The mechanic uses an injector to add fuel to the engine.

Definition

Noun: 1. A device for forcing a fluid or other substance into something: An injector is a mechanical apparatus designed to introduce a liquid, gas, or fine particles into a chamber, system, or another substance under pressure. 2. (Engineering) A specific type of pump: In engineering, particularly in steam technology, an injector is a device that uses a jet of steam to draw in and force water into a boiler.

Usage

The word "injector" is a technical term. It is most commonly used in mechanical, automotive, and scientific contexts to describe a component responsible for the precise delivery of a substance. * It functions as a countable noun (e.g., an injector, two injectors, the injector). * It is often modified by the substance it injects (e.g., fuel injector, water injector) or its application (e.g., boiler injector).

Examples

• General/Mechanical Use:
  • The mechanic replaced a faulty fuel injector in the car's engine.
  • A steam injector is used to supply feedwater to the locomotive's boiler.
• Scientific Use:
  • The particle accelerator uses a specialized injector to introduce protons into the main ring.

Advanced Usage

• "Fuel injector": This is the most common modern usage, referring to the component in an internal combustion engine that atomizes and sprays fuel into the combustion chamber or intake manifold.
  • Modern direct-injection engines have very high-pressure fuel injectors.
• "Injector seat" / "Injector nozzle": These are specific parts of an injector assembly.
  • Carbon buildup can clog the injector nozzles, reducing engine performance.
