Evaporation characteristics influence on exhaust emissions of waste plastic oil petro diesel blends.

The present research is aimed to investigate the influence of evaporation and puffing characteristics on the exhaust gas emissions of waste plastic oil and desired blends with petro diesel. Different volumetric proportions of plastic oil blends such as P20, P40, P60 and P80 are prepared and their thermo-physical properties were measured. The evaporation rates of prepared blends were evaluated in a convective environment and compared with the non-blended plastic oil, traditional petrol diesel. These were supplied to a test engine for evaluation of combustion and emission characteristics. The results are shown that the puffing is formed specifically at 773K to 873K at fluctuation evaporation phase in the prepared blends whereas P20 and P80 possess similar specific fuel consumption with huge variation in CO formation at exhaust emissions. The increase in temperature is reduced the time for the formation of bubble and puffing at higher volume blends but the phenomena of incomplete combustion increased the emissions rate.
