What is the difference between a carburetor and electronic fuel injection?

[KayleeMarie]

The differences between a carburetor and electronic fuel injection: 1. Different fuel supply methods: The carburetor mainly relies on the negative pressure (vacuum) in the intake tract to operate; electronic fuel injection relies on the ECU's internal program to control the injector's pulse width, thereby adjusting the fuel injection volume. 2. Different power outputs: Carburetors generally provide relatively lower power, while electronic fuel injection offers relatively higher power. A carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine. As a precise mechanical device, it uses the kinetic energy of the incoming airflow to atomize the gasoline. Electronic fuel injection is a type of engine that differs significantly from carbureted engines, including in operational methods. When starting an electronic fuel injection engine, there is usually no need to press the accelerator, as these engines feature cold-start enrichment and automatic fast idle functions, ensuring smooth starts whether the engine is cold or warm.
