If you want to turn the yellow flag into a green one, you have to meet the condition of the vehicle, complete the emission retrofit, pass the field inspection and prepare the relevant materials. The yellow-marked vehicle shall be under 19 petrol trucks or petrol buses certified by the vehicle factory special service station technology and free of major accidents. Locally adapted emission routes, such as the upgrade of closed cycling sprays and the installation of three-dollar cleaners. After field tests of appearance and emissions have been completed, applications for replacement of motor vehicle registration certificates, driving permits, owner identification cards, etc. Are prepared. Policies vary from region to region, and their operation is regulated locally。
The retrofitting of emission technologies is a key element in the greening of yellow-marked vehicles. Careful adaptation of emission routes in strict accordance with local technology requirements may involve a variety of technical means. For example, the upgrading to a closed cycle jet system reduces the generation of contaminants by making the fuel jets of vehicles more accurate and fully burned. Or the installation of environmental equipment, such as a tri-channel catalyst, capable of effective catalytic transformation of carbon monoxide, hydrocarbons and nitrogen oxides in the tail gas into harmless carbon dioxide, water and nitrogen gas, which significantly reduces the pollution of tail gas emissions。
Field testing is an important level. Professionals conduct strict physical inspections of vehicles to ensure that the overall condition of the vehicles is satisfactory and that there is no apparent damage or inappropriate modifications. At the same time, it is even more critical that emission standards for vehicles be validated. Only those vehicles whose exhaust emissions fully meet the required environmental standards are eligible for the switch, while those that do not meet the standards continue to use the yellow standard。
In terms of material preparation, the owner must be careful and thorough. Motor vehicle registration certificates, original driving permits and copies thereof are essential to enable them to identify and identify the vehicles. Valid documentation of the owner of the car proves the legitimacy of the subject of the operation. The tail gas emission test report is a direct evidence of whether the vehicle has met the standard and only the conformity report can prove that the vehicle has the condition to change the standard。
In any event, the greening of yellow-marked vehicles requires that the owner be fully prepared, in strict compliance with the requirements, from various aspects, such as the condition of the vehicle itself, the retrofitting of emissions, the inspection chain and the preparation of materials, in order to successfully complete the switch and bring the vehicle into compliance with more environmentally friendly standards of travel。
