Performance And Emission

This paper presents a comparative analysis of the diesel engine performance and emission characteristics, when operating on diesel fuel and various diesel-biodiesel (B10, B20, B40, B60) blends, at various loads and engine speeds. The experimental tests were performed on a four-stroke, four-cylinder, direct injection, naturally aspirated, 60 kW diesel engine D-243. The in-cylinder pressure data was analysed to determine the ignition delay, the Heat Release Rate (HRR), maximum in-cylinder pressure and maximum pressure gradients. The influence of diesel-biodiesel blends on the Brake Specific Fuel Consumption (bsfc) and exhaust emissions was also investigated. The bench test results showed that when the engine running on blends B60 at full engine load and rated speed, the autoignition delay was 13.5% longer, in comparison with mineral diesel. Maximum cylinder pressure decreased about 1–2% when the amount of Rapeseed Methyl Ester (RME) expanded in the diesel fuel when operating at full load and 1400 min–1 speed. At rated mode, the minimum bsfc increased, when operating on biofuel blends compared to mineral diesel. The maximum brake thermal efficiency sustained at the levels from 0.3% to 6.5% lower in comparison with mineral diesel operating at full (100%) load. When the engine was running at maximum torque mode using diesel – RME fuel blends B10, B20, B40 and B60 the total emissions of nitrogen oxides decreased. At full and moderate load, the emission of carbon monoxide significantly raised as the amount of RME in fuel increased.

Diesel Emissions

This research work investigates diesel combustion and exhaust emissions with additives addition to conventional diesel fuel in a four-stroke naturally aspirated direct injection (DI) diesel engine. The additives include DGM, and liquid cerium. The results show that with the addition of DGM to diesel fuel, brake specific energy consumption (BSEC) and all diesel emissions are significantly reduced. The volumetric blending ratios of additives to diesel fuel are 0, 25, 50, 75 and 100%. All emissions including smoke emissions decrease with the increase in oxygen content in the fuel and it is noted that smoke emission completely disappeared at an oxygen content of 36 wt–%. The reason for improvement in BSEC with the addition of additives to base diesel fuel is the improvement of degree of constant volume combustion, and the reduction of the cooling loss. Engine noise and odor concentrations are remarkably reduced with diesel-additive blends. Significant improvement in BSEC and exhaust emissions is not only found at medium load condition but also at high load condition. Key words: Diesel engine, DGM, emissions, BSEC, and cooling loss

The present work deals with the experimental investigations on the effect of refined rice bran oil and its blends with diesel on performance and emission characteristics of diesel engine with different combustion chamber geometry. The engine was tested with various neat vegetable oils and it was found that with refined rice bran oil the performance and emission characteristics were comparable with that of neat diesel. The K- factor of the combustion chamber geometry (ratio of the piston bowl volume to the clearance volume) was maintained at 0.74. The D/d ratio (ratio of piston crown diameter to piston bowl diameter) was altered to achieve re-entrant and torroidal shapes from spherical shape. Tests were carried out for each blend, with particular geometry of combustion chamber. Results with different combustion chamber geometry and different blends have been compared.

Different Characteristics

In recent trends due to the increase in rate of petrol and diesel prices biodiesel has been used as an alternate fuel in many of the fast developing countries. However in our country also many research work has been done using different oils. In this paper instead of using a single oil, two different oils was mixed with diesel in different blends and the emissions were calculated and the results were plotted. The two different oils used was the Cashew nutshell liquid (CNSL) and the Rice bran oil. Cashew oil is found to be a by-product which is available from the Cashew industry and after the transesterification process the cardanol obtained was used without any modifications. Rice bran oil is mostly found in the places where rice is grown in a huge quantity and more number of research works has not been done in this oil. By the transesterification process the rice bran oil was prepared and mixed with the CNSL in the different proportions, which was also mixed with diesel in some amounts and the different characteristics were evaluated and plotted.

Biodiesel, a derivative of vegetable oils and animal fats, is used nowadays as an alternative renewable and sustainable fossil fuel. In this work, the investigation of manufacture, characterization, and results of biodiesel blends are carried out using two important feedstock’s, sunflower oil and ricebran oil on engines. For the collective advantageous of sunflower oil and ricebran oil, the two biodiesels are combined together and the mixture is analysed to assess the engine performance and emission characteristics. NaOH catalyzed transesterification process is used for producing the Biodiesels A 4.4 kW, four-stroke, single-cylinder and direct fuel injection diesel engine is used for measuring physic-chemical with full load and varying speed conditions and using the specifications of ASTM D6751 standard, the properties are compared. It is observed that the Biodiesel mixtures produce a low brake torque and high brake-specific fuel consumption (BSFC) in addition to the reduction of CO and HC emissions. NOx, however, is reduced considerably with the improvement of brake thermal efficiency. The Performance analysis indicates that the mixture of sunflower oil and ricebran oil improves performance and emission characterizes over sunflower oil and ricebran oil biodiesel when they are unmixed..

Biodiesel is an alternative fuel for diesel engines which doesn?t contain pollutants and sulfur; on the contrary it contains oxygen. In addition, both physical and chemical properties of sunflower oil methyl ester (SME) are identical to diesel fuel. Conversely, diesel and biodiesel fuels are widely used with some additives to reduce viscosity, increase the amount of cetane, and improve combustion efficiency. This study uses diesel fuel, SME and its mixture with aviation fuel JetA-1 which are widely used in the aviation industry. . Fuel mixtures were used in 1-cylinder, 4-stroke diesel engine under full load and variable engine speeds. In this experiment, engine performance and emission level are investigated. As a conclusion, as the JetA-1 ratio increases in the mixture, lower nitrogen oxide (NOx) emission is measured. Also, specific fuel consumption is lowered.

Moringa Oil

World at present is confronted with the twin crisis of fossil fuel depletion and environmental pollution. Rapid escalation in prices and hydrocarbon resources depletion has led us to look for alternative fuels, which can satisfy ever increasing demands of energy as well as protect the environment from noxious pollutants. In this direction an attempt has been made to study a biodiesel, namely Moringa Oil Methyl Esters [MOME]. All the experiments were carried out on a 4.4 kW naturally aspirated stationary direct injection diesel engine coupled with a dynamometer to determine the engine performance and emission analysis for MOME. It was observed that there was a reduction in HC, CO and PM emissions along with a substantial increase in NOx. MOME and its blends had slightly lower thermal efficiency than diesel oil.
