How to play a role with eobd2 the principle

Professional called, said the "tail" spoiler, more eobd2 common in the sport sedan and sport utility vehicles. Now there are also some ordinary vehicles to fit the "tail" spoiler. In fact, the role of spoiler order to reduce vehicle tail lift, rear lift than the front lift, it is easy to cause the vehicle to oversteer, the rear wheel to reduce the grip and high-speed stability deteriorates.
Walk through the city streets, you will find more and more sedans ass are mounted on the tail, cool shape so that it will always attract many eyeballs. Each vehicle are suitable for installation tail? The vehicle it will produce what kind of impact it? This period let us briefly look at the tail of knowledge.
Data analysis based on aerodynamic principles, we know that the car will be in the process of moving encounter air resistance, and this resistance can be divided into three aspects of the longitudinal, lateral and vertical rise force and air resistance and speed proportional to the square proportional, so the faster the speed, the air resistance is greater. In general, when the vehicle speed exceeds 60km / h, air drag on the car was very obvious. In order to effectively reduce and overcome the influence of air resistance in the high-speed running of the vehicle, it is designed to use car tail, and its role is to make the air to produce a fourth force on the car, i.e. adhesion on the ground, it can be offset part of the lift, the control floating car, reducing drag impact, the car can be close to the road, and thus improve driving stability. Note F1 race will find our concept before and after the F1 racing fixed wing, they are the bodywork provides nearly 60% under pressure, thus ensuring high-speed tires have enough grip to maintain stability of the body.
Addition to improve driving stability, the installation of the tail will also help save fuel. Traveling on roads, reduce fuel consumption perhaps obvious, if traveling the speed of more than 120km / h on the highway, automobile    obd2 scanner  tail is very obvious. Small displacement cars but in general does not recommend the installation of the tail, because the tail is used to increase the stability of the body, is very important for large displacement cars, small displacement of the car but will install exaggerated tail impact speed.
In addition to cars, the the roof rear of the wagon also installed a small tail, the tail on the roof part of the air flow is directed to the surface of the window after it passes, both to lift the rear of the vehicle to reduce, but also use of air to the surface of the rear window dust cleared, to avoid dust adhesion affect car rear vision.
Material currently on the tail of the market, there are three: First, in the original production of glass steel tail relatively paste together lines of the body. Aluminum alloy tail, people feel more exaggerated, but the diversion effect is good, and the price is moderate, but other material of tail slightly heavier weight than. Best tail material would also be regarded as a carbon fiber rear wing, high rigidity and high durability perfect combination, and is widely adopted by F1 racing, not only light weight but also the most beautiful tail.

 The spatial position   elm327  of the spoiler on the tail Some can adjust, adjust the way into both manual and automatic hydraulic column which automatically adjust the type, according to the vehicle speed to automatically adjust the angle of the spoiler. Generally recommend that consumers choose to manually adjust the type, hydraulic automatic tuning not only more expensive, but not as good as the manual operation convenience.
