In this experimental investigation compacts the performance and emissions of compression ignition engines fuelled with MgO nano additive, maducaindica bio diesel blends were examined. Based upon the previous literatures only 20% mahuca methyl ester fuel blends without nano additives is suitable for compression ignition engine without affecting engine efficiency and its characteristics. In this paper magnesium oxide nano additives are added into the 40% Mahucaindica biodiesel- diesel blends at the rate of 50ppm for developing the test fuels. In this nano additives improve the properties of diesel fuel like viscosity, calorific value and decreased the flash point and fire point. Then compared the performance and emissions differences of all blended fuels used as a fuel in a diesel engine. The observation of results, 40MgO + 50ppm blended fuels brake thermal efficiency is improved then CO, HC, CO2and smoke decreased compared to other fuel blends. The results are taken into account, a blend of 40MgO+ Mgo50ppm is the best blend ratio compared than other blends with nano additives.

Combustion Phase

The performance and emissions of a compression ignition engine fuelled with diesel/dimethoxymethane (DMM) blends were studied. The results showed that the engine's thermal efficiency increased and the diesel equivalent brake specific fuel consumption (b.s.f.c.) decreased as the oxygen mass fraction (or DMM mass fraction) of the diesel/DMM blends increased. This change in the diesel/DMM blends was caused by an increased fraction of the premixed combustion phase, an oxygen enrichment, and an improvement in the diffusive combustion phase. A remarkable reduction in the exhaust CO and smoke can be achieved when operating on the diesel/DMM blend. Flat NO x/smoke and thermal efficiency/smoke curves are presented when operating on the diesel/DMM fuel blends, and a simultaneous reduction in both NO x and smoke can be realized at large DMM addition. Thermal efficiency and NO x give the highest value at 2 per cent oxygen mass fraction (or 5 per cent DMM volume fraction) for the combustion of diesel/DMM blends.

Nano Additives

The present study examines the effect of silicon dioxide (SiO2) nano-additives on the performance and emission characteristics of a diesel engine fuelled with soybean biodiesel. Soybean biofuel was prepared using the transesterification process. The morphology of nano-additives was studied using scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS). The Ultrasonication process was used for the homogeneous blending of nano-additives with biodiesel, while surfactant was used for the stabilisation of nano-additives. The physicochemical properties of pure and blended fuel samples were measured as per ASTM standards. The performance and emissions characteristics of different fuel samples were measured at different loading conditions. It was found that the brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) increased by 3.48–6.39% and 5.81–9.88%, respectively, with the addition of SiO2 nano-additives. The carbon monoxide (CO), hydrocarbon (HC) and smoke emissions for nano-additive added blends were decreased by 1.9–17.5%, 20.56–27.5% and 10.16–23.54% compared to SBME25 fuel blends.

Alcohols begin to show a real interest for their use as fuel at compression ignition engines due to require reducing the pollutants emissions, especially NOx emission. Among the primary alcohols, butyl alcohol (butanol) is considered to be of great perspective in its use as fuel in diesel engines due to its properties close to those of diesel fuel. It is miscible with the diesel fuel and the achieved blend is stable. In paper are presented some aspects regarding the diesel engine’s fuelling with butanol and diesel fuel blends using the experimental research and numerical modelling. The use of the butanol as a fuel for diesel engine has led to the reducing NOx emissions with about 25% and the Brake Specific Energetic Consumption (BSEC) with about 5% at the full load and the maximum torque engine speed.

The paper highlights the results of an experimental investigation carried out on Karanja oil as a supplementary for diesel fuel in Compression Ignition engine. In the present study, triglycerides of Karanja oil is converted into mono-ester (biodiesel) using based catalyst transesterfication process. Karanja biodiesel is blended with petroleum diesel in the volumetric proportions of 2−10%. Results reveal that the performance characteristics of Karanja biodiesel blends are well comparable with diesel fuel. The emission characteristics such as CO, HC and smoke are found to be lower for Karanja biodiesel blends at all the engine load conditions compared to diesel fuel. Hence, it is concluded that Karanja oil at lower blends can be used in diesel engine without any substantial engine modification.
