“…Pankaj Dubey et al 36 found an abate in brake thermal efficiency due to high viscosity and low volatility while using the dua fuel blend of turpentine and Jatropha oil biodiesel in the CI engine. Manikandaraja Gurusamy et al 37 found an escalation in thermal efficiency while increasing the low viscous camphor oil in the binary blend of cottonseed and camphor oil. V. Karthickeyan et al 38 also stated the negative correlation between kinematic viscosity and BTE while using Pistacia khinjuk biodiesel in CI engine.…”

This article studied the effect of blending low‐viscous Pinus oil with high‐viscous Millettia Pinnata oil on CI engine characteristics. The three blends of a combination of Pinus oil and Millettia Pinnata oil (P70K30, P50K50, and P30K70) were tested in a single‐cylinder water‐cooled computerized diesel engine coupled with an eddy current dynamometer by varying the load from 0% to 100%. The performance result establishes a positive correlation between BTE and the amount of Pinus oil in the blended fuel. Among the tested biofuel samples, P70K30 has the highest brake thermal efficiency of 29.73% but is 4.8% lower than diesel. At full load, the BSFC and BSEC of P70K30 show a 7.4% and 8.6% drop compared to diesel fuel but are higher than P50K50 and P30K70. Among the tested biofuel samples, a maximum in‐cylinder pressure of 70.96 bar was observed for P70K30, which is higher than P50K50 and P30K70 but lower than diesel. The net heat release rate and rate of pressure rise were found to be 48.26 J/oCA and 5.57 bar/oCA for P70K30, the highest among all tested conditions. Cycle‐to‐cycle variations were studied by calculating the standard deviation, range, and coefficient of variation for the in‐cylinder peak pressure of 100 cycles. The P70K30 has a coefficient of variation of 1.24%, which is higher than the P50K50 and P30K70 but lower than diesel. The P‐v diagram concludes that the three tested biofuels have strong thermodynamic properties since they have a good expansion rate and a pattern similar to diesel fuel. The emissions results show that increasing the amount of Pinus oil in blended fuel increases the NOx to 1410 ppm emissions and decreases the CO to 0.18%, HC to 44 ppm, and smoke to 76.6%.

“…The combustion temperature, pressure, oxygen and time determine NOx generation in CI engine. 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.…”

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.

“…Further, it reduces the EGT, combustion durations, CO, HC, and smoke emissions with negative effect in NO emissions”, as noted by Kasiraman et al [ 38 ] Manikandaraja and Chandrasekaran [ 39 ] manifested that equally blended camphor oil–diesel, turpentine–diesel, and lemongrass oil–diesel show better performance in water‐cooled 1‐cylinder CI engines than equally blended Karanja oil–diesel and mahua oil‐blended diesel fuel. Highlighting the significant fuel properties of camphor oil and cottonseed oil, Manikandaraja et al [ 40 ] disclosed the influence of camphor oil blending in cottonseed oil; their findings confirmed the reduction of CO, HC, and smoke emissions.…”

This article aims to study the impact of camphor oil premixing with intake air on compression ignition (CI) engine characteristics powered with jatropha oil and cottonseed oil. The experiment is conducted on the direct injection compression engine attached to the premixing setup. The investigation reveals that premixing of camphor oil with cottonseed oil and jatropha oil escalates the thermal brake efficiency to 35.02% and 33.62% and brings down the brake‐specific energy consumption to 10.27 and 10.70 kJ kWh−1. At all loading conditions, the premixing of camphor oil and the rise of camphor oil in premixing proportions increase the volumetric efficiency and cut the exhaust gas temperature. 20% premixing of camphor oil with cottonseed oil and jatropha oil drops the smoke opacity emissions by 22.23% and 11.86% and NO emission by 23.27% and 14.59%, respectively, at full load conditions. Further, it shows a 27.60% and 21.14% hike in CO emissions and a 31.34% and 31.87% hike in HC emissions at full load conditions. The in‐cylinder pressure, heat release rate, and mean gas temperature increase with increasing the energy share of camphor oil in premixing. Overall, the premixing of camphor oil shows better CI engine attributes except HC and CO emissions.
