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

[LaValerie]

The differences between a carburetor and electronic fuel injection are: 1. Different fuel supply methods: The carburetor mainly relies on the negative pressure in the intake tract to operate; Electronic fuel injection relies on the ECU's internal program to control the injector's pulse width, thereby altering the amount of fuel injected. 2. Different power outputs: The carburetor provides relatively less power; Electronic fuel injection provides relatively more power. A carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum created by the engine's operation. As a precise mechanical device, the carburetor uses the kinetic energy of the incoming air stream to atomize the gasoline. Electronic fuel injection is a type of engine. When starting an electronic fuel injection engine, there is no need to press the accelerator. The electronic fuel injection engine features cold start enrichment and automatic fast idle for cold starts, ensuring smooth engine starts whether the engine is cold or warm.
