Watch as we modify parts, experiment with crank radii, and bring high-tech Lego engines to life. This is the ultimate showcase of innovation, precision, and air-powered powerhouses! Make Toys ...

The engine is based around a single piston and runs on compressed air. The reduced parts count is a result of using the propeller axle as a key component in the engine itself.

The engine has no emissions, is very quiet, has constant high torque, a low parts count, no vibration and is very efficient - only 1 PSI of pressure is needed to overcome the friction to enable ...

A water-to-air intercooler has more parts but is ideal for tighter engine bays, while an air-to-air intercooler uses more piping. Both types of intercoolers perform the same task.

The Lego truck has a little engine running on compressed air, carrying around its fuel with it. The only batteries involved are powering the various servos to enable remote control.
