This project was executed from April 1st, 2008, all related statistics are till February 28th, 2009. The motorbikes in controlling are 88.3%, those amounts returned without regular inspection are 77,748. There are 10 times in recognition of the license plates, the inspected amounts without regular inspection in shopping mall on holiday are 50,224, and the percentage of returning to inspect is 59 %. For special zones (including around industrial zones, sale markets and shopping malls) and the roads with more vehicles, the percentage of returned in noting and inspecting 6,007 motorbikes is 82%. Also we mail 36,003 overdue inform letters to low percentage of regular inspection countries, the returned percentage is 52.7%.
We inspected in 175 Regular Inspecting Stations of Taichung country for 881 times, 350 times for standard gas inspection, 175 times for whole-car inspection, 4 seminars for dealers, 2 assessments for inspecting staffs training, praise for excellent Regular Inspecting Stations and a business seminar.
For inspecting in Regular Inspecting Stations, there are 36 stations in “Without handing records to users” is the first one, and the second is “Non-shadow photo records aren’t clear” (22 times).According to 「Taichung district Inspection site for motorcycles causing air pollution performs inspection and records failed specifications」, in statistics, there are 91 stations in inspecting defects and 16 ones in recording wrong licenses of plate.6 of them have been closed due to their big mistakes, including LA2 for wrong labels; LA6 and L20 record wrong plate for 16 times and 2 times without plate photos; LD4、LA6 and L20 didn’t recall to Department of Environmental Protection, Taichung country and cause the populace were fined.L66 who inspect the motorbikes exhaustion in none-trained staff will halt it’s inspection for 3 months, others will halt for 1 month. In the management of Regular Inspecting Stations in Taichung country, the stations who inspect in none-trained staff will be fined to hale the inspection for 1 month, and they will be fined to be abolished in secondary times. Focus on the punishment is slack to central government, we suggest to modify the management to raise the inspecting quality.
Analyze to the motorbikes data in Taichung country, for 2 stroke motorbikes, Vespa is older and cause the inspections fault to 37.3%, it’s the worst one; for 4 stroke motorbikes, fault of Hartford inspection is 39.9%, because it’s made for oversea and follow their laws, the law in Taiwan is stricter than others, so it’s failure is higher in 4 stroke motorbikes and for all brands, 2 stroke motorbikes is higher than 4 stroke ones.
Research to the results, it due to the procedure of engine recycle in 2 stroke motorbikes is for two stroke. Though the engine’s combustion is incompletely, low efficiency, but for easy construction, cheap and bigger output power than 4 stroke motorbikes in same size. To avoid the power insufficient, the motorbikes in 50/90c.c. use 2 stroke engines most, and those 125/150c.c. use 4 stroke engines. But for 2 stroke engine, it burns in oil and gasoline mixture, it’s combustion incomplete produce white smoke and exhaust more pollutions than 4 strokes ones. And also, if 2 stroke motorbikes are inspected without warm-up it’s easier to make high percentage of failure in inspection. So, in the future we suggest to strengthen inspection in 2 stroke motorbikes if after warm-up or not. In the motorbike age, over 10 years 4 stroke motorbikes have higher average CO value and HC valve; the relation of motorbike age and CO and HC concentration is in direct ratio. The motorbikes over 10 years, their inspecting CO average valve is bigger than 2 %, and those over 9 years their inspecting HC average valve is bigger than 2,000 ppm. We suggest to continue the guidance for over 7 years motorbikes in interchanging to lower the pollution of 2 stroke motorbikes. The reduction of pollution exhausting for NMHC is 200.9 tons, and 1,219.3 tons for CO in 2008.
