“…27,28 The induction of hydrogen with increased heating value and flame temperature increases NO generation. 29,30 KOME + 10LPM had the highest NO emissions due to increased combustion chamber turbulence because hydrogen has six times higher heating value than diesel. Hydrogen's greater heating value and extra oxygen in biofuel raise in-cylinder temperature and pressure, which increases NO emission.…”

Kapok oil methyl ester (KOME) is used as a pilot fuel, while hydrogen and diethyl ether (DEE) are used as secondary fuels to improve the performance, emissions and combustion of a direct injection compression ignition engine. With a compression ignition engine, a slight modification to the system enables hydrogen gas through the intake manifold. A flow metre limits the quantity of energy the hydrogen may produce off, and two flame arresters prevent backfires in the fuel line. At full load and maximum hydrogen energy sharing, KOME + 20%DEE obtained a brake thermal efficiency of 30.31%, which is 14% higher than without hydrogen enrichment and about 8% higher than diesel's value (0% hydrogen energy share). The main problem with previous research is that hydrogen with a high heating value makes greater amounts of nitric oxide. Diethyl ether, on the other hand, has fixed this major problem, and the absence of carbon in hydrogen fuel lowers CO, HC and smoke emissions.

“…At full load conditions, the BTE increased by 31 to 36.5%, the HC and CO were reduced by 20% and 10%, respectively, while the NOx increased by 40%. A 10% exhaust gas recirculation (EGR) was utilized, which resulted in a 26% decrease in NOx emissions [13]. Scaldaferri and Pasa (2019) studied the effects of different parameters, such as temperature, pressure, and time, on the reactions occurring with CNSL, using a catalyst of 10% w/w palladium over activated charcoal.…”

Effect of Injection Parameters on the Performance of Compression Ignition Engine Powered with Jamun Seed and Cashew Nutshell B20 Biodiesel Blends

Renewable fuels are alternative resources that find use in the power generation, agricultural, and transportation sectors. The sustainable utility of these renewable fuels mostly addresses the socio-economic issues of a country and reduces its dependency on fossil fuels. In addition, being environmentally friendly allows them to handle global warming more effectively. Two B20 fuel blends were produced using methyl esters of cashew nutshell and jamun seed oils to test the performance of the common rail direct injection engine. To improve the engine performance, injection parameters such as nozzle geometry, injection time, and injector opening pressure are used. Improved brake thermal efficiency and lower emissions of smoke, hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) were achieved with the help of advancing the injection timing, raising the injector opening pressure, and increasing the number of injector nozzle holes. In addition to reducing the ignition delay, extending the combustion duration, and increasing the peak pressure, the revised injection settings also boosted the heat release rates. At the maximum load, compared to CHNOB B20, JAMNSOB B20 showed a significant rise in the brake thermal efficiency (BTE) by 4.94% and a considerable decrease in smoke emissions (0.8%) with an increase in NOx (1.45%), by varying the injection timing, injection pressure, and nozzle geometry of the common rail direct injection (CRDI) engine.

“…Accumulated NO x reduction reached 38.4% when 10% EGR rate was applied. Loganathan et al [39] indicated hydrogen addition in biofuel combined with EGR enhanced engine thermal efficiency and simultaneously reduced NO x emission. Thermal efficiency of hydrogen-enriched biofuel engine increased from 31.0% to 36.5% when compared to biofuel mode.…”
