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.

We stabilized the engine at peak horsepower at 6,100 rpm and then hit the button on the compressed-air supercharger and allowed the dyno to stabilize while we captured the numbers.

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.

We touched on a variety of onboard air systems last month (“Haul-Along Huffers,” Mar. ’14), and this month we show you a new version of an old reliable system, the engine-driven compressor ...

Whether you're driving a brand-new car or something that's seen better days, there is always the chance that you'll get a ...

A fully functioning compressor is necessary for the air-conditioning system to provide peak performance. On most cars, A/C compressors are driven by an engine-accessory belt.

A ­former engine developer for Formula 1, Negre began work on his air engine in 1997. By 2004, with a raft of patents under its belt, the MDI team was showing off working compressed-air car (CAC ...

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.
