Hydrogen enrichment significantly impacts the performance and emissions of a Common Rail Direct Injection (CRDI) diesel engine using a diesel-Pongamia Pinnata biodiesel blend (B20). Hydrogen, introduced at flow rates of 7 lpm, 10 lpm, and varying load conditions (60%, 80%, and 100%), enhances engine efficiency due to its high calorific value. It reduces harmful emissions like CO and HC while improving brake thermal efficiency (BTE) and brake-specific energy consumption (BSEC). At 80% load, the B20+7H2 blend achieves an18.52% reduction in BSEC, along with lower emissions of HC and CO by 32.28 and 27.2%, respectively. These results demonstrate hydrogen's potential for cleaner, efficient diesel engine operation.
