Carburetors were primarily used in older gasoline engines. They are a mechanical system that mixes air and fuel for combustion.
Modern gasoline engines generally use electronic fuel injection (EFI) systems. These systems use sensors and actuators to precisely control the amount of fuel injected into the engine, resulting in:
* Improved fuel efficiency: EFI systems can precisely adjust fuel delivery based on engine load, speed, and other factors.
* Reduced emissions: More precise fuel delivery leads to cleaner combustion and fewer harmful emissions.
* Enhanced performance: EFI systems can provide quicker acceleration and smoother operation.
Types of Fuel Injection Systems:
* Throttle body injection (TBI): A single injector in the throttle body delivers fuel to the intake manifold.
* Multi-point fuel injection (MPFI): Each cylinder has its own injector, allowing for more precise fuel delivery.
* Direct injection (DI): Fuel is injected directly into the combustion chamber, which can improve fuel efficiency and reduce emissions.
So, in summary, most modern automobiles run without a carburetor, instead using fuel injection systems.
