Report Errors
In this study, pilot experiments were conducted by setting operation conditions to analyze characteristics of emission for air pollutant from small two-stroke engines. Emission factors of the measured concentration of pollutant were compared with EEA. Emission factor of CO analyzed by experiments - concentration, flow rate, fuel consumption, etc. - was estimated at 816,011 g-CO/ton-fuel in average. It was confirmed that more than 80% of the fuel consumption is discharged to the Carbon Monoxide, and that as the engine load becomes higher, emission factor of CO increases in the form of log function. The average emission factor of NO<SUB>x</SUB> and PM<SUB>10</SUB> was 3,801 g-NO<SUB>x</SUB>/ton-fuel and 3,730 g-PM<SUB>10</SUB>/ton-fuel each. The deviation was not large by comparing the fuel-based emission factor of EEA and the result of this study. Since considerable pollutants are expected to be discharged from the small twostroke engines, continuous research and support of the policy is required.
