National 6 emission norms have been implemented so far, many drivers want to buy national 6 models, and ultimately buy national 5 or the following models have long been inconsistent with the future direction of development, and even encountered the hazards of the current policy. Beijing Changan as a domestic car leading talent company, in recent years by the Chinese customers, that _ Beijing Changan national 6 what models it.
Beijing Changan National 6 models
Beijing Changan has National 6 emission specifications of the models are CS55, CS35plus, CS75, Yidong, CS85COUPE, Ruizhi CC, CS15, Yidong XT and other models. The vast majority of these models and at the same time equipped with national 5 emission standards, due to the full implementation of the national 6 must also be a long period of time, after all, the highest ownership of vehicles is the national 4 and 5, it is unlikely that a mandatory scrapping of the car, must be a certain buffer period. Here also advised to buy a car in accordance with their own economic development also have the location of the must to buy a car, like three or four cities to buy the National 5, but also enjoy preferential promotions, temporary and do not have to worry about the spread of the current policy to.
The difference between National 6 and National 5:
1, PEMS specific road emission testing is not only used in type inspection, but also used in the supervision and management of new production and manufacturing vehicles and in-use vehicle compliance.
2, clearly put forward a more rigorous compliance management control provisions, including type inspection and information disclosure, manufacturing consistency inspection, new manufacturing vehicle inspection, in-use vehicles in compliance with the physical inspection, and simplify the way to pass the judgment.
3, in the type inspection to improve the provisions of the circulatory system outside the emissions test, including automobile engine assembly platform non-standard circulatory system (WNTE) and the use of vehicle emissions detection system software (PEMS) to carry out the specific road emissions test, and improve the NOx emissions concentration value of the specific driving conditions of reasonable data information points.
4, nitrogen oxides (NOx) and fine particulate matter (PM) emission limit values and state five comparison of 77% and 67% stricter, and increased the total number of particles (PN) standard value provisions.
5, tightened the emissions manipulation equipment durability mileage regulations, and emissions related parts and components clearly put forward the requirements of the emissions shelf life.
6, automobile engine test working condition from the European region stability cycle system (ESC) and the European region transient cycle system (ETC) to a more symbolic global unified stability cycle system (WHSC) and global unified transient cycle system (WHTC).
7, PEMS specific on-road emissions testing is not only used in the type inspection, but also used in the new production of vehicles and in-use vehicle compliance supervision and management.
8, in the euro 6 car cut off detection system (OBD) based on the above, with reference to the British OBD policy and regulations clearly put forward the permanent fault code and other anti-hanging provisions; and for the first time in the remote control of the release of management method of the car cut off terminal equipment (remote control of the OBD) standards to the national industry standards.
9, the national six of the car compared to the national five of the car comparison, strengthen the injection pump and oil pump system software, this set of system software can improve the gasoline and diesel to do atomization, to reduce the emission of hazardous fine particles, this foreign six of the car is also the EGR waste recirculation system, GPF particulate matter catcher, this kind of is also all to reduce the emission of the system software.
