Anxiety of greenhouse gases and exigency of conventional fuels is an attractive exploration reneged to the researchers view, turn towards alternative fuels. The present work is to demonstrate on performance, combustion and emission characteristics of 20% Karanja Methyl Ester (KOME) blend (B20) and hydrogen with 5, 10, and 15 lpm (liters per Minute) of low flow rate on a dual fuel mode direct injection diesel engine operated at 1500 rpm with rated power output of 3.5 kW. The experimental test were conducted at three various injection operating pressure of 200, 220, and 240bar. The obtained data of above test were compared with base line pressure of diesel at 200 bars. Higher brake thermal efficiency, less brake specific fuel consumption, lower HC, and CO emissions with raised concentration of NOx were obtained at IOP of 240 bars for B20- hydrogen dual fuel mode. The current analysis discovered that the IOP of 240 bars for 15 lpm hydrogen flow rate with B20 dual fuel approach was optimum.
