What's the plastic shell at the front of the car?
The plastic casing at the front of the car is called the front spoiler.
Generally, when the speed is more than 60km/h, the influence of air resistance on the car is very obvious. In order to effectively reduce and overcome the influence of the air resistance when the car at high speed, we designed a spoiler in the rear of the car, its role is to enable the air force to produce fourth cars, namely the ground adhesion, it can offset part of the aerodynamic lift, control the car go up, make the car close to the road. In order to improve vehicle stability effect. In addition to improving the running stability, the tail of the car will also help to save fuel. For example, the car with an exhaust capacity of 1.6L, after the installation of the rear wing of the car, on the general road, fuel consumption may not be obvious, but on the high speed road, it can save about 10% of the oil.
According to the analysis of the principle of aerodynamics, we know that the car will meet the air resistance in the process of running, this resistance can be divided into vertical, lateral and vertical forces in 3 aspects, and the air resistance and speed is proportional to the square, that is to say, at the speed of l20km lift, is 4 times the speed of 60km is 9 times. At 40 km, the faster the speed, the greater the air resistance.
