“…These models provide an approximation to correlate the factors to the responses. 28,30 Due to the fact that the electronic injector is a complex component involving multi-energy categories and multi-disciplinary fields, there is an interaction between parameters in different fields for the injector. 29 Therefore, this paper adopts the second-order polynomial response surface model, and the form of its approximation to the actual response y is as follows:…”

“…In order to perform significance analysis on fuel injection quantity and the related parameters, combining D-optimal design of experiment and partial least squares regression, an RSM model for fuel injection quantity prediction was obtained. 29 In Rajamohan et al, 30 RSM tool was applied in the process of optimizing the operating parameters of the test engine. As far as the predictive capacity of the established approximation model, it is often demonstrated by R-squared ( R 2 ), adjusted R-squared ( R adj 2 ), and root mean square error (RMSE).…”

The improvement of injector performance is important for the operation of common rail (CR) fuel systems. In this study, the optimization work has been carried out on a large-flow common rail injector. First, to simulate the injection process, a one-dimensional (1-D) model was developed and validated against the experimental data. The mathematical approximation model was also established to correlate the injection performance with the factors. Then, a multi-objective model by taking three design objectives into account was established and solved. Finally, Pareto front was obtained and the final optimization solution was determined. Furthermore, an extensive validation and analysis for the optimized results under various operating conditions was also carried out. Results shows that the three objectives, total response time, injection pressure fluctuation and injection pressure drop respectively, are improved by 11.75%, 39.12%, and 10.03% under the typical condition. And the proposed multi-objective optimization program based on design of experiment (DOE) technique, response surface methodology (RSM) and Elitist Non-dominated sorting genetic algorithm (NSGA-II) in present work can exhibit a good capability to optimize the problem of the injection performance in a CR fuel system.

“…Additionally, the impact of testing conditions does not promote the dissociation of nitrogen molecules into N atoms or facilitate the reaction between oxygen and N atoms to generate NO x emissions. (Rajamohan et al, 2022). Moreover, the emission of NO x is significantly influenced by multiple variables, including the chemical properties of the fuels, the adiabatic flame temperature, the ignition delay time, the injection timing, the combustion chamber geometry (relating to flame propagation velocity), the equivalence ratio, and the pressure (Dueso et al, 2018).…”

The present study reports on an investigation of teak sawdust pyrolysis oil blended with commercial diesel in a small four-stroke compression ignited engine. The engine performance and emissions were evaluated. The teak sawdust pyrolysis oil was obtained from a single-stage fixed bed pyrolysis reactor at 600 °C. Its physicochemical properties were characterized and found to be acceptable for the engine. Teak sawdust pyrolysis oil blends with diesel at the ratios of 10%, 25%, and 50% by mass were utilized. The small engine was tested at constant speeds from 800 to 2600 r/min. 25% teak sawdust pyrolysis oil blend at 2000 r/min was found to have better brake thermal efficiency with lower brake-specific fuel consumption compared to the other teak sawdust pyrolysis oil blends. Meanwhile, the highest engine load was obtained at 50% teak sawdust pyrolysis oil blend and 2600 r/min to be 8 kW. Furthermore, the emissions of CO, CO2, and hydrocarbon at 50% teak sawdust pyrolysis oil and 2000 r/min were slightly lower than other teak sawdust pyrolysis oil blends, no NOx detection in tested fuels, moreover, at 2600 speed, the smoke opacities of the fuels show lower than those the others. It was noted that a blend of 25% teak sawdust pyrolysis oil with diesel was suitable for the small engine (at 2000 r/min) in terms of performance and CO, CO2, and NOX emission for sustainability in agriculture and rural areas.
