What is the purpose of fuel injectors?

The purpose of fuel injectors is to precisely meter and deliver fuel into the combustion chamber of an internal combustion engine. Unlike carburetors, which use air pressure to atomize fuel, fuel injectors use electronically controlled valves to spray a highly atomized mist of fuel directly into the intake manifold (port injection) or directly into the combustion chamber (direct injection). This precise control allows for:

* Improved fuel efficiency: By delivering only the necessary amount of fuel at the precise time, fuel injectors reduce fuel waste compared to carburetors.

* Reduced emissions: Precise fuel metering leads to more complete combustion, resulting in lower emissions of pollutants.

* Better engine performance: Precise fuel delivery enables better engine response and power output, especially at higher RPMs.

* Easier cold starting: Fuel injectors can deliver a richer fuel mixture to aid in cold starts.

In short, fuel injectors optimize fuel delivery for better efficiency, performance, and reduced environmental impact.
