“…As seen in the figure, SMD decreased as the injection pressure increased, and increased as the ambient pressure increased. This is consistent with the literature data [66,67]. Biodiesel fuels had, on average, around 47% higher SMD values than that of fossil-based diesel.…”

In contrast, ethanol is produced from biogenic resources like maize, sugarcane, etc. Thus, biodiesel can be fully renewable if ethanol is used instead of methanol in the biodiesel production process.Besides, ethyl esters have extra advantages over methyl esters such that they can have better performances in cold weather. However, studies considering the characteristics of ethyl esters are limited in the literature, and these papers have fully focused on performance and emission characteristics. Any published paper investigating the spray characteristics of ethyl esters is not yet available. This paper brings a certain novelty by investigating the spray characteristics of various ethyl ester type biodiesels.

“…issue that needs attention. Very high injection pressures can have the possibility of wall impingement in diesel engines causing an increase in fuel consumption as well as HC and PM emissions [66,67]. Furthermore, spray penetration curves could be divided into two phases which were the rapid development phase and steady development phase.…”

“…Similarly, Bhikuning et al 11 conducted experiments on spray characteristics of WCO, bio hydro fined diesel (BHD) oil, and n‐tridecane in constant volume chamber under evaporating and nonevaporating conditions and concluded that spray tip penetration of WCO was higher than BHD oil and n‐tridecane under both conditions due to high‐rheological property. Similar studies were also done by researchers 12,13 and found that biodiesel exhibited longer penetration and larger sauter mean diameter (SMD) than diesel and there was reduction in spray tip penetration with the increase in ambient pressure, while increases linearly as injection pressure raises at primary breakup stage. However, the reduction in penetration occurred at high‐ambient temperature.…”

“…20,21 However, the trend of ultra-high injection pressure and micro-hole nozzle diameter causes wall impingement, which leads to an increase in HC, particulate, and BSFC. 12 Pressure-swirl atomizer is broadly used in various fields, such as aircraft air combustors, industrial furnaces, and DISI engine but liquid jet breakup process is crucial stage in combustion. The excellence of the liquid jet breakup process takes a leading role in overall performance, flame stability, and emissions, since it controls fuel distribution and droplet size.…”

Atomization characteristics and evaporation have major role in air‐fuel mixing and the combustion process in diesel engine. The aim of this study is to perform numerical and experimental analysis to investigate the spray pattern of biodiesel (waste cooking oil) generated from pressure swirl atomizer. The computation exhibits Eularian‐Lagrangian method to comprise flow of multiphase and also linearized instability sheet atomization (LISA) model to envisage atomization, sheet breakup, and film formation. The model's strength is the identification structure of spray created from pressure swirl atomizer. A three‐dimensional computational fluid dynamics work consisting of LISA and Taylor analogy breakup model are certified via experimentation taken from constant volume chamber. Further, spray tip penetration, cone angle, and sauter mean diameter (SMD) are identified for fuel (B100, B25, and D) under injection pressure of 110 and 160 MPa, and 2.8 MPa ambient pressure using swirl atomizer in constant volume chamber. This particular spray is quite important for application in diesel engines but is not extensively explored. The results reveal that as injection pressure increases from 110 MPa to 160 MPa. The spray tip penetration for B100, B25, and D are increased by 19.86%, 14.90%, and 14.50% respectively, further, cone angle at the start of injection decreases by 6%, 5%, and 3.41%, similarly, the average SMD decreases by 25%, 33.33%, and 25.4%, respectively. This is due to the rheological property of fuel, turbulent energy of droplet and air is maximum in primary breakup zone.

“…FIP, fuel injection percentage; HC, hydrocarbon; IP, injection pressure; SOMI, start of main injection; SOPI, start of pilot injection quality, which provides shorter ignition delays and complete combustion. 30 Also, an increase in the FIP in the pilot period from 10% to 20% slightly decreases the CO formation, which suddenly increases with a further rise in pilot fuel quantity to 30%. The reason for the same was that the rise in the amount of pilot percentage does not properly get mixed with air and does not get combust.…”

Limited fuel capacity and pollution are major concerns in the automobile industry. The combustion, performance, and emission characteristics are important considering the engine's overall performance. In the present paper, an experimental investigation was carried out on a small diesel engine to analyze the effect of injection system parameters on all measurable characteristics. The conventional diesel engine injection system was retrofitted with a common rail diesel injection (CRDI) system. The injection system parameters such as injection pressure, start of pilot injection timing, the start of main injection timing, and quantity of fuel injection percentage during the pilot and the main injection period were considered in the study. With the use of the CRDI system, it was observed that mean effective pressure and cylinder pressure were increased compared to the conventional diesel engine. There was a decrease in the peak value of the HRR and RoPR curve and simultaneously an increase in the width of the curve. MGT inside the combustion cylinder was also decreased. The retrofitted CRDI system shows higher thermal efficiency with good fuel economy as well as found a considerable reduction in carbon monoxide (CO) and smoke percentage. Overall, the considered injection system parameters deliver a significant improvement to the overall attributes of the small diesel engine.
