INTRODUCTION
Diesel engine is a very popular prime mover used for surface transportation, agricultural machinery needs and in industries. Diesel engines of more than 6.5 million units are being used only in the Indian agricultural sectors for different activities and the import of petroleum products is a major draw off on our foreign exchange sectors and with increasing demand in future years the condition is likely to become worse.
Hence, it is an urgent need for a country like India to search for an option to run CI engine using a different fuel than the conventional and petroleum based diesel and recently biodiesel, as CI engine fuel alternative, has received more attention among many other possible options. Biodiesel has also…show more content… There is a reduction in all major measures of air pollution except NOx. Biodiesel is biodegradable under environmental conditions when spilled, as it is 100% organic product.
1.8.3 Economic Benefits of Biodiesel The biodiesel can be extracted from any material that contains fatty acids. The various vegetable fats and oils, animal fats, waste greases and edible oil processing wastes can be used as feedstock for the production of biodiesel. The future needs for imported oil to manufacture regular diesel fuel could be reduced by the significant use of biodiesel. The cost of biodiesel is most likely to remain stable than fossil fuel costs in future, as fossil fuel supplies decreases over time. As biodiesel is produced from agricultural feed stocks, it helps in improving economy in rural areas. Some minor changes are needed in refuelling structures and spare parts inventories. It is the only alternative fuel that runs in any conventional unmodified diesel engine. Based on mutagenicity tests, 90% reduction in cancer risks are possible using biodiesel. Major engine problems can be attended by the diesel skilled mechanics
mentioned above require some amounts of energy to achieve fast responses. Additionally, implementation is expensive. Control of an HCCI engine using variable compression ratio strategies has been shown effective.
