“…Different studies listed in the literature have discussed in the next lines. The effects of injection timings as well as split injection on characteristics of a diesel engine powered by cashew nut shell biodiesel blends are experimentally investigated by (Senthil kumar and Thirumalini 2020). Smoke is reduced by 19.5%, 73.8% for diesel and B5 respectively at 4° retarded CA and 15% split.…”

Great attention is directed towards the study of the spray phenomena theoretically and experimentally due to its dramatic effect on the combustion process that occurred in an internal combustion engine, in particular, the diesel engine. The spray macroscopic characteristic of diesel engines fueled with two different biodiesel fuels in addition to nominal diesel under various injection pressures has been investigated numerically in this work. The selected biofuels are Rapeseed methyl ester (RME), Waste cooking oil methyl ester (WCOME). The Russian simulation software Diesel-RK is used in this work. Four different injection pressures are used which are 200, 500, 800 and 1000 bar respectively. It is found that RME has higher spray penetration with a narrow spray angle due to high viscosity and large momentum compared to diesel fuel. The results reported that biodiesels have greater Sauter mean diameter (SMD) compared to pure diesel because of their higher viscosity and surface tension. Promising reduction in SMD comes with WCOME as the injection pressure increases. Cylinder pressure along with heat release is reduced in the case of biodiesel due to the reduction in heating values. The lowest ability to produce smoke is recorded for WCOME where 93% reduction is achieved followed by a 57% reduction for RME as compared to diesel. The obtained results are compared with the results of other researcher and the convergence between them is observed.

“…The second-order polynomial equations for HC are given in the Figure 6 highlights the variations of CO2 emission and brake power. The product of the hydrocarbon fuel itself is carbon dioxide which measures the successful oxidation of the carbon atoms (Ashok et al 2018;Liang et al 2020;Senthil and Thirumalini 2020). Therefore, the fuel with higher oxygen content can produce more amount of carbon dioxide.…”

“…The mixing of camphor oil with Karanja oil suppress the effects of viscosity of Karanja oil. But on the other hand, the addition of camphor oil supported proper oxidation of diesel by supplying the additional oxygen (Ashok et al 2018;Liang et al 2020;Senthil and Thirumalini 2020). The second-order polynomial equations for CO2 are given in the table.…”

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%.

“…In comparison with diesel fuel, tailpipe discharge, such as HC, CO, and smoke, were found to be decreased by 12.16%, 32.14%, and 19.71%, respectively. Senthil Kumar et al [13] examined the effects of pilot-injection quantities (5%, 10%, 15%) and retarded injection (2 • CA and 4 • CA) in a common rail direct-injection engine with cashew-nutshell (CNSL) biodiesel blends. The CNSL biodiesel blend reduced the NOx, smoke, and carbon monoxide emissions, in addition to increasing the hydrocarbon emissions.…”

Pilot-fueling and nozzle-injection pressure are significant injection parameters, and they have significant impacts on modern vehicles for enhancing the engine output, in addition to meeting rigorous tailpipe-exhaust emission standards. In this current work, the influence of the pilot-fueling pressure and nozzle-opening pressure (NOP) on the engine performance and tailpipe outcomes from a compression-ignition (CI) engine at a higher injection pressure and varying load conditions was investigated using a waste cooking oil (WCO) biodiesel (B20). The experiments were executed in a high-pressure CRDi-fitted diesel engine at the start of pilot fueling (SOPF) (timing: 23° bTDC), and at the start of the main fueling (SOMF) (timing: 33° bTDC). The results showed that the combined influence of the pilot-fueling and nozzle-opening pressure induced a remarkable enhancement in the BTE, by 25.13%, and the BSFC decreased by 13.88%, compared with diesel at 10% pilot fueling. Carbon monoxide, hydrocarbon, and smoke emissions were drastically reduced for the higher pilot-fueling quantity by 21.05%, 16.66%, and 33.10%, respectively, compared with the diesel at 10% pilot fueling. With the implementation of the pilot-fueling strategy, there is no effect on the NOx reduction.
