The Role of Carbon Fibre rear diffuser

Carbon Fibre rear diffuser

The automobile spoiler refers to the parts similar to the flip-flop tail wing mounted on the rear cover of the car. The rear diffuser plate refers to the additional plate mounted above the tail.

Some automobiles have spoilers at the tail, which make them look good, but that's not just for the sake of looking good.

When a car is running, air flows around the vehicle. When it flows through the roof, this part of the air begins to flow downward, and the velocity of the air flow here depends on the shape of the tail.

Many tails are designed more steeply in order to make the shape more beautiful, so the airflow speed will be faster, which will form the same effect as the wing to get upward lift. If the lift of the tail is greater than that of the head, it will easily lead to excessive steering, reduced rear wheel grip and poor high-speed stability.

Rear diffuser plate is also known as "automobile tail wing". It not only adds a sense of motion to the car's shape, but also reduces the lifting force of the vehicle while driving without increasing the vehicle's weight. By using the inclination of rear diffuser plate, the downward pressure of the wind is generated directly, thus effectively reducing the vehicle's driving at high speed. The air resistance generated during the operation not only saves fuel, but also improves the stability of the vehicle.

Take a car with 1.6L exhaust as an example. After installing the tail fin, the fuel consumption may not decrease obviously on the general road, but when driving on the highway, it can save about 10% of the fuel.

The rear spoiler of the F1 racing car is generally inclined by 15 degrees, and the pressure can reach more than 1000 kilograms at high speed.

However, rear diffuser plate also increases the wind resistance, such as the wind resistance coefficient of Fl is close to 1.0 (the average car is 0.3-0.5). So rear diffuser board must be "just right" in design, so that rear diffuser board can achieve the most reasonable degree between the increased wind resistance and the improved performance. So some rear diffuser boards are more obvious, while others are more "low-key", which is determined by the overall shape of the car!
