Gate

In transmission systems a device to guide a gear into any one position at any one time. In electronics a logic device for regulating electrical current flow according to input voltage levels.

GCM

Governor Control Module.

GDi

Gasoline direct injection. Petrol/Gasoline is injected directly into the combustion chamber under high pressure.

Gear

A method of providing leverage. Toothed wheel that meshes with another toothed wheel.

Gear Brake

Part of an automatic gearbox, the brake is often a band of friction material.
