With the number of automobible used growing up every year, vehicle exhaust gas hasbecome the major origin of bigger cities' air po1lution. Laws and regulation are rather unstrict. Completely control of the pollutions has not jet begun. Rules and regulations, which could beoperated practically, must be perfected and revised step by step closing to international advancedstandards.
