The Status of Chinese Motorcycle Emissions and a Study of Application of Catalytic Converter on Two–Stroke Scooter 1999-01-3284

The motorcycle Industry is one of the advantageous industries with developing potentialities in China.

Depending on chassis dynamometer test results from more than 100 motorcycles a motorcycle emission data–base was set up. By using this motorcycle emission data–base the status overview of Chinese motorcycle emissions is given.

Unleaded gasoline will be used throughout china in 2000, which creates essential prerequisite for application of catalytic converter technique.

Catalytic control of motorcycle emissions requires that the catalytic converter must be carefully integrated into the exhaust system. Optimal matching between catalytic converter position and engine performance was achieved through engine tests.

Evaluation of catalytic converters was made through chassis dynamometer tests.

Emission results from motorcycle with the optimum catalytic converter can meet the present Europe motorcycle limitations (The so called motorcycle EURO–1 were taken into force in June 17th 1999[1])
