This project implements motor vehicle noise and diesel vehicle emission inspection and management policy planning. The overall results include 1) Type approval of motor vehicle, 2) Conformity of production, and 3) Assistance in management planning and policy implementation; the description is as follows: 1.Type approval of motor vehicle: 1,703 cases of type approval of motor vehicles, including 285 cases of engine families (target 200) and 1,418 cases of noise vehicle types (target 800), were granted up to 30th November, 2020, and the number of differs by 23 cases compared with the average of 1,726 cases in the same period of the previous two years, same as the number of type approval in the same period of the previous two years. 2.Quality consistency management: A total of 326 noisy new car inspections were carried out. There were 1 train of large heavy locomotives with abnormal conditions, 1 train of large cargo chassis, and 1 train of bus test failure certificates. The improvement has been completed and passed Random retests, and the rest of the implementation results went smoothly. 1,422 times of statistical quality control tests 160 times of diesel vehicles and 1,262 times of noise), as required by the EPA. Those who fail to perform random inspections of new vehicles and independent quality control in accordance with regulations shall handle vehicle model approval and restriction operations, and continue to track which tests should be completed Models to ensure that the overall exhaust pollution and noise production quality are maintained. A total of 28 vehicle inspection cases were implemented for the actual noise vehicle inspection, one noise control information sticker was not paid, one ECU software version was inconsistent with the certified model, and the export model of a real vehicle muffler was inconsistent with the certified model. Please all 3 cases The manufacturer proposes an explanation of the reason and completes the correction and the modification of the certificate. 3.Assist management system planning and policy implementation: use diesel vehicles and noise phase six to promote the management system to synchronize with the international, streamline management practices, so that applicants can classify different types and specifications (such as silencers, sound insulation around the engine room) For the same model group, the quality control is maintained by strengthening the tracking of quality control statistics. Assist the Environmental Protection Agency to apply for noise certification for replacement silencers. The manufacturer or importer will select the model and silencer, prepare the qualification test report and related documents, and apply for accreditation, and complete the certification of the 31-combination number. 4.This plan shortens the technical judgment operation schedule from 3 days/item to 1 day/item through automated tool planning, which greatly improves administrative efficiency by 67%. In addition, the two-in-one verification administrative service reduces hardware maintenance and Operating system maintenance costs, improve operation and maintenance efficiency. In the process of promoting the sixth phase of the noise business, the average annual growth rate of the domestic quiet vehicle penetration rate in the past 4 years was as high as 3.6%; with the promotion of the replacement muffler certification system, in addition to indirectly improving the public noise status, it also completes and refines the noise control policies.
