Since so many years all the automobile engines are running by using the fossil fuels. Day by day the usage is increasing. So, by using the fossil fuels it reaching the last stage and finally it leads to the depletion. So, the fossil fuels are the responsible for air pollution, global warming, and the gradually increasing of global climate. So, the algae biofuels are considered to be the most renewable source of energy and also it is eco-friendly. Microalgae considered to be the potential source which can produce biofuel from algae. Nitrates, phosphates, and carbon dioxide which were produced from atmosphere are consider to be growing environment for algae. Spirulina is a blue-green algae. Autotrophic and alkallophyletic are the two attributes of spirulina. For spirulina lesser amount of sunlight is needed than the homes. pH is the important ingredient in the culture medium. After the transesterification process about 87.75% of biodiesel yield was obtained at optimum level conditions. By comparing of both spirulina bio-oil and chlorella bio-oil the parameters like viscosity and density of chlorella were very equally to the conventional diesel fuel. By the above reasons spirulina is strongly considered to be a potential raw material or feedstock for the biodiesel production to be used in diesel engines. For this investigation to measure the engine performance parameters like exhaust temperature, brake specific fuel consumption and emission parameters like hydrocarbons, carbon dioxide, nitrogen oxides, oxygen, carbon monoxides and smoke are measured by changing the injection timings like retard 23 degree, retard 21 degree and retard 19 degree. Finally B20 is the blend taken and this blend is mixed with 75 ppm of Titanium dioxide as a nanoparticle experiment was conducted on four stroke, twin cylinder diesel engineused. |
