“…Similarly, transesterification was implemented in [4], which provides increased accuracy with reduced percentage of uncertainty, but issues may arise in entire fuel atomization. Finally, early direct injection was proposed in [5], which offers minimized emission of HC and it also more time for injection, however, pressure may get raised due to changes in temperature. These above mentioned challenges should be taken into consideration for motivating the developments in the bio-diesel fuel blending engines.…”

Biodiesel is accessible in a number of diverse blends. It can be blended with petro-diesel or can be utilized as a fuel on its own. Hence, biogas run Dual Fuel Diesel Engines (DFDE) offer an attractive replacement for traditional diesel engines. Nevertheless, the biogas run DFDE are overwhelmed by the troubles of high emissions and low efficiency. Hence, this paper focuses on the issues related to conventional fuel diesels and has established a diesel oil blend with better efficiency. Moreover, a Self Adaptive Particle Swarm Optimization (SAPSO) is adopted to analyze the performance of engines and emissions. In addition, the proposed method is compared with Genetic Algorithm (GA) and PSO and the results are obtained.

A set of GDI system for ethanol injection is installed on a F188 diesel engine, and the diesel supply system of the original diesel engine is used for diesel injection. The computational fluid dynamics software FIRE is adopted to establish a 3D combustion model of the ethanol -diesel direct injection engine. The total heat energy of the fuel is equivalent to that of the original diesel engine under the same condition. As the diesel injection starting point is 344°CA and there is simultaneous diesel and ethanol injection, the ethanol injection starting points at 344°CA, 338°CA, 332°CA, 326°CA and 320°CA are subject to 3D simulation for fuel injection, mixed gas formation and combustion and pollutant formation process. The results show that, the earlier the ethanol injection is, the steeper the heat release rate curve during the initial combustion period, the higher the peak value, and the shorter the heat release duration are, and the higher the maximum combustion pressure, the headmost phase of the maximum combustion pressure and the more obvious the premixed combustion are. Earlier ethanol injection starting point and quicker rise of the temperature curve of the cylinder bring the headmost phase of the highest average temperature in the cylinder, and higher average temperature in the cylinder brings higher NO concentration. The ethanol injection starting point shall be earlier than the diesel injection starting point injection, for it is the most favorable for reducing soot generation.

“…As ethanol is not mutually soluble with diesel [4], its application in the diesel engine is difficult, therefore, a number of application forms including mixing [5,6], ethanol injection in the inlet or the cylinder ignited by burning diesel [7] and homogeneous charge ignition by compress combustion occur [8]. Fang Xianzhong, et al of Jilin University conducted the ethanol -diesel direct injection study before, with diesel injection and ethanol injection respectively for the new mechanical pump injection system and the original injection system.…”

Abstract. A set of GDI system was installed on a F188 single-cylinder, air-cooled and vertical direct injection diesel engine, which was used for ethanol injection, and the mechanical pump injection system of the original diesel engine was used for diesel injection. Ethanol and diesel account for half of the total size respectively, and the total heat energy of the fuel is equivalent to that of the original diesel engine under the same condition. A 3D combustion model is established for the ethanol -diesel direct injection engine. The ethanol injection is adopted with two-stage injection mode, with the first stage injection starting point at 240°CA and the second stage injection starting point the same as the diesel injection starting point, 344°CA. Four conditions featured by the same total two-stage ethanol injection and the first stage injection and second stage injection respectively accounting for 20% and 80% (B20L80), 40% and 60% (B40L60), 60% and 40% (B60L40) and 80% and 20% (B80L20) of the total injection are calculated and analyzed. After diesel burning, the mixed ethanol is ignited. The two-stage ethanol injection proportion is different, and ethanol premixing and diffusion combustion proportion in the cylinder is also different, thus affecting the combustion process. The result shows that, with regard to B60L40 and B40L60, cylinder combustion pressure and average temperature are higher, combustion speed is faster, combustion is more sufficient, and combustion process is better. B60L40 has the highest NO generation but the lowest soot generation, and B20L80 has the lowest NO generation but the highest soot generation.
