The annual inspection of the car is something that every car owner has to go through, and the new car will be tested online after 6 years. If the annual inspection is not passed, the car will face scrapping. If the vehicle is released from trial, it will not be able to drive on the road. The annual inspection is to do a comprehensive physical examination of the car, which can kill some dangers in the cradle, but many car owners feel that the annual inspection of the car is "destroying the car".
The most feared thing for the owner of the annual inspection is the exhaust gas detection, exhaust gas detection is the analysis and determination of the components and concentration of the exhaust gas discharged by the motor vehicle in the idle speed or working condition, and the detection results of the automobile exhaust seriously affect the results of the annual inspection of the automobile. Every time at this link, the owner will be very nervous, one is worried about the exhaust gas detection, on the other hand, it is worried that the car is "stepped on and scrapped".
Because when the exhaust gas is tested, the staff will drive the car to the operation test bench, insert a large tube, and then start to slam on the throttle, and one foot of the throttle can soar to 5,000 rpm. Hearing the roar of the car, the owner felt heartbroken, he never stepped on 5000 rpm when he was driving, in order to detect the exhaust gas so vigorously stepped on the accelerator, how can the car not be damaged?
Many people think that one foot on the throttle 5000 rpm is a kind of harm to the car, is this true? Is the speed of 5000 rpm really an overloaded speed for a car? The results may not be as good as you think.
The staff of the testing station said that a foot on the throttle to 5000 rpm is in line with the testing standards, if the speed is not reached, the exhaust gas discharged by the car cannot meet the standard, which will affect the detection data. Vehicles that do not meet the annual inspection standards need to be re-rectified, participate in the test again, and the vehicles must be subjected to another operation of stepping on the accelerator. In order to be able to achieve the purpose of detection at one time, they press the throttle harder every time.
This detection method does not cause harm to the car, under normal circumstances, the speed of the vehicle will not reach 5000 rpm, the speed red line of many cars is 6000 ~ 7000 rpm, 5000 rpm is still within the red line, so the vehicle will not be harmed.
And now the automatic transmission car basically increases the speed protection, the daily driving process, the speed protection will limit the car. When the vehicle first starts, even if the throttle is pressed to the end, it will not exceed 2000 revolutions. When inspecting the car, because it is necessary to check whether the exhaust of the vehicle is qualified, it is necessary to let the vehicle reach a speed of 5000 rpm, and occasionally increase the speed once, which will not cause harm to the car, and the owner does not need to worry too much.
Many of the annual inspections of automobiles are routine items, which test whether the vehicle meets the standards for going on the road through the appearance of the vehicle. Exhaust gas detection is the test of engine performance, the engine not only affects the dynamic performance of the vehicle, the exhaust gas emitted by the engine will also affect the air quality. If the exhaust gas treatment is not up to standard, it will lead to air pollution and aggravate the greenhouse effect, so the transportation department is very strict about the detection of vehicle exhaust.
Some car owners do not want to participate in the exhaust gas test because they see black smoke coming out of the exhaust pipe, the engine makes a lot of noise, and they are worried that the car will have problems after the annual inspection. The car is a machine, it is affordable, there is no need to worry too much. If you want to make your car pass the annual inspection rate higher, you can check it yourself before the annual inspection to do maintenance for the car. If there is a modified part of the car, even if it is changed back.
