Thermodynamic Analysis and Emission Calculation of Diesel Engine Using Ethanol Diesel-oil Alternative Fuel

The thermal balance analysis and exergic analysis of the diesel engine for the 30 m class patrol boats are performed to investigate the loss distribution of heat and exergy for every part of the diesel engine. For the ethanol diesel-oil alternative fuel,the thermal balance and exergic analysis of the diesel engine are carried out also. The results illustrate that,after using ethanol diesel alternative fuel,at the same time keeping fuel exergic and useful work as a constant,the fuel consumption increased 3. 456%. However,thermal efficiency slightly increases and the carbon dioxide of diesel engine emission is greatly reduced
