Performance, Emission and Combustion Characteristics of a Diesel Engine using “Cotton Seed Oil and Microalgae Oil” Methyl Ester
Performance, Emission and Combustion Characteristics of a Diesel Engine using “Cotton Seed Oil and Microalgae Oil” Methyl Ester.
Abstract: The need of energy is increasing continuously, because of increase in industrialization as well as human population. The basic sources of this energy are petroleum, natural gas, coal, hydro and nuclear. The major disadvantage of using petroleum based fuel is atmospheric pollution. Petroleum diesel combustion is a major source of greenhouse gases (GHG). Apart from these emissions, petroleum diesel combustion is also major source of other air contaminants including NOx, SOx, CO, particulate matter and volatile organic compounds, which are adversely affecting the environment and causing air pollution. These environmental problems can be eliminated by replacing the petroleum diesel fuel with an efficient renewable and sustainable bio fuel. Biodiesel derived from various sources like crops cannot be satisfy the fraction of the existing demand for transport fuels. Microalgae appear to be the source of renewable biofuel that is capable of meeting the global demand for transport fuel. Microalgae is a sunlight driven oil production species. It produces more oil content than the oil crops and it is abundantly available in the seas. As the earlier work of cotton seed oil (2nd generation) shows the increased emission of NOx and BP and BTE. Microalgae have an ability to reduce the NOx discussed in the earlier work. In this work, the scope is to reduce the harmful gases exhausted from emissions of IC engine. To reduce the harmful emissions from 2nd generation bio fuels with maintaining same BP and BTE, the blends of Cotton seed oil ester (2nd generation) and Microalgae oil ester (3rd generation) at various proportions are used.
