Compressed air car principle
The principle of compressed air vehicles is very simple. Now the principle of generating power in the car engine is to push the piston by the compression of the air and the expansion of the combustion. The air engine car is to compress the air outside the car and put it in the car. Because when the air is released, it expands to generate pressure. Using pressure to push the piston in the cylinder does not need to burn, it will not emit harmful gases and will not cause pollution.
The true engine principle builds, the security structure design!
The assembly is simple, the operation is easy, and the built-in pump rod is built. As long as the air bottle is filled with air, the car can be pushed to 50 meters in 35 seconds through air pressure.
Compressed air vehicles are science and toys, manual training, image thinking, colleagues with science, mathematics, no blood cross-domain knowledge, in the assembly process to cultivate the ability to solve problems, early development of children naked thinking and creative inspiration.
