Exhaust Emission from Motorcycles and Technical Pollution-Reducted Measures

Motorcycles are making pollution because of their 2 stroke engine. This paper analyses character of ollution standards of motorcycles in our country compared with foreign standards. The paper also inquirs into methods about reducing motorcycles pollution. An advanced purificatory silencer using catalysis technique is a good device by which new or old motorcycles can conform to pollution standards.
