Performance and Emission Evaluation of a Compression Ignition Engine Using Agitated Diesel Fuel

Article Preview

Abstract:

Enhancing the efficiency of normal diesel cycle and gasoline cycle is gaining more importance because of depleting fossil fuel resources and other environmental issues. In normal operation the efficiency of diesel cycle is about 37 - 44%. So diesel cycle efficiency should be increased or otherwise it should be replaced with alternate fuels. Increasing the efficiency of the cycle leads to lower fuel consumption and other economic benefits. Thermal efficiency of the diesel mainly depends on compression ratio and combustion parameters such as injection timing, injection pressure and ignition delay period. Thermal efficiency also depends on fuel properties such as viscosity, density and cetane number (CN). This paper discuss about the performance evaluation of diesel fuel in a CI engine when the fuel properties are pre-enhanced by crystal agitation. In this experiment different size (Micro and Nano) SiO2 crystals are used with commercial diesel fuel in the storage tank and the performance and emission test are conducted. Results of these samples are compared with neat diesel fuel performance.
