Experimental Investication of DI Diesel Engine Using Biodiesel Blends With Different Injection Pressures
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 11
Abstract
The increasing industrialization and modernization of the world has led to a steep rise for the demand of petroleum products. Therefore, countries not having these resources are facing a foreign exchange crisis, mainly due to the import of crude oil. Hence it is necessary to look for alternative fuels, which can be produced from materials available within the country. Non-edible vegetable oils such as Pongamia, Jatropha, Madhuca Indica, etc can either be fully or partially substituted with diesel oil. The high viscosity of vegetable oils can be reduced by using transesterification process. The concept of trans-esterification process of non-edible oil with an alcohol provides a clean burning fuel (Commonly known as Biodiesel) having less viscosity. The result of this investigation shows that the neat biodiesel from Madhuca Longifolia oil gives slightly higher efficiency than diesel fuel. The biodiesel substantially reduces unburned hydrocarbons, carbon monoxide and particulate matter in exhaust gases, and slightly higher NO than diesel fuel but it is found that there is no significant difference between diesel and biodiesel in regard of NO and exhaust gas temperature.
