1. Execute motorcycle new model certification issuance and conduct new motorcycles selective tests;
2. Promote to establish system for the motorcycle production and sales by manufacturers and reported to EPA as reference file electronically;
3. Execute in-use motorcycles investigation tests;
4. Cooperate with EPA to implement relevant emissions control measures and researches. The description of detail achievements are as follows:
(1) To examine new motorcycle model certificate applications; verify on continue use, extension, and amendment of certificates; totally 175 certificates were being issued which include 425 motorcycle models. Some Stage 5 emissions standards compliant motorcycles, the CO and NOx pollutant certification test results are close to the regulatory limit values and need to be verified by the future new motorcycle selective tests and to enhance the in-use motorcycles managements.
(2) Conducted 134 new motorcycles random selective tests, the test results have shown that 4 engine families failed the preliminary tests but 2 engine families passed the confirmation tests, 1 engine family gave up the confirmation test, 1 engine familiy still had the chance for the confirmation test, that means the production quality control for these motorcycles should be enhanced.
(3) This year 64 motorcycle emission control devices were being inspected, 6 motorcycle engine families with emissions control device identity numbers are not consistent with reported numbers which are the faults are on manufacturers requested to be corrected.
(4) This year 22 motorcycle durability test plans were being examined and 6 applications were being canceled.
(5) As to the examination on manufacturers’ quality control, the defects of last year have been improved. Overview the quality control test results, CO and NOx emission values of some engine families were high or with large variant.
(6) The total emissions in 2011 are summarized as follows: CO 151,182 tons, THC 67,937 tons and NOx 9,077 tons. Compare to the 2010 emissions values, CO reduced about 2,104 tons(1.37%), THC and NOx were 1,242 and 134 tons (1.80% and 1.45%) respectively.
(7) As to the 2012 green motorcycle ranking, preliminary, 4 domestic manufacturers with 10 engine families were being selected as green motorcycles.
(8) As to the certification process electronically, besides performing the system function maintenance continuously, debugging, and keep the system function normally, this project also overviewed the execution and management functionality and finished some updates and amendments. This project also planned and established the connection interface for the certification test reports, the vehicle registration approval data, electronic payment operation for certification, and the pollution-noise two in one certificate operation.
(9) As to the in-use motorcycle recall investigation tests, 10 engine families were being tested and 45 motorcycles passed, 5 motorcycles, which had been tampered with emission control equipment, had high emissions.
(10) As to the test results analysis for the Stage 5 emissions standards compliance motorcycles, the HC emissions were within half of the regulatory limit values for motorcycles with engine displacement less than 150 cc, others were close to the limit values. About 40%~70% Stage 5 emissions standards compliance motorcycles could comply with the Stage 6 standards, but only 25% of the individual test motorcycles could comply with the Stage 6 standards.
(11) If the EU certified test results being converted to the regulatory conditions in Taiwan, near 60% motorcycle types would comply with our Stage 5 standards. If the Japan Stage 2 compliant motorcycle test results being converted to the regulatory conditions in Taiwan, none would be comply with our Stage 5 standards.
(12) The Stage 6 emission standards draft have been completed, and will start in 2015.
(13) The open device for exhaust emission measurement showed no difference compared to the closed device in test results.
(14) The in-used heavy motorcycles test results showed higher deterioration in CO emission.
(15) As to the idling stop analysis, the emissions with idling stop function on were higher than that with idling stop function off, the emission increment with idling stop function on had no relationship with the idling time percentage in driving pattern.
(16) As to the deterioration factors analysis, the values were in between 1 and 1.2 in Taiwan, but in the US, most of the deterioration factors were in DF equal to 1 or greater than 1.5. The 90 percentiles of deterioration factors for CO, HC, and NOx were 1.769, 1.81, and 1.762 for US data, and were 1.237, 1200, 1.242 for Taiwan data. The deterioration factor showed no difference in factors such as manufacturers, displacements, fuel supply manners, and durability manners.
(17) As to the checking on in-use motorcycle emission control devices, 10 engine families emission control devices were being checked and consistent with the certification information.
(18) The modified regulation drafts governing durability test procedure, tailpipe emission test procedure, evaporation test procedure, and issuance of motorcycle configuration emission certificate have been completed.
(19) As to the research on aged motorcycles, the CO and HC emissions will be improved if performed maintenance. Most of the motorcycles didn’t show obvious deterioration.
(20) As to the research on emissions in different constant speeds, the emission were lower in 30~40 km/hr compared to other speeds.
