ELI5: Explain Like I'm 5

Injector

An injector is like a straw that helps cars and other machines suck gas or fuel into their engines. Inside the injector, there are tiny holes that let the fuel in, and then it gets sprayed into the engine, kind of like how you might spray water from a spray bottle. This fuel helps the engine to run and move the car or machine. Injectors are really important because they help control how much fuel goes into the engine at one time, which helps the engine run smoothly and efficiently. Without injectors, the machine would not be able to work properly and might stop running altogether.
