4 Barrel Carburetor

A 4 barrel carburetor is a device that mixes air with gasoline and delivers it to the intake manifold of an internal combustion engine. This carburetor has four distinct barrels. Each barrel has a throttle valve and venturi. The four-barrel model delivers fuel with greater precision and efficiency than the single or dual-barrel carburetors. Carburetors with four barrels are often found in high-performance gasoline engines. They provide greater power and torque output than two-barrel models. The sequential opening of the barrels at high engine speeds ensures quick and smooth acceleration. Browse and discover four-barrel carburetors for various automobile models on Alibaba.com.

A Comparison of a 2 Barrel vs 4 Barrel Carburetor

The two-barrel and four barrel carb perform the same function in an engine. They mix fuel and air and send the mixture to the combustion chamber. But they have obvious differences.

Concerning fuel delivery, the 4-barrel model provides more precise and efficient fuel delivery than the 2-barrel variant. Also, the carburetor with four chambers provides higher power and torque than the one with two chambers. The 2-barrel model is, however, simpler to maintain and more affordable than the 4-barrel model. The 2-barrel device is more suitable for smaller engines and older vehicles, while the 4-barrel carburetor suits high-performance vehicles.
