Automakers call it by different names, but many have a system to deactivate some of an engine's cylinders and save you gas.

Gas cylinders store gases under high pressures. Gas cylinders can store both flammable gases, such as acetylene, and inert gases such as helium. Many countries have different color coding systems that ...

Bigger isn't always better: here's why engine designers obsess over bore, stroke, and cylinder size.

Air cylinders are pneumatic linear actuators driven by pressure differential in the cylinder chambers. Compressed gas (typically air) acts as the power to impart a force and cause actuation. The ...

Fluid power is routinely used in industrial applications, most often with cylinders providing linear motion. Among their advantages, hydraulic and pneumatic power-transmission systems offer: simple ...
