The difference between carburetor and throttle

These are two things: the throttle is only a matter of controlling the air volume, that is, a steel wire rope is used to guide the throttle from the throttle to the carburetor, which was used in previous cars, but it has been basically eliminated now. Some big cars may still be used, but small cars are basically controlled by EFI. Carburetors mix oil and clean air outside the cylinder and transport them to the cylinder for combustion. EFI is to inject oil into the cylinder regularly and quantitatively. The intake manifold of the throttle valve is straight. Inhale clean air and send it into the cylinder, and then ignite 1. One is mixed outside and sent to the inside for ignition, and the other is sent to the inside for ignition respectively.
