In this present study, a CRDI (Common Rail Direct Injection) CI (Compression Ignition) engine operating in RCCI (reactivity Controlled compression ignition) mode was experimentally investigated to evaluate the effect of varying hydrogen share (HS) on engine performance and emission characteristics. The engine is tested under part load settings of 2.7 kW with fixed Fuel Induce timing (FIT) of 20˚bTDC while HS changed from 15% to 75% in increments of 15%. According to the experimental findings, varying HS increases the combustion's homogeneity and stability, leading to an improved engine power output. Brake thermal efficiency (BTE) likewise rises by 3.1% under diesel-hydrogen strategy than biodiesel-hydrogen at HS 60%. The results indicate that at 75% hydrogen share, HC and CO emissions were reduced by 22.58% and 11.51%, respectively. This study also demonstrates the possibility of using hydrogen to run the engine with a very lean combustion.
