Performance And Emissions

In today’s world we see that the demand for gasoline and cars keep increasing and one problem which is significantly seen is that we either opt for a fuel which provides higher performance or for a fuel which provides lesser emissions. In this study we aim to provide higher performance and lower emissions by combining two chemicals or octane boosters, namely ethanol and toluene with gasoline and find out its performance and emission characteristics when compared with traditional gasoline and ethanol-gasoline blend. In this study we have made four blends which are PP, E10, E10T5 and E20T5 which are tested against two performance parameters which are Specific Fuel Consumption, Brake Thermal Efficiency with respect to brake power and emissions parameter which are Carbon Dioxide, Carbon Monoxide, Oxides of Nitrogen and Hydrocarbon with respect to brake power as well. In each of these performance and emissions parameters, the blends are compared and we find that E20T5 has the highest performance and E10T5 has the lowest emission.

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.

Overall Performance

Dual fuel diesel (DFD) engines have been gaining popularity due to the flexibility of using both bio and fossil liquid and gaseous fuels. Further, the efficient combustion in DFD mode with bio liquid and gaseous fuel can greatly reduce the greenhouse gas emissions as well as the dependency on fossil diesel. In recent times, a host of investigation has been done in normal dual fuel diesel (nDFD) mode with pure diesel and biogas. However, the engines with ethanol blended with diesel and intake charge (biogas–air mixture) with preheating have not been studied. In the present study, 5% ethanol blended with diesel (E5) and biogas with preheating are used in dual fuel engine (DFD-E5) to find their performance and emission characteristics. In order to have a direct comparison of performances, an engine with pure diesel (E0) and biogas with preheating is also tested in dual fuel mode (DFD-E0). In all the cases, the effect of total equivalence ratio on engine overall performance has also been investigated. In DFD-E5 mode, and at the maximum torque of 21.78 N·m, the brake thermal efficiency (BTE) increases by 2.98% as compared to nDFD mode. At the same torque, there is no trace of carbon monoxide (CO), whereas there is a reduction of hydrocarbon (HC) emission by 62.22% with respect to pure diesel (PD) mode. The nitrogen of oxides (NOx) is found to decrease in DFD modes in contrast to PD mode.

The present work investigates the effect of change in combustion chamber geometry on performance and emission characteristics of single cylinder diesel engine fuelled with mahua biodiesel. Since plant oil derived from the mahua tree has high fatty acids, it undergoes esterification followed by transesterification process to reduce its viscosity. Experiments were conducted using a blend of 20% biodiesel (B20) 40% biodiesel (B40) with diesel and compared with diesel by using two types of combustion chamber geometry, explicitly hemispherical and modified hemispherical combustion chamber. Performance parameters such as Brake Thermal Efficiency (BTE), Brake Specific Fuel Consumption (BSFC) and emission parameters like Unburned Hydro Carbon (UBHC), Oxides of Nitrogen (NOx) were studied from the diesel engine with above mentioned configurations. It is obvious that there is considerable improvement in the performance parameter viz, BTE, BSFC and reduction in UBHC emissions by using the modified geometry piston. However, the NOx emission was found to be higher than that of standard configuration. The results obtained from the blend B20 at modified combustion chamber geometry are on par with diesel and hence mahua biodiesel can be suggested as an alternative fuel for Compression Ignition (C.I) engine with modified combustion chamber geometry.

Diesel engines are widely used for their low fuel consumption and better efficiency. An investigation was carried out with a single cylinder diesel engine to establish the effects of alumina nanoparticle incorporation into the Canola biodiesel (BD) emulsion fuel. The Canola BD was formed from the Canola oil by transesterification process, and later the Canola BD emulsion fuel was prepared in the fraction of 83% of Canola BD, 15% of water, and 2% of surfactants (by volume). The alumina nanoparticles were blended with the Canola BD emulsion fuel at different ratios systematically. The entire study was conducted in the diesel engine using the three fuels, namely, neat BD, Canola BD emulsion fuel, and alumina nanoparticle blended Canola emulsion fuels consecutively. The experimental results revealed a considerable improvement in the brake thermal efficiency (BTE) for the alumina blended Canola emulsion fuels compared with that of neat Canola BD and Canola BD emulsion fuel. At the full load, the BTE observed for the Canola BD fuel was 30.7%, whereas it was 27.81% and 31.6% for the Canola BD emulsion fuel and alumina nanoparticle blended emulsion fuel, respectively. The use of a nanoparticle blended BD fuel reduced the hydrocarbon (HC) and carbon monoxide (CO) emissions but increased oxides of nitrogen (NOx) emissions due to the increased oxygen content in the BD fuel but it was reduced in nanoparticle blended fuel. The smoke emission was reduced by 50% with the use of the nanoparticle blended emulsion fuel.

This paper presents the experimental work to investigate the effect of Re-entrant and Toroidal combustion chambers in a DICI Engine. The two combustion chambers namely Re-entrant combustion chamber (RCC) and Toroidal combustion chamber (TCC) were fitted in a 4.4 kW single cylinder Direct Injection Compression Ignition (DICI) engine and tests were conducted with diesel. The influences of the combustion chamber geometry characteristics on combustion, performance and emissions characteristics have been investigated. This investigation shows the peak pressure of re-entrant chamber is higher than that of toroidal chamber. The heat release rate and brake thermal efficiency for re-entrant chamber are slightly higher than that of toroidal chamber. Specific fuel consumption is lower for toroidal chamber than that of re-entrant chamber. The enhancement in reduction of carbon monoxide, hydrocarbon is observed for Re-entrant chamber compared to the Toroidal chamber. Oxides of nitrogen are reduced for toroidal chamber than that of re-entrant chamber.

Utilization of biodiesel results in lower emissions of hydrocarbons, carbon mono oxide, and smoke. But with the use of biodiesel as fuel emission of Oxides of nitrogen increases along with this some performance parameters also deteriorated. In the present investigation, the fact has been used that, the magnetization of fuels containing hydrocarbon changes the chemical properties as well as orientation and arrangement of molecules of fuel. In this experimental investigation density and calorific values of biodiesel have been determined. In another setup of experimentation on a single-cylinder four-stroke diesel engine, observations are taken with diesel, biodiesel blend containing 20% biodiesel (BD20), and magnetized biodiesel (BD20+MF) as fuel. Results of this investigation show that, the magnetization of biodiesel is not only helpful in increasing performance parameters like brake specific fuel consumption and brake thermal efficiency but also it helps to control the emissions of carbon mono oxide, oxides of nitrogen, hydrocarbons, and smoke. Maintaining the magnetic field just before the entry of the combustion chamber on the fuel line is a little hard, due to the regular increase in temperature of the spot where magnets are kept. It is possible that, if the strength of the magnetic field is increased then, there may be further improvement in performance and engine parameters, as in this investigation only 4000 Gauss Magnetic field has been used.
