When it comes to the interior modification of commercial vehicles, everyone will think of changes in the appearance or interior of the rear wing, wheel hub, and body pull flowers. There are a wide variety of car modification products that came into being. And most products have strong claims to improve the performance of so-and-so. Is it really what the dealer says? In fact, after you choose to be dizzy and dazzled, you will find that it is not known how many uses it will come in practical use.
Let's take a look at the misunderstandings of Guangzhou Lego Automotive Technology Co., Ltd.:
1. Blindly installing the rear wing and rear wing has become a fashion, but not all models are suitable for installing the rear wing, because the function of the rear wing is to increase the stability of the body, This is the key for large-displacement vehicles, but for small-displacement vehicles, the installation of the rear wing will have a certain impact on the speed of the vehicle. The rear wing is a spoiler part. If the rear wing is only installed to achieve an exaggerated or aesthetic effect, it will have some negative effects. Because the role of the rear wing is to improve the down pressure and body dynamic balance at high speed, but it needs to be carefully adjusted to achieve the desired effect. 
2. When turbocharging technology becomes a current trend, many people's hearts also begin to prepare to move and consider turbocharging their cars, but the expensive cost is an insurmountable gully. At this time, the electric turbocharger appeared in the artifact, which is low in price, easy to install, and has functions to increase power and reduce fuel consumption, allowing many people to take out their wallets. The motor is set behind the turbine blades, and the air is blown behind by the turbine blades and then flows to the throttle through the irregular motor and bracket. Its huge structure will cause a lot of intake resistance, but it will cause difficulty in intake at medium and high speed of the engine.
3. Through the internal research of the automotive electronic rectifiers displayed by the online merchants, it is found that most of the automotive electronic rectifiers are capacitor arrays composed of large capacitors in parallel, and some are also installed with several relays for shutdown and power-off protection. Its functions are claimed to be voltage regulation, rectification, and sound quality improvement, but I think it is actually using capacitor arrays to increase and stabilize voltage. According to the principle of capacitor wave peak, when the regulator is 13.8V at high speed, the voltage of the whole vehicle may be as high as 15V. Although the on-board trip computer, DVD host and other electronic devices also have voltage regulation, since the working V of the on-board electronic devices is within the DC range of 12 units, and the voltage regulation of the battery is added, the voltage adaptation range of the electrical equipment is not designed to be too large. Causes the threat of high voltage shock and accelerates the aging of electronic components. According to the service regulations of most automakers, the 4s will not be covered under warranty due to problems with the vehicle caused by the owner installing the equipment themselves.
