Most fuel injectors consist of a body that houses an electromagnetic coil and a sealing mechanism such as a pintle, ball or disc. These sealing mechanisms are usually kept close by means of a spring. Injectors are fully open or fully closed. The amount of fuel injected is determined by how long the injector is open or by how long the pintle, disc or ball is removed from its seat.
