Installation of large envelope: the so-called large envelope is actually the turbulent component of air. It originated from motor racing, because high-speed vehicles will encounter higher air resistance. Large-size coaming can improve the airflow around the car body and improve the stability of the car body. Automobile shell is a kind of glass fiber reinforced plastic product, painted with the same color as the car body, and integrated with the car body. Compared with the original bumper on the car, the grade is much higher. When installing a large enclosure, the owner shall first determine the transformation scheme according to his own preferences, and then the professional transformation company shall carry out the construction. Generally, it is necessary to go through the technological processes of mold making, steel brushing, mold repairing, putty scraping and painting. When installing a large chassis, we should consider the smoothness and firmness of the surface to choose a large chassis product. Another thing to note is that the impact resistance of FRP is poor, so it is generally not necessary to dismantle the original bumper product when choosing to surround it. Therefore, the safety of the vehicle will not be reduced because of the large shell.
Sound insulation project: completed in three steps: vibration reduction, noise reduction and sealing. Doors, trunk, chassis, hood and roof are all places that are prone to air friction noise. Most of the noise is introduced into the car through the suspension system, chassis, trunk and door of the car. Therefore, the door and trunk can not be ignored in the basic sound insulation project. For engine noise, a film can be pasted under the hood-an advanced sound-absorbing foam acoustic material, which can absorb and consume a lot of engine noise, suppress the vibration of the hood, block the heat emitted by the engine, and the effective rate reaches 97%, protecting the paint surface from long-term high temperature damage. In winter or cold areas, this film can also play a role in heat preservation and protect engine compartment parts from frost cracking. Owners should pay attention to the fact that all sound insulation materials must meet the requirements of relevant fire protection grades, so as to ensure vehicle safety and reduce vehicle weight.
Tail installation: many vehicles have something as prominent as a bird's tail, that is, the rear, which is scientifically called a spoiler. Don't think the tail is an ornament. Through the downward pressure generated by air acting on the tail wing, the car can be controlled to float upwards, so that the car can drive close to the ground, improve driving safety and save fuel. At present, the tail of most cars is made of glass fiber or carbon fiber, which is light and tough, and the shape and size are determined by the designer's precise calculation. Tail wings that are too big or too small can't play their due role, and even increase the driving resistance of the vehicle. There are all kinds of tail fins in cars, and the tail fins of racing cars are usually installed relatively high. This is to prevent the downward pressure acting on the tail from acting on the car body again, thus offsetting the effect of the tail. For low-speed vehicles, the tail plays a more beautiful role.
System transformation: There are many methods, except replacing high-performance brake discs with higher-grade brake oil or replacing high-pressure brake oil pipes with metal materials. Another method is to replace it with a larger brake multiplier to increase the auxiliary thrust of the brake pedal. Brake pads can be basically divided into two categories, one is for ordinary driving, and the working temperature is between 50 and 450 degrees; The other is racing. The operating temperature range is 250 to 850 degrees. High-temperature brake pads are not suitable for ordinary pavement, because they can't play an ideal braking effect before reaching the working temperature, which is easy to cause danger.
Shock absorber and suspension system: the modification of suspension system can be roughly divided into replacing shock absorber, strengthening suspension structural rod and installing balance rod. One of the most influential and modified projects is the shock absorber. The modification of the shock absorber is actually to change a shock absorber with hard damping, good quality and full cooperation with the spring. Choosing the right shock absorber is very important, and it is especially difficult to reach a compromise between comfort and handling. But in pure competitive racing, everything is centered on manipulation, so a set of rigid shock absorbers will undoubtedly be more practical for modified cars.
Exhaust pipe: the engine will exhaust exhaust gas after doing work, and the exhaust efficiency is directly related to the engine efficiency. At the same time, the exhaust efficiency needs to be strengthened while the intake air increases and the combustion state is good. Now it is mostly changed to direct exhaust, that is, the middle and front sections of the exhaust system are changed, and the muffler and other purification devices are removed to shorten the whole exhaust process and discharge the exhaust gas after simple treatment. The vehicle will accelerate faster after improvement. The modified straight bucket will make a deafening sound when accelerating, but the vibration should not be too big, otherwise it will aggravate the driver's fatigue and irritability when driving the vehicle for a long time.
