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.

In present scenario researchers focusing the alternate sources of petroleum products. Based on this, current research work focused the emission study of its characteristics and potential as a substitute for Diesel fuel in CI engines. Current research biodiesel is produced by base catalyzed transesterification of rice bran oil is known as Rice Bran Oil Methyl Ester (Biofuel). In this research various proportions of Biofuel and Diesel are prepared on volume basis. It is used as fuels in a four stroke single cylinder direct injection Diesel engine to study the performance and emission characteristics of these fuels. Varieties of results obtained, that shows around 50% reduction in smoke, 33% reduction in HC and 38% reduction in CO emissions. In result discussion a different blends of the brake power and BTE are reduced nearly 2 to 3% and 3 to 4% respectively around 5% increase in the SFC. Therefore it is accomplished from the this experimental work that the blends of Biofuel and Diesel fuel can successfully be used in Diesel engines as an alternative fuel without any modification in the engine. It is also environment friendly blended fuel by the various emission standards.

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.

Increased environmental awareness and depletion of fossil petroleum resources are driving industry to develop alternative fuels that are environmentally more acceptable. Transesterified vegetable oil derivatives called ‘biodiesel’ appear to be the most convenient way of utilizing bio-origin vegetable oils as substitute fuels in diesel engines. The methyl esters of vegetable oils do not require significant modification of existing engine hardware. Previous research has shown that biodiesel has comparable performance and lower brake specific fuel consumption than diesel with significant reduction in emissions of CO, hydrocarbons (HC), and smoke but slightly increased NO x emissions. In the present experimental research work, methyl ester of rice-bran oil is derived through transesterification of rice-bran oil using methanol in the presence of sodium hydroxide (NaOH) catalyst. Experimental investigations have been carried out to examine the combustion characteristics in a direct injection transportation diesel engine running with diesel, biodiesel (rice-bran oil methyl ester), and its blends with diesel. Engine tests were performed at different engine loads ranging from no load to rated (100 per cent) load at two different engine speeds (1400 and 1800 r/min). A careful analysis of the cylinder pressure rise, heat release, and other combustion parameters such as the cylinder peak combustion pressure, rate of pressure rise, crank angle at which peak pressure occurs, rate of pressure rise, and mass burning rates was carried out. All test fuels exhibited similar combustion stages as diesel; however, biodiesel blends showed an earlier start of combustion and lower heat release during premixed combustion phase at all engine load-speed combinations. The maximum cylinder pressure reduces as the fraction of biodiesel increases in the blend and, at higher engine loads, the crank angle position of the peak cylinder pressure for biodiesel blends shifted away from the top dead centre in comparison with baseline diesel data. The maximum rate of pressure rise was found to be higher for diesel at higher engine loads; however, combustion duration was higher for biodiesel blends.

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.
