Safety first, which car parts can not be modified at will

"Team Work" refers to a team of multiple people working together to accomplish a task, and each part of the car is completing "Team Work" while we drive. But in teamwork, because each person's ability and characteristics are different, so highly efficient team members must be after some time, and each person has a specific standard of work. In the car "team" is the same because each component can not be independent of the friction coordination, so the standard of parts in the car will be much higher than the human standard, this standard is also the subject of our words today.

In addition to the mechanical design of automotive parts standards, there is an aging rate, sealing degree, EMC interference, exposure testing, lighting standards, reliability, and other complex projects, each project is for different parts that need to meet the conditions. Of course, each car manufacturer because of the concept of car manufacturing and production process differences, their standards have major differences.

Whether the luxury version or beggar version, each part in the car factory configuration of accessories has its standards. In addition to the design specifications, each part has its working environment and work functions, which means that each part needs different materials, workmanship environment, corrosion resistance, dust, and water resistance. To ensure that each part can work steadily in a team, these standards have also become a necessity.

Materials in addition to the characteristics of heat and cold shrinkage lie in different temperature conditions mechanical properties will also be an important impact. As a means of transportation may face the summer nearly 80 degrees in the sun, but also may face -20 degrees in the snow and ice. So the car in the assembly of each component before the material characteristics of the various extreme test is a must to complete the project.

Perhaps many car owners in the repair of cars or replacement of certain parts cheap and did not choose the original parts, since then the vehicle will continue to occur some minor problems. These minor problems and your choice of accessories have a great relationship, do not meet the original standard accessories can not meet the requirements of users are not counted, and even affect the normal work of other accessories, causing failure.

The natural environment of acid rain, dust, ozone, and other substances will cause a certain degree of corrosion of metal, and plastic material components, coupled with the wind and sun, and the aging of auto parts is inevitable. After the aging mechanical performance certainly decline, to ensure the normal work of the entire "team", manufacturers will require each component by their standards for testing.

For those who like to modify friends to pay special attention, you improve the performance of a certain part of the mechanical parts, which also means that the workload of other mechanical parts related to it will also increase. So you should choose something that meets the original standards or consider strengthening the performance of other related parts as much as possible when modifying.

Changing the wheels in a low-profile vehicle to high-profile wheels is something that many owners do, and some of them feel that since they have been changed, they should simply change to a larger one, which strengthens the performance of the tires but increases the wear rate of the rubber on the suspension. This is just one of the cases, for each part of the car is closely related to the modification of the time to act according to the strength.

EMC (Electro Magnetic Compatibility) electromagnetic compatibility, is the ability of a device or system to operate in its electromagnetic environment in compliance with the requirements and without producing intolerable electromagnetic interference to any equipment in its environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment to its environment during normal operation cannot exceed a certain limit; on the other hand, it means that the apparatus has a certain degree of immunity to the electromagnetic interference existing in its environment, i.e. electromagnetic sensitivity.

Electronic equipment in the signal transmission and level changes will produce certain electromagnetic waves, the number of electronic equipment inside the car today is huge, so electromagnetic compatibility testing is very necessary. Each manufacturer has developed different markings for their cars to ensure that individual electronic devices do not affect each other when they work.

EMC is a very critical indicator in cars with multiple electronic systems, and failure to meet the requirements can affect the work of other electrical devices. When the car is moving at high speed, the consequences can be imagined if the brake signal is incorrectly passed once or if the brake signal is not sent to the ESP unit because of interference.

Since the introduction of xenon headlights, many car owners have also been poisoned by the lights and set off a craze to change the headlights. Perhaps you modify the light to be beautiful, light much brighter, but have you considered whether it will not give the car the impact of illumination, and will not cause visual errors to the opposite car drivers? On the narrow two-way road, out-of-specification headlights are harmful to people and themselves.

The dazzling lights can win you a lot of turnovers, but on the highway, your opposite car can't see anything else but your blinding lights. So you want to carry out the lights modification friends to act according to their ability, the first consideration is safety, followed by the lights.

The previous rumors of a model because of the installation of a certain rear-mounted xenon headlight assembly burned the car computer, so we should be very careful when choosing rear-mounted accessories. The original electrical equipment does not have the standard electrical equipment and is not only prone to problems but also causes other electrical equipment to short circuit, and burned.

We will DIY many things in life, such as furniture, computers, and other equipment, if there is a point where they go wrong I just need to restart a button or readjust. But if this happens in a high-speed car, it is not as simple as restarting, you may be paying a life. So we must first consider safety when choosing aftermarket accessories for modification, followed by the effect. At the same time, at present, according to my understanding, CVC Wei Kai Institute of Testing Technology is speeding up the conversion between international standards and national standards to speed up the standardization of various standards in the automotive market.
