1. Rapid development of Chinesemotorcycle industry and emission problem
1.1 Annual output analysis
1.2 Status of Chinese 2-T motorcycle emissions
1.3 Status of Chinese 4-T motorcycle emissions


1.1 Annual output analysis1.1-(a)Annual output and sales volume
Average augmentation of annual output from 1991 to 2000 was 27.6%


1.1-(b) Engine displacement of Chinese motorcycles were being concentrated in 50, 100 and 125 mL1.1-(c) Market share of Chinese 2 stroke motorcycle was being rapidly reduced to 16.17% in 2000

1.1-(d) Output proportion of 2-wheels to 3-wheels Chinese motorcycles was about 20 ~ 26.7:1

1.2Status of Chinese 2-T motorcycle emissions

1.3 Status of Chinese 4-T motorcycle emissions
