Air

How It Works

An air car are powered by a compressed-air engine. The engine works like a steam engine except that high-pressure air instead of steam is used to push the

pistons. High-pressure compressed air is stored in carbon or glass fibre tank on the vehicle. This air is then fed through an air injector to the engine and flows into an expansion chamber, which expands the air rapidly by vapourizing it. The expansion of the air pushes down on the pistons, moves the crankshaft and powers the car. The compressed air tank usually weigh between 70 to 80 kg.

The following is a diagram of an air engine:
