The project for this year will continue to assist the EPA
(Environmental Protection Agency) with the management of motorcycle
exhaust pollution, including the certification of new vehicle model, the
audition of new vehicle, examination on emission control components,
etc.. The project will also continue to assist the EPA to modify the
unsuitable regulations relative to the “Issue and Annulment of the
Certificate for Qualification for Examination and Inspection of Exhausts
of Motorcycles.” if necessary. In addition, the project will implement the
recall investigative tests for the in-used motorcycles.
Until now, the project had issued 191 certificates, including 700
vehicle models. The project also had completed audits for 96 motorcycles,
and all had passed the test. The project also had examined 9 motorcycles
for their emission control components, and all had passed the test. The
manufacturers had applied for 31 pieces of endurance tests this year. For
the emission quality control in production line, we found that some
engine families’ CO had higher emissions and variation, but the HC+NOx
didn’t. For the green motorcycle ranking, the Techno GT 125 for
KYMCO was the best. For the survey of mutual recognition of
motorcycle emission certificate, it needs the Taiwan Government to
negotiate with other countries.
The electronic certification management and data exchange system
had been laid out this year and we also had completed the first version
application system.
For the 6th stage emission regulation, WMTC should be merged into
the proceeding regulation. In the deterioration factors study, we found
the deterioration factor may be higher for greater than 150cc and lower
for less than 50cc, the deterioration factor for injection system is lower
than the carburetor system. The project had surveyed the EU and the
Japan 2007 model year motorcycle certification data, the analysis showed most of the EU certification data can’t pass our emission regulations
respectively, and all the Japan certification data can’t pass our emission
regulations. In this project, we studied the correlation between emission
and idle speed, the emissions comparison among driving patterns. Test
results showed the idle emission may increase with increasing speed, the
CO emission in Stage 4 were higher than that in WMTC and Stage 5, the
HC and NOx emission in WMTC and Stage 5 showed good correlation. In
the maintenance factor study, the CO and HC emissions could reduce by
way of maintenance, but the NOx didn’t. We also found the CO and NOx
emissions may rise for the vehicle speed over 40 km/h. For the
motorcycle exhaust emission estimation, we had estimated our domestic
motorcycle exhaust CO, HC, NOx and CO2 emission are 219,747,
120,326, 12,301, and 3,405 tons per year.
For the in-use motorcycle investigation tests, all the 10 engine
families had passed the tests.
