Huang Biao limit range extended to Xiamen Island

Huang Biao limit range extended to Xiamen Island
Glossary: ​​Huang Biao car
The name of the highly polluting vehicle is a petrol vehicle that does not meet the national I emission standard, or a diesel vehicle that does not meet the national III emission standard. Because it is affixed with a yellow environmental protection mark, it is called a yellow mark vehicle.
Although the yellow mark car is less than 10% of the number of motor vehicles in Xiamen, its exhaust pollution exceeds half of the total vehicle emissions! The “Regulations on Prevention and Control of Motor Vehicle Exhaust Pollution in the Xiamen Special Economic Zone” has been in force for the past two years.
Stage-by-stage bank + subsidy "two-pronged approach" to eliminate yellow-label vehicles
According to the statistical data of the functional departments, about 62,000 vehicles have been tagged in Xiamen City. Since April 1, 2012, peak-term measures have been implemented for Huangbiao Vehicles at Chenggong Avenue and Xianyue Road. By the end of September 2013, a total of punishments have been imposed. The environmental protection mark limits the number of illegal vehicles to nearly 22,000 vehicles, and the total fine is 4.826 million yuan.
Starting from June 1 this year, the scope of Huang Biao’s restricted trip will be expanded to Xiamen’s main island and will be promoted in three phases: first at the peak period and then at the main time limit, with a plan to achieve a full-time limit in 2016. In addition, the "Xiamen City Yellow Label Vehicles to encourage early retirement subsidies program" is expected to be introduced before June this year.
Huang Shifu, deputy director of the Standing Committee of the Municipal People’s Congress and head of the law enforcement inspection team, said that the exhaust pollution of motor vehicles has become one of the important factors affecting Xiamen’s air quality. For this reason, the law enforcement inspection team recommended that the inspection of motor vehicles should be strictly prohibited. , The exhaust emissions compliance as pre-conditions for industry access, will not be issued on the yellow label car operating license, speed up the pace of the yellow mark car out of renew.
The Municipal Environmental Protection Bureau said that before 2015, about 29,000 vehicles will be phased out before 2005, and they will be phased out by 2017. In addition, a black smoke detection device will be installed on the five island passages to prevent foreign yellow marking vehicles from entering the island.
Fuel regulation is not in place
The quality of vehicle fuels has a great influence on the exhaust conditions of motor vehicles. The Regulations stipulates that “the municipal government shall take measures to strengthen the supervision and inspection of the fuel quality of vehicles and regularly announce the results of supervision and inspection.” The terms have not been implemented and the fuel quality of vehicles is still a vacuum for supervision. Last year, the city's industrial and commercial bureau accepted a total of five complaints concerning vehicle fuel, and consumers focused on the problems of flameout, problems with exhaust pipes, and the inability of vehicles to start after refueling.
The Law Enforcement Inspection Group recommends that the results of the supervision and inspection be regularly announced in accordance with the requirements of the Regulations to ensure the quality of vehicle fuel supply in Xiamen City and reduce the total emissions of motor vehicles. At the same time, the promotion of low-energy, low-pollution new energy vehicles.
In order to improve the vehicle pollution supervision measures, the preliminary work of several projects will be launched one after another this year, such as exhaust pollution monitoring platform, motor vehicle exhaust testing center of Xiamen North Railway Station, motor vehicle exhaust pollution prevention and control system, and motor vehicle information electronic archives. Systems, etc. These projects were also included in the Xiamen City Clean Air Plan (2014-2017). Among them, the vehicle exhaust pollution prevention and control system is expected to be put into trial operation before September this year.

High Precision Machining

High Precision Machining is defined as a process of changing the dimensions or the performance of workpiece with machining facilities.

According to the temperature of the workpiece while in machining, high precision machining can be divided into cold working and hot working. Usually, machining under indoor temperature, and won't change cause chemical change or phisical phase change is named cold working. On the other hand, if under temperature, higher or lower than room temperature, which will lead to chemical changes or phase changes, it will be called as hot working.

For high precision machining, the machining tolerance can be up to 0.0001-0.001mm, the surface finish Ra can be 0.02-0.1um.

Machining precision is to describe the actual geometrical parameter of the part after machining, such as the size, the form, the position, comparing with the theoretical geometry parameter. The difference from these two parameters is the machining tolerance. The number of the difference show the machining accuracy, the bigger, the lower of the machining precision, the smaller, the higher machining precision.
