| 英文摘要 |
This project contract ran from April 10, 2020 to December 15, 2020. During the period, a total of 19 noise testing operations for the replacement exhaust pipes of the Ministry of Environment were completed. At least 50 vehicles were notified in each operation, and a total of 960 vehicle times were notified. At least 30 vehicles were inspected at each site, and a total of 686 vehicles were inspected, of which 46 were unqualified.
Due to the operating standards for noise testing of replacement exhaust pipes, car owners who fail the current test will have two opportunities to retest. Therefore, although the total number of reserved vehicles is only 956, 182 vehicles have been scheduled for inspection more than once because they failed to pass the test, did not arrive for inspection, the exhaust pipe silencer plug was not welded, or other factors.
