Performance and emission optimization of a CRDI engine in RCCI mode using hydrogen enriched biodiesel through grey relational analysis approach.

ABSTRACT: This study investigates the performance and emission optimization of a Common Rail Direct Injection (CRDI) diesel engine operated in Reactivity Controlled Compression Ignition (RCCI) mode using alternative fuel strategies. Experiments were performed on a single-cylinder, four-stroke, water-cooled CRDI engine operating at a constant speed of 1500 rpm under 25%, 50%, 75%, and 100% load conditions, corresponding to a brake mean effective pressure (BMEP) range of 0.4-1.6 MPa. The test environment was maintained at an ambient temperature of 29 ± 2 °C, relative humidity of 68 ± 5%, and atmospheric pressure of 1.01 bar. The intake manifold pressure was regulated at 1.0 ± 0.02 bar, with coolant and lubricating oil temperatures stabilized at 80 ± 2 °C and 85 ± 3 °C, respectively, to ensure consiste
