14. Performance and Emission Test of C.I. Engine Using Biodiesel

The most efficient primary drivers are diesel engines. In order to safeguard the global environment and long-term security of energy, alternative fuels with equivalent qualities to petroleum-based fuels need to be developed. Contrary to the rest of the globe, India’s demand for diesel fuels is around 6 times that of petrol hence it is logical to look for alternatives to mineral diesel. Bio generated fuels present the developing nations with a viable answer to the double crises of depletion and degradation of fossil fuels in the environment. Due to the worldwide emphasis on the reduction of greenhouse gases (GHGs) and a clean development mechanism (CDM), bio-fuels are given additional emphasis. The usage of vegetable oil increases the usage of gasoline and Brake-specific fuel consumption (BSFC). It is injected in droplets to compensate for the insufficient mixing of fuel. CI engine is performed without substantial problems of long-term operation and durability. However, the transesterification step requiring chemical and process heat inputs adds significant processing costs. Vegetable oils can be crucial to decentralised power production for irrigation and electricity in rural and remote parts of developing nations where grid electricity is not accessible. Different types of vegetable oils in these remote places are cultivated/produced locally, however, owing to logistics challenges in rural locations they cannot be processed chemically. Hence, using heated or blended vegetable oils as petroleum fuel substitutes is an attractive proposition. Given this fact, Jatrophan oil on engines, typically used for agriculture and irrigation, and the decentralising generation of electricity, was used for a number of engine experiments in the current research. In order to minimise different operating issues, heating and mixing were utilised to reduce the viscosity of Jatropha oil.
