In this study, the outcome of adding n-butyl alcohol to jatropha methyl ester on the emissions characteristics of compression ignition engines is investigated. Single cylinder diesel engine was fuelled with n-butyl alcohol / jatropha methyl ester blends. The doping volume of n-butyl alcohol to jatropha methyl ester blends was in the range of 10, 20 and 30%. Emission parameters such as Hydro carbon (HC), Carbon monoxide (CO), Nitrogen oxides (NOX) and Smoke emissions were examined at different load conditions. The engine speed was maintained constant throughout the trail. This work resulted in a significant reduction in reduction in all the emissions. Addition of n-butyl alcohol as additive improves the rate of combustion, mixing and vaporization of the blends with air and reduces the emissions associated with it. Further, it can be used in the existing engine with any modification. This also results that the addition of n-butyl alcohol to jatropha methyl ester reduces the emissions associated with it. Further, no damage to engine components was observed during the trail.

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.

Total Elimination

Biodiesel is a promising fuel which shows potential and gradually received attention as a best alternate feedstock for diesel engine. Previous investigations have shown that use of double biofuels in a diesel engine can be a promising aspect for complete elimination of diesel from compression ignition engines which will decrease our dependency on fossil fuels. The tribological performance of injection system is primarily based on the lubricity characteristics of the fuel. So, it is imperative to a more diversified research about the impact of using double biofuels in engine. In the present investigation, different biodiesel-oil blends were investigated using the ASTM D6079 by the reciprocatory friction monitor. The effect of temperature variation on lubricity characteristics was also studied. The biodiesel-oil blends shows improvement in results as compared to diesel. Biodiesel is prone to oxidation due to availability of unsaturation in their moieties. The effects of oxidation on lubricity characteristics were also studied. It was also found that the operating conditions collectively affected the lubricity characteristics of tested feedstocks.

The paper presents an analysis of the constructions of oil pumps for an aircraft compression ignition engine. It is a two-stroke liquid-cooled engine with a power of 100 kW. The system has 3 cylinders and 6 opposed pistons. The paper estimates the required oil pump capacity to make the engine components well-lubricated. Next, automotive oil pumps for diesel engines are analyzed to select a correct pump for aircraft diesel engine applications. Three pump constructions of different constructions and dimensions of a rotor were selected. A measurement bench was designed and built to test these oil pumps in the range of pump shaft speeds from 0 to 4500 rpm and volumetric flow rate up to 150 l/min. The bench also enables stabilization of oil temperature at the required level within the range from 30 to 120oC. In addition, flow resistance through engine slide bearings was simulated by changing the position of a throttling valve at the pump output to regulate pressure in the range of 0–700 kPa. The obtained capacity characteristics of individual pumps versus on oil pressure and temperature allowed us to find an appropriate oil pump to make individual engine nodes well-lubricated.

Pongamia Methyl Ester

This experimental study focuses on investigation of performance and utterance attributes of a normal diesel engine with biodiesel prepared from pongamia. This study aims to reduce the emission of nitrogen oxide by adding an oxidation inhibitor Tert-Butylhydroquinone (TBHQ). The analysis for each sample is to be carried out in compression ignition engine (standard diesel engine). The engine is tested with standard diesel, pongamia methyl ester biodiesel without any additives. Then the analysis is to be carried by adding nano additive copper oxide for about 50 ppm in the above mentioned fuels. From this the best combination is found out and test is again carried out by adding the oxidation inhibitor.

The present research investigated multi-zone single-cylinder four-stroke direct-injection model. The model simulates closed cycle processes and describes the combustion behavior by employing thermodynamic equations of a penetration spray theories. The model has been coded on the base of the programming tools of Matlab software. In this simulation model, the combustion events is divided into five zones, in order to determine the amount of fuel, access air, and amount of products in each zone. The simulation model, produced in this work, provides a more accurate framework for zero dimensional model by introducing physical zones within the model that correspond to the combustion structures in the engine. Comparison the results of the simulation model with other methods in the published researches shows that the behavior of engine parameters with theoretical and experimental earlier works has a good agreement. From the simulation model results can be concluded that, there is a change in the limits of the combustion zones with changing engine speed, amount of injected fuel, intake air pressure, and temperature, especially in the rich premixed burn zone.
