What is the principle of air cushion car?

The principle of the air cushion car is: air cushion module is the top of the carrier plate below is a ring-shaped airbag. When the air cushion module is inflated, the airbag expands to form a circle, air from the airbag through the air holes into the air chamber in the air chamber to build up the carrying pressure. The air is released in all directions to form a very thin air film with the ground. Because the air film frictional resistance is very small, so it can be pushed in any direction with a small thrust, rotation, positioning. Sedan can not hit the solution is as follows: 1, first of all should check the spark plug: because the spark plug is the key point of the ignition system of the car and the ignition system is the key point of the engine work, so the spark plug performance is good or bad relationship between the car's performance and efficiency. 2, battery power loss: its performance is characterized by the starter motor began to rotate, but the speed is not enough that is, powerless and then starter motor only clicking does not turn. Low winter temperatures and individual power equipment forget to close the vehicle will cause the vehicle can not start, especially in winter long-term short-distance low-speed use of battery voltage will be lower than the rated value of the start and can not run normally.
