Due to depletion of fossil fuels, concerns about energy security and global warming make renewable energy resources more attractive. In this regard, using biodiesel seems to be a possible and feasible source of energy for transportation. This paper presents an investigation of the performance and emission characteristics of CI engine using 10% blend of rice bran oil as fuel and ceramic oxide coated piston.

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.

Increasing Demand

Increasing demand and rapid depletion of fossil fuels have together prompted the researchers of many countries to look for alternate renewable fuels. This study is an attempt to test the feasibility of rice bran oil as fuel in C. I. engine in its original and in its refined form. It is generally produced from rice bran which is a by-product produced during paddy processing. Its viscosity though relatively higher than diesel can be reduced by natural sedimentation process. In this attempt, the performance and emission characteristics of rice bran oil and its refined form were studied and compared with diesel by employing them as a fuel in a single cylinder, direct injection, 4.4 KW, air cooled diesel engine. The performance characteristics revealed that the brake thermal efficiency of the rice bran oil was higher than its refined form and were marginally lower than that of diesel. Emission measurements were carried out using MRU Delta 1600L gas analyzer and the soot concentration was measured with AVL smoke meter. It was found that though blends of rice bran oil with ethanolexhibited greater soot concentration characteristics than rice bran oil and diesel at all loads, it exhibited desirable characteristics for other emissions such as lower CO, HC, NOx emissions and lower exhaust gas temperatures with increasing load.

Abstract Energy security is a matter of particular importance to all the world's states, whether they are producers or consumers of energy resources. For a long time, fossil energy resources have been the only source of energy used on a planetary scale. When mankind realized that fossil energy resources are a finite source of energy and that their intensive use causes many environmental problems, the most important of which is related to global warming, they have tried to find alternative sources of energy. Thus, concerns have arisen about the use of renewable energy on a wider scale, with both individual concerns of states that have potential in this area and collective concerns, such as at EU level, which has proposed by 2020, the share of energy from renewable sources used by the Union states is at least 20% of total consumption. Renewable energy resources may be an alternative to fossil fuels, but at the same time it has a number of limitations and vulnerabilities. Ensuring energy security means a comprehensive approach, understanding of limitations and reducing vulnerabilities

Over the past several years, there has been increased interest in alternative diesel fuels to control emissions and provide energy security. Biodiesel is a fuel that can be made from renewable biological sources such as vegetable oils and animal fats, has been recognized as an environment friendly alternative to mineral diesel. In present investigation, rice bran oil (non-edible) was transesterified to methyl ester and reaction conditions for transesterifcation process for rice bran oil were optimized. Various properties like viscosity, density, flash point, calorific value of the biodiesel thus prepared are characterized as per ASTM norms (ASTM D6751) and found comparable to diesel. Steady state engine dynamometer test at full throttle conditions have been carried out to evaluate the performance and emission characteristics of a medium duty transportation DI diesel engine. Engine was fuelled with various blends of rice-bran oil biodiesel (ROME) and mineral diesel ranging from 5% biodiesel to 100% biodiesel (5, 10, 20, 30, 50, and 100%). Performance and emission data were compared to the baseline data obtained using mineral diesel. Same engine without any hardware modification has been adopted for tests on all fuel blends. The results of this experimental investigation showed that biodiesel and biodiesel blends exhibited almost similar torque and power characteristics. Biodiesel blends up to 20% produced slightly higher torque and improved performance. Improvement in fuel conversion efficiency was found for lower concentration blends i.e. up to 20%. Lowest efficiency was found for 100% biodiesel blend. All the biodiesel blends emitted lower total hydrocarbon, carbon monoxide emissions and smoke opacity but slightly higher NOx emissions during the full throttle tests. Emission tests with all the fuel blends have also been carried out using European 13 MODE test (ECE R49) procedure. Drastic reduction in THC and CO and slight increase in NOx was observed.

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.

Alternate Source

This research is aimed at finding a sustainable alternate source of energy that can be used as a substitute for conventional fuel sources, which are fast dwindling towards the point of exhaustion. Bio-diesels are viewed as an effective alternate source of energy which can be better than conventional fossil fuels in its performance, combustion and greenhouse gas emission rates. The oil of rice bran methyl ester is used for experimentation. The oil is blended in different ratios with pure diesel in a process known as blending. The various blends are then subjected to performance test in a diesel engine. The biodiesel blends have also been tested for emission properties with and without exhaust gas recirculation. The results reveal that rice bran biodiesel emits less amount of carbon monoxide emissions.
