Abstract
This project was implemented on December 21, 2017. The content of this project includes leasing and maintaining 30 sets of smoke filter, regularly conducting complete smoke filter function tests based on diesel car inspection methods, and holding four training advocacy seminars each year. At the time this report was issued, all the work items had already been completed. The implementation results are as follows:
1. Follow-up smoke filter installation work
The original Jiadong Township vehicle (license 005-SJ) was scrapped on April 3, 2018, so the smoke filter was reinstalled on another Jiadong Township vehicle on April 11, 2018 (license 4002-MH).
The original Wanluan Township vehicle (license 486-TG) was removed from operation on July 31, 2018, so the smoke filter was reinstalled on a Chaozhou Township vehicle on July 31, 2018 (license 033-SJ).
2. Smoke filter maintenance work
Between January and December 2018, maintenance of the regeneration combustion system was conducted 12 times (monthly maintenance). During the monthly vehicle regeneration combustion system repair/maintenance process, a total of 30 vehicles underwent voluntary parts maintenance/replacement (including those malfunctioning ones reported by cleaning teams). In total, 133 repairs were conducted.
3. Vehicle regular inspection
When a vehicle with a smoke filter installed has been driven 3,500 km or for four months (whichever comes first), it must undergo at least one complete smoke filter function test. To understand the operating efficiency of the regenerative combustion system, the horsepower difference shall not be higher than 10%, the opacity shall not be higher than 0.6m-1, or the black smoke reduction rate should be higher than 80% or more. As of the issuing of the final report on December 20, 2018, the first, second and third re-tests were conducted on April 11th, August 14th, and November 28, 2018, respectively.
4. Vehicle self-inspection and maintenance
The first self-testing and repair was conducted from January 11th to January 17, 2018.
The second self-testing and repair was conducted from April 13th to April 30, 2018.
The third self-testing and repair was conducted from June 21st to June 29, 2018.
The fourth self-testing and repair was conducted from October 3rd to October 23, 2018.
5. Training
The four training advocacy seminars were held on March 21st, May 23rd, October 17th, and December 3, 2018.
6. Benefit evaluation
The black smoke test results showed that the current overall average black smoke opacity removal rate reached 94% and that the opacity values are all under 0.4m-1(including). We estimate that the annual PM2.5 reduction quantity is 0.152 tons and posit that there are positive benefits to black smoke reduction.
