1. Deflector
deflector (tail) Spoiler, automobile tail in addition to increase the aesthetic, it also has the function of increasing the stability of the cars, especially at high speeds, air flow through the tail It will produce a lower pressure, thereby reducing the lifting force of the air generated by the body, but the drag coefficient generally increases tail.
When the predetermined wind deflector scientific name is called tail, mounted on the rear of the car, corresponds to the reverse surface of the tail wing, which is above a plane, a curved surface below the vehicle at high speed, the lower tail air flow rate is greater than the above, the air pressure above the wing that is large, it will produce a downwardly pressing force, so that high speed stability of the vehicle can be enhanced.
Also during running tail spoiler may guide air scour vehicle, so that after a rainy day, after flushing stream will plate position, there will be no deposition of sludge, some hatchback tail mounted on the rear windscreen the above is a principle that can guide the air scour windshield.
