What is car tuning? What do you need to change in car modification?

Automobile modification refers to the modification of the external styling, internal styling and mechanical properties of the car produced by the automobile manufacturer according to the needs of the car owner, mainly including body modification and power modification.

According to the needs of the owner, the body is changed, the wheel hub is replaced, the chassis is lowered, the audio is modified, the interior and seats are replaced, the lights are replaced, the sound insulation is changed, and so on.

Modified cars, in fact, are upgraded according to the owner's preferences for the appearance, performance, and interior of the car!

Wantong Auto Repair is a very professional auto repair school, because it only offers auto repair majors, so it is very professional, offering engine construction and maintenance, chassis construction and maintenance, automotive electrical appliances, automotive electronic control, automotive sheet metal, automobile painting, automobile decoration and beauty, automobile modification, second-hand car evaluation and other majors, all of which are rational and practical integrated teaching.

See what you're going to change.

If it's just the appearance, I like to change it.

If you want to change the motivation.

That's quite a lot.

It also depends on what you change to.

Let's say you like to drift.

Or the push back feeling of acceleration.

Or is it high-speed exhilaration?

Each emphasis will produce different cars.

Generally speaking, the main purpose of most modified cars is to improve the surging power of the car, and power system modification is the top priority of car modification. To improve the power of the car, it is necessary to replace the nozzle, nozzle wire and sponge, fuel-efficient accelerator, water burner, horsepower booster, electronic rectifier and exhaust pipe. In addition, there are many people who want to improve the comfort and safety of the car, which requires the improvement of the chassis of the car, the main modification items include shock absorbers, brake steel throats, wheel rims, front top bar, rear top bar, front underframe, rear underframe, etc.

Audio modification should be the most common in car modification, audio modification is not the overall use function of the audio car, and it is also a good choice for **enthusiasts. Audio modifications are also permitted.

If you modify the car, you can modify the interior and exterior, including seats, electronics, and headliners! In terms of appearance, you can consider surrounding, body color modification, and wheel modification.

You can change the sound system to give you a different driving enjoyment.

You can change the color of the body to make your car shine more brightly on the road.

The car's driving computer, ECU power upgrade, can increase a lot of horsepower and torque, the program with hardware, air intake and outlet pipes, intercooler and so on to improve the effect is better, if you need ECU upgrades, you can look at the HDP special tuning program.

Car modification is not allowed in China, can only be registered as a repair shop, I only know that you need a business license, tax registration certificate, special industry certificate, automobile maintenance license, organization ** certificate, auto parts business license $$ modified car has certain restrictions, painting, the main color can not change, if it becomes to the vehicle bureau to re-register, the so-called main color specification is 90% of the body color.

In terms of suspension, the lower edge of the vehicle's large surround must not be lower than the tire axle by 5cm.

The engine is illegal to replace the engine without permission, and if you want to replace it, you need to re-register the engine number with the DMV, which is troublesome. There are not many restrictions on interior and exterior decoration. For power system modification, you need to go to a certified manufacturer for modification, such as ABT

The power system includes the engine, reinforced intake and exhaust system, transmission system, etc.

The problem of the domestic modification industry is not in the law, but in the technology, as well as the level of parts, an inferior part will kill the driver, and the tariff on imported parts is still 17%, and the Chinese automobile industry has not opened. At the same time, imported foreign components are expensive and often out of stock. Modified cars require the driver to have higher handling skills, especially in the performance modification part.

The domestic road conditions are not suitable for modified vehicles on the road, because the road potholes, lower suspension and replacement of large surrounds are likely to be scraped by speed bumps and other slopes. In some parts of the country, the wind and dust will make the car with enhanced air intake quickly replace the filter, which is really inexpensive over time. The level of mechanics in the domestic private car changing factories is limited, and the car modification is not car repair, and the car modification should be well known about the performance of high-performance components in each car and adjust the driving habits of the driver, and the tuning talent is in short supply.

Because China's auto industry is underdeveloped. There is no independent localized high-performance engine brand. 99% of the current modifications are focused on the appearance modification, and it is true that the technical strength does not dare to change the internal settings at will.

Modification depends on the development of this generation of mechanical engineering and automobile manufacturing college engineers, but it is more troublesome, do you want to drive a modification? It should be very marketable! You look at the introduction

1. Basic knowledge of natural gas vehicles.

First, the modified car refers to the modification of the external styling, internal styling and mechanical properties of the prototype car produced by the automobile manufacturer according to the needs of the car owner, mainly including body modification and power modification.

Second, legal knowledge.

Before decorating or modifying the car, it is necessary to understand the relevant laws and regulations to avoid falling into misunderstandings, otherwise not only will the car not pass the inspection, but it will even cause potential safety hazards and even be punished by law.

1 The new Road Traffic Safety Law clearly stipulates that no unit or individual may assemble a motor vehicle or change the structure, structure or characteristics of a motor vehicle without authorization. The structure of the vehicle includes four rigid standards of body color, length, width and height and the relevant technical parameters of the engine.

2. Before the licensed car is modified, it should be registered and declared to the vehicle management office, and the modification technical report can only be modified after the vehicle management office reviews and approves it. After the modification is completed, it is necessary to go to the vehicle management office to go through the modification and change procedures.

3. Whether the vehicle modification is legal, the key is to see whether the vehicle is consistent with the ** on the driving license, and whether the technical parameters of the vehicle are consistent.

The new regulations make it clear that changes to a car can involve changing the body color, changing the engine, or changing the body or frame. The owner can go directly to the DMV to change the registration within 10 days after the change. On the day of acceptance, the DMV will handle the relevant procedures for the vehicle owner, including endorsing changes on the motor vehicle registration certificate, taking back the driving license, and issuing a new driving license.

To put it simply, car owners do not need to seek the opinion of the DMV first.

Third, the decoration or protection measures of the appearance of the car can be selected according to the specific situation of the individual as follows:

1. Wax removal and light: When the new car leaves the factory, the shell has a protective film, so the new car should go to a professional car beauty center for wax removal and light, so that it can restore its beautiful and charming style.

2 Lacquered body: The appearance of the car is like the appearance of a person, and the appearance of a new car will be dark and darkened after a period of use. Therefore, when the new car is opened, the "glaze" is used to wrap the car paint to isolate it from the outside world, and there is no need to wax.

3. "Chassis sealing": It sprays a rubber resin with high adhesion and high elasticity on the chassis of the car in two times, which reduces the strength of sand and gravel impact, can play the role of anti-corrosion, anti-rust and sound insulation, and is also effective in resisting the strong corrosiveness of snow water and snow melting agent in winter.

4. Change of body color and body frame: You need to apply to the 6 branches of the DMV of the Traffic Management Bureau, and you can change it after the vehicle is confirmed and the DMV branch agrees. To change the engine and the usability of the vehicle, you can go to the vehicle management branch to register the change after the change is completed.

A modified car is to replace the original factory model, add or remove parts, or change the appearance. Reasonable and scientific modification of vehicles can make the original car safer and better performance. Modified cars are the performance of personal personality and the demand for improving driving performance and safety.

The car refers to the modification of some qualifications without following the regulations, and it is the car that changes its performance. This is against the law.

A modified car is a car that accomplishes a dedicated task. It is composed of equipping or attaching some special mechanism to the chassis of an ordinary car.

Such as fire trucks, liquid tankers, dump trucks, ambulances, engineering vehicles, garbage collection trucks, sprinkler trucks, propaganda vehicles, mobile stage trucks, concrete mixer trucks, etc.
