Which automotive component replaced the carburetor in modern vehicles?

The fuel injection system represents a significant advancement in automotive technology, effectively replacing carburetors in modern vehicles. Carburetors mixed air and fuel in a specific ratio for combustion in the engine, but fuel injection systems optimize this process with greater precision.

Fuel injection systems utilize sensors and electronic control units to determine the exact amount of fuel needed for different engine conditions, enhancing efficiency, performance, and emissions control. This technology allows for more responsive acceleration and improved fuel economy, making vehicles both safer and more environmentally friendly.

In contrast, while components like the fuel gauge, air filter, and throttle body play essential roles in vehicle operation, they do not directly replace the function of carburetors. The fuel gauge monitors fuel levels, the air filter cleans the intake air before it enters the engine, and the throttle body controls airflow into the engine, but they do not mix fuel and air for combustion as the fuel injection system does.
