    Abstract: Based on the present situation of exhaust emissions from two stroke motorcycle inChina, the common methods about control of the exhaust emissions and the structure and operation principle of catalytic converter have been analyzed. The experiments have been done to study the installation position of the catalytic converter and feeding valve for secondary air ,and influencing factors of the purification rate of the catalytic converter have been analyzed.The experimental results have shown that exhaust emissions from two stroke motorcycle with the catalytic converter and feeding valve for secondary air have been reduced obviously .
