“…As new emission regulations of diesel engines are increasingly stringent, the necessity of clean combustion increases accordingly, and proper deployment of fuel spray, cylinder air flow and combustion chamber shape can achieve internal purification, control engine emission from its source, lighten the workload of after-treatment, and adjust the balance of NOx emission and soot emission to achieve a trade-off between NOx and soot emission, or adapt to the actual requirement of after-treatment equipment. To achieve engine internal purification, researches in past decades have done abundant work in combustion chamber shape modification [2], fuel physical and chemical character modification [3], and fuel supply system parameters modification [4]. To optimize fuel supply system, important parameters include injection timing [5], UMH injection nozzle [6], spray characteristics [7], etc.…”

Abstract. This paper simulated a six-cylinder diesel engine with 3d model, and optimized combustion and emission through modify project distance of injector and nozzle angle. Simulation result shows that appropriate project distance will enhance entraining power of vortices and reduce soot generation without increasing NOx generation; yet inappropriate nozzle angle will deteriorate combustion in either clearance volume or combustion chamber bowl. Variation in either project distance or nozzle angle has greater influence on soot generation than NOx generation, and both can be optimized to reduce soot emission without affect NOx emission significantly.

“…This means that the oil mixes with air and causes combustion efficiency to suffer. Thus the engines run on peanut oil record low performance [3][4][5]. Apart from that, a particular day engine test had done on peanut oil shows several other side-effects as deposit formation, carbon build up and lubricating oil contamination.…”

Compression ignition engines are ubiquitous and quite popular in the automobile industry today. Many vehicles used today run on compression ignition engines. Considering the significant market presence of CI engines, this experiment aims to looks to investigate and possibly improve the effect a certain fuel blend has on CI engine parameters. In particular, the endeavor of this project is to study the effect on various loading conditions of a CI engine running on palm oil blended (D90A10, D60A40, D80A20, D70A30, D50A50, D40A60) with conventional diesel. The comparative measurements of CO2 and NOX have been stated and analyzed, along with BSFC and brake power. The results showed that blend of biodiesel D90A10 showed average increase in brake power than diesel.

“…This is because other renewable energy sources such solar, wind, etc, has so far proved to be able to provide only a small fraction of the world energy, mainly in the developed world and with high cost (Dinica [2], Krozer [3]). Biofuels not only have the potential to replace conventional fuels, but also produce less emission of harmful gases compared to conventional fuels when burned under specific controlled environment such as Internal combustion Engines -ICEs (Enweremadu and Rutto [4], or other types of burners (Jaichandar and Annamalai [5]. However, for an optimal use by the existing combustion infrastructure (combustion chambers in ICEs or other burners), an effective combustion process is essential to ensure the maximum energy is extracted from Biofuels with a minimum impact on air quality.…”

Numerical studies based on steady Computational Fluid Dynamics (CFD) for reactive flows were performed with the objective of validating advanced reaction mechanisms used to study spray combustion for both conventional and Biofuels. The SST-4 equation model was used to model turbulence, while more than one (comprehensive) reaction mechanisms were used to model the combustion of methanol, diesel and biodiesel using CHEMKIN-CFD and Fluent CFD code. Some of the reaction mechanisms used in modelling the current reactive flow simulation was already tested while others were developed during the course of this work. The computational results have shown good agreement with the available experimental data of Widmann and Presser (Combustion and Flame, 129, 47-86, 2002) with the developed reaction mechanism slightly over predicting the temperature range. The CFD results have also shown that most of the harmful emission of the combustion of liquid fuels is less for Biodiesel compared to conventional diesel with the exception of CO 2 . This is in line with the finding of many experimental data.
