“…Again, in terms of viscosity, the C30K70 has a lower thermal efficiency because of its enhanced viscous nature. High viscous fuels fail to prepare a proper air-fuel ratio due to the bigger size of the droplets and poor penetration of fuel particles into the high-pressure air, which produces lower thermal efficiency (Rakopoulos et al 2015;Kanth et al 2021;Narayanamoorthy et al 2021). The abovementioned phenomenon happened to C70K30.…”

This article compares the influence of the blending the low-viscous oxygenated camphor oil with hydrocarbon diesel fuel and high viscous oxygenated Karanja oil. The experiment is conducted in a four-stroke 1-cylinder naturally aspirated Kirloskar compression ignition (CI) engine coupled with an eddy current dynamometer. The three types of fuel blends are prepared by blending the camphor oil with Karanja oil on the volume ratio of 30:70 (C30K70), 50:50 (C50K50), and 70:30 (C70K30), and the other three types of fuels are prepared by blending the camphor oil with diesel on the volume ratio of 30:70 (C30D70), 50:50 (C50D50), and 70:30 (C70D30). The results reveal improvement in the engine performance characteristics of the brake thermal efficiency and brake specific energy consumptions due to the blending of camphor oil either with hydrocarbon diesel fuel or Karanja oil. Further, it also reduces the CO, HC, and smoke emissions with an increase in NO and CO2 emissions. The rate of pressure rise, net heat release rate and cyclic irregularities found to increase with increase in proportion of the camphor oil. The P-v diagram also confirms the lower heat addition period for the C70D30 and C70K30 with an increase in brake thermal efficiency. The actual compression ratio and the actual cut-off ratio are found to have a reasonable correlation with the thermal efficiency of the engine. Second-order polynomial equations were obtained for the engine characteristics using the Curve fitting method, and the characteristic equations confirmed the confidence level of 95%.

Experimental studies of laminar burning velocity and flame instabilities of 2,5-dimethylfuran (DMF) were conducted at different equivalence ratios (from 0.9 to 1.3), initial pressures (from 0.1 to 0.8 MPa), and initial temperatures (from 393 to 493 K) by the method of the schlieren and high-speed photography system in the constant-volume combustion bomb. The results showed that the laminar burning velocity of the DMF/air flame decreased with increasing initial pressure and increased with increasing initial temperature. The maximum laminar burning velocity occurred at φ = 1.1, regardless of the initial pressure and temperature conditions. The power law fitting of baric coefficients, thermal coefficients, and laminar burning velocity was obtained, and the laminar burning velocity of DMF/air flame can be predicted well in the study range. The diffusive-thermal instability of the DMF/air flame was more pronounced during rich combustion. Increasing the initial pressure increased both the diffusive-thermal instability and the hydrodynamic instability of the flame, while increasing the initial temperature increased the diffusive-thermal instability of the flame, which was mainly responsible for flame propagation. In addition, the Markstein length, density ratio, flame thickness, critical radius, acceleration index, and classification excess of the DMF/air flame were investigated. The results of this paper provide a theoretical support for the application of DMF in engineering.

“…Throughout the engine's life, carbon dioxide (CO 2 ) emissions could be reduced by fueling it with renewable biofuels. Currently, biofuels such as alcohols 25 , biodiesel, and furans 26 – 29 were used. n -Butanol has a lower vapor pressure and a higher flash point than methanol and ethanol, making it potentially safer to supply and use.…”

Reactivity controlled compression ignition (RCCI) engines have a high thermal efficiency as well as low emissions of soot and nitrogen oxides (NOx). However, there is a conflict between combustion stability and harmful emissions at high engine load. Therefore, this work presented a novel approach for regulating n-butanol/methyl oleate dual fuel RCCI at high engine load in attaining lower pollutant emissions while maintaining stable combustion and avoiding excessive in-cylinder pressure. The tests were conducted on a single cylinder engine under rated speed and 90% full load. In this study, n-butanol was selected as a low-reactivity fuel for port injection, and n-butanol/methyl oleate blended fuel was used for in-cylinder direct injection. Combustion and emission characteristics of the engine were first investigated with varied ratios of n-butanol port injection (PFI) and direct injection (DI). Results showed that as the ratio of n-butanol PFI and DI rose, the peak cylinder pressure and heat release rate increased, while NOx and soot emissions reduced, and carbon monoxide (CO) and hydrocarbon (HC) emissions increased under most test conditions. When RNBPI = 40% and RNBDI = 20%, the soot and NOx emissions of the engine were near the lowest values of all test conditions, yet the peak in-cylinder pressure and fuel consumption could not increase significantly. Therefore, the possibility of optimizing the combustion process and lowering emissions by adjusting the pilot injection strategy was investigated utilizing these fuel injection ratios. The results revealed that with an appropriate pilot injection ratio and interval, the peak in-cylinder pressure and NOx emission were definitely reduced, while soot, CO, and HC emissions did not significantly increase.
