Renewable energy research in support of the generously developing choice for diesel fuel automobiles has been concentrated because of environmental causes and hurly burly into petroleum combat. The test has been conducted in a light-duty single cylinder variable compression ratio (VCR) naturally aspirated multifuel research engine. Three input parameters, compression ratio (CR), injection pressure (IP), and injection timing (IT), are taken as input amends. In this study parameters are taken as 16, 17, and 18 for CR and 210 bar, 230 bar, and 250 bar for IP and 21°, 23°, and 25° before top dead center (bTDC) for IT. Experimental trials have been planned via statistical tool like design of experiments (DoE) to outline the resulting output, such as performance and emission. Better performance and lesser exhaust pollution are the desirable output factors by optimizing the injection system and compression ratio parameters by factorial design. The confirmatory tests validated that the models developed using response surface methodology (RSM) are adequate to describe the effects of CR, IP, and IT on the performance and emission characteristics using all test fuels. The error in prediction using RSM is within 5%.

“…It can be seen that the vapor and liquid phase penetration distances of the three fuels increase with the increase in IP. This is because when the IP increases, the pressure difference between the inside and outside of the nozzle increases, and the initial kinetic energy of the oil droplets becomes higher [45]. This increased kinetic energy makes the spray penetrate to a longer distance.…”

Polyoxymethylene dimethyl ether (PODE) is a low-viscosity oxygenated fuel that can improve the volatility of blended fuels. In this work, the macroscopic and microscopic spray characteristics of diesel-PODE3-4 under different ambient temperatures and injection pressures (IP) are studied. The studied blends consisted of pure diesel (P0), two diesel blend fuels of 20% (P20) and 50% (P50) by volume fraction of PODE3-4. The Mie scattering and Schlieren imaging techniques are used in the experiment. The results show that with the increase in IP, the vapor phase penetration distance and the average cone angle of the three fuels increased, and the Sauter mean diameter (SMD) of the three fuels decreased. When the ambient temperature increased, the vapor phase projection area and the average vapor phase cone angle of P20 and P50 increased, and the SMD decreased, but the vapor phase projection area of pure diesel did not change significantly. The results indicate that the blended fuel with PODE3-4 has better spray characteristics than P0 at low temperature, and the SMD hierarchy between the three fuels is P0 > P20 > P50. Through the visualization experiment, it is helpful to further understand the evaporation characteristics of different fuel properties and develop appropriate alternative diesel fuel.

“…Generally, the results suggest that the design contemplated is both feasible and beneficial compared to conventional tubular reactor designs. Kim et al (2015) described spray and atomization characteristics, at macroscopic and microscopic levels, of isobutene blended DME fuels, using a spray visualization and droplet particle analytical system. In combustion engine systems, the fuel spray characteristics and atomization performance play an essential role in the improvement of exhaust emissions and combustion characteristics in automotive engines.…”
