Abstract
Recently, the air pollution caused by exhaust gas from automobiles is getting worse. Especially, it is very serious along arterial roads and at intersections with heavy traffic. Therefore, so far many researches have been carried out on purifying facilities. This time we have researched on absorptive property of SPM, CO, CO_2 and C_3H_8 and the power efficiency of this system. As a result, we found 1) the removal efficiency of SPM falls as the gas flow ratio and concentration increase. 2) CO and C_3H_8 are scarcely removed regardless of experimental conditions. 3) by changing pressure of the pump, power efficiency of our system is improved. However, it turned out that this system is not good enough as a SPM removal system under the present condition of pollution.
