar 4- stroke single cylinder direct injection diesel engine fueled with diesel and rubber seed oil methyl ester (RSOME) at 1500 rpm, and coupled with electrical dynamometer with the standard injection timing of 23.4° bTDC (before top dead centre) with an injection pressure of 240 bar kept up invariant throughout the experimental diesel and RSOME work. It is found that Ø 0.28 mm nozzle hole diameter 4 hole gives higher brake thermal efficiency, lower specific fuel consumption, Carbon monooxide, HC, for Diesel and RSOME compared with other nozzle geometry conditions.
