“…Wider flammability and a higher flame due to hydrogen present in MSBD enhance the combustion and lower the CO emission . Further, H 2 induction lowers the mixture’s carbon content and stimulates quicker oxidation of CO to CO 2 , hence reducing CO emission. , The experiments carried out by different studies ,− demonstrate a similar finding of reducing CO emissions.…”

“…H 2 induction raises the air velocity, reducing fuel wall wetting, improved optimization of fuel, and lower HC. 16 HC emission lowers linearly with higher H 2 induction. The H 2 mixture has higher flammability, higher diffusivity, and higher flame speed which enhances the combustion and lowers the HC emission.…”

This study aims to examine the ignition pattern of CI engines run by nonedible mango seed biodiesel (MSBD). This work is also aimed to improve the ignition pattern of diesel engines by inducing hydrogen as a dual fuel in the intake manifold at various mass flow rates of 5 and 10 L per minute (lpm). Various parameters were calculated with varying intake hydrogen rates with MSBD and compared with diesel. Results concluded that the hydrogen supply at 10 lpm improved peak pressure by 3.22 bar, heat release rate (HRR) by 5.47 J/°C A, and brake thermal efficiency (BTE) by 3.4% of MSBD. Further, hydrogen supply also reduced overall HC by 0.36 g/ kWh, CO by 3.9 g/kWh, and smoke emission by 3.8 Bosch smoke unit (BSU) at all brake mean effective pressures (BMEPs) from neat MSBD with a 3.3 g/kWh increase in NO. Further, this research work reveals that hydrogen addition at 10 lpm with MSBD shall improve the ignition patterns of a diesel engine.

The current research focuses on the impacts of pine oil injection and hydrogen induction separately with hemp oil methyl ester (HOME) in the single cylinder diesel engine in dual fuel‐reactivity controlled compression ignition (DF‐RCCI) combustion mode. The engine was tested under a DF‐RCCI mode for the different energy shares of 10% pine oil with HOME (10P‐HOME), 30% pine oil with HOME (30P‐HOME), 3‐lpm hydrogen with HOME (3‐lpmH2‐HOME), and 6‐lpm hydrogen with HOME (6‐lpmH2‐HOME) separately at 345 °CA bTDC of low reactivity fuel (pine oil and hydrogen) and 23°C bTDC injection timing of high reactivity fuel (HOME). The results showed a higher Brake Thermal Efficiency (BTE) of 7.44%, 5.32%, 5.72%, and 2.46% for 6‐lpmH2‐HOME, 3‐lpmH2‐HOME, 30P‐HOME, and 10P‐HOME fuel shares, respectively, over the conventional diesel combustion (CDC) at full load. 30P‐HOME, 3‐lpmH2‐HOME, and 6‐lpmH2‐HOME fuel combinations recorded 4.08% 4.42%, and 5.69% lower brake specific fuel consumption (BSFC), respectively, at full load. When comparing DF‐RCCI combustion to CDC, an increase in the heat release rate (HRR) of 2.89%–26.50% and a rise in peak cylinder pressure of 0.77%–12.99% were observed. The 30P‐HOME, 3‐lpmH2‐HOME, and 6‐lpmH2‐HOME emit less smoke in DF‐RCCI combustion mode by 13.06%, 4.84%, and 7.26%, respectively at full load condition. When using 30P‐HOME the exhaust gas temperature (EGT) decreased by 3.50% at full load condition. At part and full load conditions, the 30P‐HOME fuel share reduced oxides of nitrogen (NOX) emissions by 3.93% and 5.26%, respectively.
