There were four main tasks in the project, first was the management of motorcycle exhaust pollution, the second was the development of the electronic emission certification management system, the third was recall investigative tests for the in-used motorcycles, and the last was the the relative research activities in the field of motorcycle emission control. The achievements were as follows:
(1)The project issued 143 certificates, some engine families’ emissions closed to standards and should be further audited in the future.
(2)The project audited 64 motorcycles; 3 engine families failed in the auditorial test and the manufacturers are carrying out the recall program, so the imported motorcycle’s emissions were not good in the production line and should be further audited in the future.
(3)The project also had examined 46 motorcycles for their emission-control components, and 2 motorcycles failed in the examination, and must correct their certificates.
(4)The manufacturers applied for 16 durability test plans in total, and quitted 2 plans for some reasons.
(5)For production line QC examination, some defects were found such as faults in the QC plans, draws in the QC data analysis, mistakes in QC data, and no licenses in idle test for laboratories.
(6)For the production line emission analysis, we found some engine families had higher emissions and variation in CO and NOx. Those engine families that had had higher emissions and variation should be further audited in the future.
(7)For the year 2009, the estimated motorcycle exhaust emissions for CO, HC, NOx, the evaporative emission and CO2 were 106,068 tons, 79,494 tons, 8,641 tons, 5631 tons and 4,019 kilo-tons respectively.
(8)For the emissions reduction effect, the CO, HC, and NOx reduced 11,870, 4,881, abd 727 tons respectively for the reasons of carrying out 5th stage emission standards and retiring old 2-stroke motorcycles.
(9)For the green motorcycle ranking, 3engine families were chosen for the best of 2010 model year.
(10)The green motorcycle inquiry website had been constructed and was located at: http://car.itri.org.tw/GreenCar/.
(11)The no-paper electronic certification management system had been maped out and the electronic production/sale and QC system also had been constructed.
(12)For the in-use motorcycle emission investigation tests, all the 10 engine families, including 50 motorcycles, had passed the tests.
(13)For the 2009 EU motorcycle emission certificated data analysis, 60% of the transferred data could meet our emission standards. For the 2009 Japan motorcycle emission certificated data analysis, all the transferred data couldn’t meet our emission standards.
(14)For the evaporation emission test, the diural emission wagreater than the hot-soak emission for most of the motorcycles. The SHED emission was greater than the Trap emission.
(15)For the deterioration factor (DF) analysis, our DF were focus among 1~1.3 but the US’s DF were focus among 1~1.2, DF=1 occupied the maximum portion of the deterioration factor, and DF>1.5 also occupied more than 15% of the deterioration factor. If the deterioration factor was calculated by DF3 manner, the emission will be over estimated. The DF showed no difference for different brands. The motorcycles with capacity smaller than 50c.c. may have small DF. The DF for injection system was smaller than that for carburetor system in NOx. The DF for dyno durability was greater than that for real road durability in CO, but contrary in NOx.
(16)For the in-use motorcycle emission-control components audit, most of them comply with regulation, some of them didn’t have identify numbers in secondary air system and catalysts, some of them had blurred identify numbers in canisters.
(17)The CO and HC emissions would be improved by way of maintenance; the CO deterioration factor value may increase rapidly for the high-mileage and over emission-warrant motorcycle research.
(18)For emission research in different speed, the CO and HC had greater emission in speed smaller than 20 km/h or greater than 50 km/h. The NOx had greater emission in speed greater than 40 km/h.
