For regular inspection of cars, I think everyone is not very clear, especially for vehicles with an age of more than 10 years, a regular inspection is equivalent to an overhaul. The first impression of car owners on the annual inspection is mostly "scratching the car". Mainly because of the exhaust gas inspection items of the annual inspection. In this project, the engine of the car is operating at a high load. You know, although the design of the car itself can maintain a high speed state, the vehicle is often in a cold car state during the annual inspection, and there is no hot car in the early stage, and suddenly entering this state in a short period of time will naturally affect the life of the engine. In normal operation, the engine speed will not exceed 4,000 revolutions.
Even vehicles that have been on the road for more than 10 years will maintain a speed of about 3500 when the speed reaches 120km/H, but in cars, the engine speed will often reach more than 5000 rpm when the exhaust gas is detected, and sometimes exceed 6000 rpm. The car itself is the owner's personal belongings, and some car lovers will not drive violently like pressing on the accelerator and braking hard. In the face of the employee's unfriendly and violent annual inspection, it is naturally unacceptable. At the same time, not all vehicles can pass the annual inspection. Especially after the upgrade of emission standards, vehicles below The fourth country are becoming more and more difficult, and a failed inspection requires repair, and often unqualified inspections can only be scrapped. The annual inspection of the car can make the old car feel very stressful. In the automotive industry, many car owners have called for the cancellation of regular car inspections. From the current situation, it is obviously unrealistic to cancel the regular inspection of motor vehicles, but it is possible to optimize the regular inspection program, further avoid the impact of violent periodic inspections, and give the best treatment to all motor vehicles.
Private car annual inspection cycle, for cars generally driving on the road, it is not necessary to participate in the regular inspection of the car every year, and the regular inspection of private cars has periodic regulations. New cars do not need to undergo annual inspections within 6 years, just receive environmental protection labels. With the rapid development of the Internet, car owners can directly get the electronic version of the logo online, without going to the vehicle management office. Between 6 and 10 years, check-in every two years. That is, online checks are required in the sixth and eighth years. In the tenth year, it needs to be checked every year. After the vehicle reaches 15 years of age, it needs to be checked online every six months. Whether a private car passes the annual inspection will determine whether it is eligible to continue driving on the road. If it cannot pass the annual inspection, the vehicle can only be scrapped. The scope of exemption from inspection for private cars has been expanded
According to the above, private cars will be exempt from inspection for 6 years after purchase. The range of such vehicles is not small, but does not include vans. With the increase in the number of cars, the annual inspection rules are also constantly adjusted and updated. So far, the exemption range includes small cars with less than 6 cars, but more than 6 vehicles are no longer within the scope of exemption, which is pressured on many MPV and SUV owners. With the opening of the fertility policy, more and more families need to buy 7 vehicles, and the scope of exemption from inspection is expanded. Therefore, only by expanding the scope of exemption from inspection of private cars to less than 9 vehicles can it meet the current needs. However, models placed in engines like vans are not included. With the continuous development of science and technology, the annual inspection of automobiles has also kept pace with the times, and some testing items have been cancelled, integrated and cancelled: electronic handbrakes, lamp deviations, in-car noise, speed errors, and automobile suspension testing projects.
At the same time, some inspection items have also been added to the annual inspection, including OBD inspection and tire inspection. OBD inspection is mainly to check the failure of the car, connect the car transmission computer, and judge the internal fault of the vehicle. This is the same as the new threshold for older models. In particular, if you add that many old cars have OBDs, many false alarms, and insufficient parts that cannot be replaced, the pass rate at the time of annual inspection will be greatly reduced.
