“…Butanol in P20Bu5D75 and P20Bu10D70 produce healthier flame propagation, mixture, and atomization, leading to lower HC emissions than PDME20 and diesel. 35 Similar results in HC emissions were observed from work made by Devarajan et al 17 , Devarajan et al 12 and Aurtherson et al 13 HC emissions at 100% load for PDME20, P20Bu5D75, P20Bu10D70 and diesel are 46, 44, 42 and 53 PPM correspondingly.…”

“…CO for P20Bu5D75, P20Bu10D70, and PDME20 is lower than diesel under all circumstances. CO emission formation relies on Oxygen content, Cetane number, viscosity and density 35 . Lower O 2 is the key motive for higher CO emissions for diesel than PDME20, P20Bu5D75, and P20Bu10D70.…”

“…NO for P20Bu5D75, P20Bu10D70 is lower than PDME20 and diesel under all circumstances. Biofuels produce higher latent heat of evaporation and lower energy content, reducing the combustion phase, duration, and NO emissions 35 . This is due to lower energy content and higher latent heat of evaporation of additives, which slows down the combustion process and reduces the peak cylinder pressure and combustion temperature 36 .…”

The chief objective of this study is to utilize non‐edible, carbon‐rich oil derived from Prunus domestica seeds as blended fuel. The combustion efficiency of derived blends shall further be enhanced by blending higher alcohol into biodiesel/diesel blends. This work details the impact of effectively utilizing waste and non‐edible oil to replace fossil fuels partially. In this study, the P. domestica is trans‐esterified to methyl ester and blended with diesel at 20%. Further to enhance the ignition nature, butanol, higher alcohol, is blended to P. domestica biodiesel/diesel blends at 5% and 10%. The ignition pattern of the modified fuels is extensively studied and compared with diesel in a stationary research diesel engine. This study involves four fuel samples, namely, neat P. domestica methyl ester and is termed PDME. 20% of PDME is blended with 80% diesel is referred to as PDME20. 20% of PDME with 5% n‐butanol and 75% diesel is termed PDME20Bu5D75, 20% of PDME with 10% n‐butanol and 70% diesel is termed as PDME20Bu10D70 and diesel. Addition of PDME and butanol at different blends found miscible with diesel. PDME and butanol provided a suitable time for reaction and mixing, complete combustion, higher O2 content, and rich fuel‐air mixture, resulting in lower emissions than diesel. Further, butanol aided better atomization, effective combustion and resulted in higher efficiency with lower fuel consumption. Adding butanol also lowered the viscosity and improved the mixing process, and produced better in‐cylinder pressure and heat release rate.

“…The idea of using biodiesel, biogas and hydrogen/HHO gas as a fuel has gained interest among researchers over the decades. Many works have focused on employing biodiesel, biogas and hydrogen/HHO gas as fuel in modified engines 2–6 . Devarajan et al, 7 used hydrogen gas in a CI engine running in dual fuel mode with biodiesel as the fuel and air preheated before being fed to the engine.…”

Carbon emission and problems associated with the world have been the major concerns for the past few decades. The world governments have implemented stringent emission norms to reduce the pollution created by hydrocarbon combustion in automobiles. The use of gaseous fuels in IC engines has gained interest among the research community. In the present research work, hydrogen, and oxygen (HHO gas) are produced together in an electrolyzer unit and is fed into the engine intake manifold before the carburetor. The electrolyzer consists of an anode, cathode and five neutral plates made of 316 L SS. Electrolyser production rate was tested with four different molarity conditions of NaOH electrolyte solution ranging from 0.24 to 1 N. It was noted that a maximum of 2 LPM of HHO gas was produced with the supply of 90 A‐h current at 1 N solution concentration. The performance and emission characters of the SI engine were conducted at six different load conditions and four flow rates of HHO gas. HHO gas induction has significantly increased the thermal brake efficiency by 8% and decreased the specific fuel consumption by 20%. With the supply of 2 LPM of HHO gas, CO2, HC, and NOx emissions were reduced by 67%, 59%, and 34%, respectively.
